This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
OPA2348 op amps are unity-gain stable and suitable for a wide range of general-purpose applications.
The OPA2348 features wide bandwidth and unity-gain stability with rail-to-rail input and output for increased
dynamic range. Figure 1 shows the input and output waveforms for the OPA2348 in unity-gain configuration.
Operation is from a single 5-V supply with a 100-kΩload connected to VS/2. The input is a 5-VPP sinusoid.
Output voltage is approximately 4.98 VPP.
Power-supply pins should be bypassed with 0.01-µF ceramic capacitors.
Figure 1. Rail-to-Rail Input/Output
Operating Voltage
OPA2348 op amps are fully specified and tested from 2.5 V to 5.5 V. However, supply voltage may range from
2.1 V to 5.5 V. Parameters are tested over the specified supply range, a unique feature of the OPA2348. In
addition, all temperature specifications apply from –40°C to 125°C. Most behavior remains virtually unchanged
throughout the full operating voltage range. Parameters that vary significantly with operating voltages or
temperature are shown in the Typical Characteristics.
Common-Mode Voltage Range
The input common-mode voltage range of the OPA2348 extends 200 mV beyond the supply rails. This is
achieved with a complementary input stage—an N-channel input differential pair in parallel with a P-channel
differential pair. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.2 V to
300 mV above the positive supply, while the P-channel pair is on for inputs from 300 mV below the negative
supply to approximately (V+) – 1.4 V. There is a small transition region, typically (V+) – 1.4 V to (V+) – 1.2 V, in
which both pairs are on. This 200-mV transition region, shown in Figure 2, can vary ±300 mV with process
variation. Thus, the transition region (both stages on) can range from (V+) – 1.7 V to (V+) – 1.5 V on the low end,
up to (V+) – 1.1 V to (V+) – 0.9 V on the high end. Within the 200-mV transition region, PSRR, CMRR, offset
voltage, offset drift, and THD may be degraded compared to operation outside this region.

Figure 2. Behavior of Typical Transition Region at Room Temperature
Rail-to-Rail Input
The input common-mode range extends from (V–) – 0.2 V to (V+) + 0.2 V. For normal operation, inputs should
be limited to this range. The absolute maximum input voltage is 500 mV beyond the supplies. Inputs greater than
the input common-mode range but less than the maximum input voltage, while not valid, do not cause any
damage to the op amp. Unlike some other op amps, if input current is limited the inputs may go beyond the
power supplies without phase inversion, as shown in Figure 3.
Figure 3. No Phase Inversion With Inputs Greater Than Power-Supply Voltage
Normally, input currents are 0.5 pA. However, large inputs (greater than 500 mV beyond the supply rails) can
cause excessive current to flow in or out of the input pins. Therefore, as well as keeping the input voltage below
the maximum rating, it is also important to limit the input current to less than 10 mA. This is easily accomplished
with an input voltage resistor, as shown in Figure 4.

Rail-to-Rail Output
A class AB output stage with common-source transistors is used to achieve rail-to-rail output. This output stage is
capable of driving 5-kΩloads connected to any potential between V+ and ground. For light resistive loads
(>100 kΩ), the output voltage can typically swing to within 18 mV from supply rail. With moderate resistive loads
(10 kΩto 50 kΩ), the output voltage can typically swing to within 100 mV of the supply rails while maintaining
high open-loop gain (see the typical characteristic "Output Voltage Swing vs Output Current").
Capacitive Load and Stability
The OPA2348 in a unity-gain configuration can directly drive up to 250-pF pure capacitive load. Increasing the
gain enhances the amplifier’s ability to drive greater capacitive loads (see the typical characteristic "Small-Signal
Overshoot vs Capacitive Load"). In unity-gain configurations, capacitive load drive can be improved by inserting a
small (10 Ωto 20 Ω) resistor, RS, in series with the output, as shown in Figure 5. This significantly reduces
ringing while maintaining dc performance for purely capacitive loads. However, if there is a resistive load in
parallel with the capacitive load, a voltage divider is created, introducing a direct current (dc) error at the output
and slightly reducing the output swing. The error introduced is proportional to the ratio RS/RLand is generally
negligible.
Figure 5. Series Resistor in Unity-Gain Buffer Configuration Improves Capacitive Load Drive
In unity-gain inverter configuration, phase margin can be reduced by the reaction between the capacitance at the
op amp input and the gain setting resistors, thus degrading capacitive load drive. Best performance is achieved
by using small-valued resistors. For example, when driving a 500-pF load, reducing the resistor values from
100 kΩto 5 kΩdecreases overshoot from 55% to 13% (see the typical characteristic "Small-Signal Overshoot
vs. Load Capacitance"). However, when large valued resistors cannot be avoided, a small (4 pF to 6 pF)
capacitor, CFB, can be inserted in the feedback, as shown in Figure 6. This significantly reduces overshoot by
compensating the effect of capacitance, CIN, which includes the amplifier's input capacitance and PC board
parasitic capacitance.

Driving Analog-to-Digital Converters (ADCs)
The OPA2348 op amps are optimized for driving medium-speed sampling ADCs. The OPA2348 op amps buffer
the ADC input capacitance and resulting charge injection while providing signal gain.
Figure 7 shows the OPA2348 in a basic noninverting configuration driving the ADS7822. The ADS7822 is a
12-bit, micropower sampling converter in the MSOP-8 package. When used with the low-power miniature
packages of the OPA348, the combination is ideal for space-limited, low-power applications. In this configuration,
an RC network at the ADC input can be used to provide for anti-aliasing filter and charge injection current.
Figure 7. Noninverting Configuration Driving ADS7822
The OPA2348 can also be used in noninverting configuration driving ADS7822 in limited low-power applications.
In this configuration, an RC network at the ADC input can be used to provide for antialiasing filter and charge
injection current. See Figure 7 for the OPA2348 driving an ADS7822 in a speech bandpass filtered data
acquisition system. This small low-cost solution provides the necessary amplification and signal conditioning to
interface directly with an electret microphone. This circuit operates with VS= 2.7 V to 5 V with less than 250-µA
typical quiescent current.

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.
