Single, dual, and quad versions are offered in a variety of packages. While the quiescent current is less than 200µA per amplifier, the OPA703 still offers excellent dynamic performance (1MHz GBW and 0.6V/µs SR) and unity-gain stability. The OPA704 is optimized for gains of 5 or greater and provides 3MHz GBW and 3V/µs slew rate. The OPA703 and OPA704 series are fully specified and guaranteed over the supply range of ±2V to ±6V. Input swing extends 300mV beyond the rail and the output swings to within 40mV of the rail. The single versions (OPA703 and OPA704) are available in the MicroSIZE SOT23-5 and in the standard SO-8 surfacemount, as well as the DIP-8 packages. Dual versions (OPA2703 and OPA2704) are available in the MSOP-8, SO-8, and DIP-8 packages. The quad OPA4703 and OPA4704 are available in the TSSOP-14 and SO-14 packages. All are specified for operation from –40°C to +85°C.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. (2) Input terminals are diode-clamped to the power supply rails. Input signals that can swing more than 0.3V beyond the supply rails should be current-limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package. 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.

OPA703 and OPA704 series op amps can operate on 160µA quiescent current from a single (or split) supply in the range of 4V to 12V (±2V to ±6V), making them highly versatile and easy to use. The OPA703 is unity-gain stable and offers 1MHz bandwidth and 0.6V/µs slew rate. The OPA704 is optimized for gains of 5 or greater with a 3MHz bandwidth and 3V/µs slew rate. OPERATING VOLTAGE OPA703 and OPA704 series op amps are fully specified and guaranteed from +4V to +12V over a temperature range of –40ºC to +85ºC. Parameters that vary significantly with operating voltages or temperature are shown in the Typical Performance Curves. Rail-to-rail input and output swing helps maintain dynamic range, especially in low supply applications. Figure 1 shows the input and output waveforms for the OPA703 in unitygain configuration. Operation is from a ±5V supply with a 100kΩ load connected to VS /2. The input is a 10Vp-p sinusoid. Output voltage is approximately 10Vp-p. RAIL-TO-RAIL INPUT The input common-mode voltage range of the OPA703 series extends 300mV beyond the supply rails at room temperature. This is achieved with a complementary input stage—an Nchannel input differential pair in parallel with a P-channel differential pair, as shown in Figure 2. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 2.0V to 300mV above the positive supply, while the Pchannel pair is on for inputs from 300mV below the negative supply to approximately (V+) – 1.5V. There is a small transition region, typically (V+) – 2.0V to (V+) – 1.5V, in which both pairs are on. This 500mV transition region can vary ±100mV with process variation. Thus, the transition region (both stages on) can range from (V+) – 2.1V to (V+) – 1.4V on the low end, up to (V+) – 1.9V to (V+) – 1.6V on the high end. Within the 500mV transition region PSRR, CMRR, offset voltage, and offset drift, and THD may vary compared to operation outside this region.

Simplified Schematic. 10 OPA703, OPA704 SBOS180A INPUT VOLTAGE Device inputs are protected by ESD diodes that will conduct if the input voltages exceed the power supplies by more than approximately 300mV. Momentary voltages greater than 300mV beyond the power supply can be tolerated if the current 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 always required. The OPA703 features no phase inversion when the inputs extend beyond supplies if the input current is limited, as seen in Figure 4. CAPACITIVE LOAD AND STABILITY The OPA703 and OPA704 series op amps can drive up to 1000pF pure capacitive load. Increasing the gain enhances the amplifier’s ability to drive greater capacitive loads (see the typical performance curve “Small Signal Overshoot vs Capacitive Load”). One method of improving capacitive load drive in the unitygain configuration is to insert a 10Ω to 20Ω resistor inside the feedback loop, as shown in Figure 5. This reduces ringing with large capacitive loads while maintaining DC accuracy. +V IOVERLOAD 10mA max RS 20Ω OPA703 VOUT OPA703 VOUT VIN CL VIN RL R V– FIGURE 3.

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 1kΩ loads connected to any point between V+ and ground. For light resistive loads (> 100kΩ), the output voltage can swing to 40mV from the supply rail. With moderate resistive loads (20kΩ), the output can swing to within 75mV from the supply rails while maintaining high open-loop gain (see the typical performance curve “Output Voltage Swing vs Output Current”). OPA703, OPA704 SBOS180A FIGURE 5. Series Resistor in Unity-Gain Buffer Configuration Improves Capacitive Load Drive. APPLICATION CIRCUITS Figure 6 shows a G = 5 non-inverting amplifier implemented with the OPA703 and OPA704 op amps. It demonstrates the increased speed characteristics (bandwidth, slew rate and settling time) that can be achieved with the OPA704 family when used in gains of five or greater. Some optimization of feedback capacitor value may be required to achieve best dynamic response. Circuits with closed-loop gains of less than five should use the OPA703 family for good stability and capacitive load drive. The OPA703 can be used in gains greater than five, but will not provide the increased speed benefits of the OPA704 family. The OPA703 series op amps are optimized for driving medium-speed sampling data converters. The OPA703 op amps buffer the converter’s input capacitance and resulting charge injection while providing signal gain. Figure 7 shows the OPA2703 in a dual-supply buffered reference configuration for the DAC7644. The DAC7644 is a 16-bit, low-power, quad-voltage output converter. Small size makes the combination ideal for automatic test equipment, data acquisition systems, and other low-power spacelimited applications. 11 3pF 5kΩ 20kΩ 5kΩ OPA703 20kΩ OPA704 G=5 VIN G=5 VIN LARGE-SIGNAL RESPONSE Demonstrates speed improvement that can be achieved with OPA704 family in applications with G ≥ 5. 2V/div OPA703 OPA704 5µs/div FIGURE 6.
