JANUARY 2009 - REVISED MARCH 2010 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-k load 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-F ceramic capacitors. G = +1V/V, VS = +5V Output (Inverted on Scope) 1V/div 5V 0V 20s/div 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 -40C to 125C. 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.

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. VIN G = +1V/V, V S = +5V 5V 1V/div VOUT 0V 10s/div 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. +5V IOVERLOAD 10mA max 1/2 OPA2348 VOUT VIN 5kW Figure 4.

This output stage is capable of driving 5-k loads connected to any potential between V+ and ground. For light resistive loads (>100 k), the output voltage can typically swing to within 18 mV from supply rail. With moderate resistive loads (10 k to 50 k), 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 to 20 ) 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/RL and is generally negligible. V+ RS 1/2 OPA2348 VOUT 10W to 20W VIN RL CL 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 k to 5 k decreases 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.

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.

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.
