DESCRIPTION
OPA343 series rail-to-rail CMOS operational amplifiers
are designed for low-cost, miniature applications. They
are optimized for low-voltage, single-supply operation.
Rail-to-rail input/output and high-speed operation make
them ideal for driving sampling Analog-to-Digital (A/D)
converters. They are also well suited for general-purpose
and audio applications as well as providing I/V conver-
sion at the output of Digital-to-Analog (D/A) converters.
Single, dual, and quad versions have identical specifica-
tions for design flexibility.
The OPA343 series operates on a single supply as low as
2.5V, and input common-mode voltage range extends
500mV beyond the supply rails. Output voltage swings to
within 1mV of the supply rails with a 100kΩ load. They
offer excellent dynamic response (BW = 5.5MHz,
SR = 6V/µs), yet quiescent current is only 850µA. Dual
and quad designs feature completely independent circuitry
for lowest crosstalk and freedom from interaction.
The single (OPA343) packages are the tiny SOT-23-5
surface mount and SO-8 surface mount. The dual
(OPA2343) comes in the miniature MSOP-8 surface
mount and SO-8 surface mount. The quad (OPA4343)
packages are the space-saving SSOP-16 surface mount,
SO-14 surface mount, and TSSOP-14 surface mount. All
are specified from –40°C to +85°C and operate from
–55°C to +125°C. A SPICE macromodel is available for
design analysis.

APPLICATIONS INFORMATION
OPA343 series op amps are fabricated on a state-of-the-art
0.6 micron CMOS process. They are unity-gain stable and
suitable for a wide range of general-purpose applications.
Rail-to-rail input/output make them ideal for driving sam-
pling A/D converters. In addition, excellent ac performance
makes them well-suited for audio applications. The class AB
output stage is capable of driving 600Ω loads connected to
any point between V+ and ground.
Rail-to-rail input and output swing significantly increases
dynamic range, especially in low-supply applications. Fig-
ure 1 shows the input and output waveforms for the
OPA343 in unity-gain configuration. Operation is from a
single +5V supply with a 10kΩ load connected to VS/2.
The input is a 5Vp-p sinusoid. Output voltage is approxi-
mately 4.98Vp-p.
Power-supply pins should be bypassed with 0.01µF ceramic
capacitors.
OPERATING VOLTAGE
OPA343 series op amps are fully specified from +2.7V to
+5V. However, supply voltage may range from +2.5V to
+5.5V. Parameters are guaranteed over the specified supply
range—a unique feature of the OPA343 series. In addition,
many specifications apply from –40°C to +85°C. Most
behavior remains virtually unchanged throughout the full
operating voltage range. Parameters which vary signifi-
cantly with operating voltages or temperature are shown in
the Typical Performance Curves.
RAIL-TO-RAIL INPUT
The input common-mode voltage range of the OPA343
series extends 500mV beyond the supply rails. This is
achieved with a complementary input stage—an N-channel
input differential pair in parallel with a P-channel differen-
tial pair, as shown in Figure 2. The N-channel pair is active
for input voltages close to the positive rail, typically (V+)
– 1.3V to 500mV above the positive supply. The P-channel
pair is on for inputs from 500mV below the negative supply
to approximately (V+) – 1.3V.
There is a small transition region, typically (V+) – 1.5V to
(V+) – 1.1V, in which both input pairs are on. This 400mV
transition region can vary ±300mV with process variation.
Thus, the transition region (both stages on) can range from
(V+) – 1.8V to (V+) – 1.4V on the low end, up to (V+)
– 1.2V to (V+) – 0.8V on the high end. Within the 400mV
transition region PSRR, CMRR, offset voltage, offset drift,
and THD may be degraded compared to operation outside
this region.
A double-folded cascode adds the signal from the two input
pairs and presents a differential signal to the class AB output
stage. Normally, input bias current is approximately 200fA,
however, input voltages exceeding the power supplies by

IOVERLOAD
more than 500mV can cause excessive current to flow in or
out of the input pins. Momentary voltages greater than
500mV beyond the power supply can be tolerated if the
current on the input pins is limited to 10mA. This is easily
accomplished with an input resistor, as shown in Figure 3.
Many input signals are inherently current-limited to less
than 10mA, therefore, a limiting resistor is not required.
capacitive load reacts with the op amp’s output resistance,
along with any additional load resistance, to create a pole in
the small-signal response which degrades the phase margin.
In unity gain, OPA343 series op amps perform well, with a
pure capacitive load up to approximately 1000pF. Increasing
gain enhances the amplifier’s ability to drive more capaci-
tance. See the typical performance curve “Small-Signal
Overshoot vs Capacitive Load.”
One method of improving capacitive load drive in the unity
gain configuration is to insert a 10Ω to 20Ω resistor in series
with the output, as shown in Figure 4. This significantly
reduces ringing with large capacitive loads. However, if
there is a resistive load in parallel with the capacitive load,
RS creates a voltage divider. This introduces a dc error at the
output and slightly reduces output swing. This error may be
insignificant. For instance, with RL = 10kΩ and RS = 20Ω,
there is only about a 0.2% error at the output.
DRIVING A/D CONVERTERS
OPA343 series op amps are optimized for driving medium
speed (up to 100kHz) sampling A/D converters. However,
they also offer excellent performance for higher-speed
converters. The OPA343 series provides an effective means
of buffering the A/D’s input capacitance and resulting
charge injection while providing signal gain. For applica-
tions requiring high accuracy, the OPA340 series is recom-
mended.
Figures 5 and 6 show the OPA343 driving an ADS7816.
The ADS7816 is a 12-bit, micro-power sampling converter
in the tiny MSOP-8 package. When used with the minia-
ture package options of the OPA343 series, the combina-
tion is ideal for space-limited and low-power applications.
For further information consult the ADS7816 data sheet.
With the OPA343 in a noninverting configuration, an RC
network at the amplifier’s output can be used to filter high
frequency noise in the signal (see Figure 5). In the invert-
ing configuration, filtering may be accomplished with a
capacitor across the feedback resistor (see Figure 6).
FIGURE 3. Input Current Protection for Voltages Exceeding
the Supply Voltage.
RAIL-TO-RAIL OUTPUT
A class AB output stage with common-source transistors is
used to achieve rail-to-rail output. For light resistive loads
(>50kΩ), the output voltage is typically a few millivolts
from the supply rails. With moderate resistive loads (2kΩ to
50kΩ), the output can swing to within a few tens of milli-
volts from the supply rails and maintain high open-loop
gain. See the typical performanc curve “Output Voltage
Swing vs Output Current.”
CAPACITIVE LOAD AND STABILITY
OPA343 series op amps can drive a wide range of capacitive
loads. However, all op amps under certain conditions may
become unstable. Op amp configuration, gain, and load
value are just a few of the factors to consider when determin-
ing stability. An op amp in unity gain configuration is the
most susceptible to the effects of capacitive load. The

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
