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. NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only. Functional operation of the device at these conditions, or beyond the specified operating conditions, is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package.

Within the 200mV transition region PSRR, CMRR, offset voltage, offset drift, and THD may be degraded compared to operation outside this region. The OPA348 series 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 OPA348 in unity-gain configuration. Operation is from a single +5V supply with a 100k load connected to VS /2. The input is a 5Vp-p sinusoid. Output voltage is approximately 4.98Vp-p. G = +1V/V, VS = +5V 2 1.5 Offset Voltage (mV) Power-supply pins should be bypassed with 0.01F ceramic capacitors.

Behavior of Typical Transition Region at Room Temperature. 0V 20s/div RAIL-TO-RAIL INPUT FIGURE 1. The OPA348 Features Rail-to-Rail Input/Output. OPERATING VOLTAGE OPA348 series op amps are fully specified and tested from +2.5V to +5.5V. However, supply voltage may range from +2.1V to +5.5V. Parameters are tested over the specified supply range--a unique feature of the OPA348 series. 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. The input common-mode range extends from (V-) - 0.2V to (V+) + 0.2V. For normal operation, inputs should be limited to this range. The absolute maximum input voltage is 500mV beyond the supplies. Inputs greater than the input commonmode range but less than the maximum input voltage, while not valid, will 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 COMMON-MODE VOLTAGE RANGE 5V VOUT 1V/div The input common-mode voltage range of the OPA348 series extends 200mV 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+) - 1.2V to 300mV above the positive supply, while the P-channel pair is on for inputs from 300mV below the negative supply to approximately (V+) - 1.4V. There is a small transition region, typically (V+) - 1.4V to (V+) - 1.2V, in which both pairs are on. This 200mV transition region, shown in Figure 2, can vary 300mV with process variation. Thus, the transition region (both stages on) can range from (V+) - 1.7V to (V+) - 1.5V on the low end, up to (V+) - 1.1V to (V+) - 0.9V 0V 10s/div FIGURE 3. OPA348--No Phase Inversion with Inputs Greater than the Power-Supply Voltage. OPA348, 2348, 4348 SBOS213 G = +1V/V, VS = +5V www.ti.com 7 Normally, input currents are 0.5pA. However, large inputs (greater than 500mV 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 10mA. This is easily accomplished with an input voltage resistor, as shown in Figure 4. +5V IOVERLOAD 10mA max VOUT OPA348 VIN 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 500pF load, reducing the resistor values from 100k to 5k 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 (4pF to 6pF) 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. 5k FIGURE 4. Input Current Protection for Voltages Exceeding the Supply Voltage. CFB RF 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 5k loads connected to any potential between V+ and ground. For light resistive loads (> 100k), the output voltage can typically swing to within 18mV from supply rail. With moderate resistive loads (10k to 50k), the output voltage can typically swing to within 100mV 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 OPA348 in a unity-gain configuration can directly drive up to 250pF 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 VOUT OPA348 VIN 10 to 20 RL CL RI VIN VOUT OPA348 CIN CL FIGURE 6. Improving Capacitive Load Drive. DRIVING A/D CONVERTERS The OPA348 series op amps are optimized for driving medium-speed sampling Analog-to-Digital Converters (ADCs). The OPA348 op amps buffer the ADCs input capacitance and resulting charge injection while providing signal gain. The OPA348 in a basic noninverting configuration driving the ADS7822, see Figure 7. 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, lowpower applications. In this configuration, an RC network at the ADC's input can be used to provide for anti-aliasing filter and charge injection current. The OPA348 in noninverting configuration driving ADS7822 limited, low-power applications. In this configuration, an RC network at the ADC's input can be used to provide for antialiasing filter and charge injection current. See Figure 8 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 will operate with VS = 2.7V to 5V with less than 250A typical quiescent current. FIGURE 5.
