Single, dual, and quad versions are offered in a variety of packages. While the quiescent current is less than 200µA per amplifier, the OPA705 still offers excellent dynamic performance (1MHz GBW and 0.6V/µs SR) and unity-gain stability. The OPA705 series is 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 version (OPA705) is available in the MicroSIZE SOT23-5 and in the standard SO-8 surface-mount packages. The dual version (OPA2705) is available in the MSOP-8, SO-8, and DIP-8 packages. The quad OPA4705 is 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.

OPA705 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 OPA705 is unity-gain stable and offers 1MHz bandwidth and 0.6V/µs slew rate. OPERATING VOLTAGE OPA705 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 Characteristics. 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 OPA705 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 OPA705 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. 8 OPA705, 2705, 4705 SBOS182A 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 OPA705 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 OPA705 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”). +V IOVERLOAD 10mA max 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”). VOUT OPA705 VIN R V– 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. FIGURE 3. Input Current Protection for Voltages Exceeding the Supply Voltage.

Figure 6 shows the OPA2705 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 space-limited applications. 9 NC 48 NC 47 NC 46 NC 45 VOUTA Sense 44 VOUTA 43 VREFL AB Sense 42 VREFL AB 41 VREFH AB 40 VREFH AB Sense 39 DAC7644 VOUTB Sense 38 VOUTB 37 +V V– VOUT –2.5V 1/2 OPA2705 Ref Negative Reference 500pF V+ 500pF 1/2 OPA2705 VOUT +2.5V Ref Positive Reference –V FIGURE 6.
