Power-supply rejection ratio (PSRR), common-mode rejection ratio (CMRR), and open-loop gain (AOL) typical values are 100dB or better. When designing for ultra-low power, choose system components carefully. To minimize current consumption, select large-value resistors. Any resistors will react with stray capacitance in the circuit and the input capacitance of the operational amplifier. These parasitic RC combinations can affect the stability of the overall system. A feedback capacitor may be required to assure stability and limit overshoot or gain peaking. Good layout practice mandates the use of a 0.1µF bypass capacitor placed closely across the supply pins. OPERATING VOLTAGE OPA379 series op amps are fully specified and tested from +1.8V to +5.5V. Parameters that vary significantly with supply voltage are shown in the Typical Characteristics curves. INPUT COMMON-MODE VOLTAGE RANGE The input common-mode voltage range of the OPA379 family typically extends 100mV beyond each supply rail. This rail-to-rail input is achieved using a complementary input stage. CMRR is specified from the negative rail to 1V below the positive rail. Between (V+) − 1V and (V+) + 0.1V, the amplifier operates with higher offset voltage because of the transition region of the input stage. See the typical characteristic, Offset Voltage vs Common-Mode Voltage. PROTECTING INPUTS FROM OVER-VOLTAGE Normally, input currents are 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 limiting is easily accomplished with an input voltage resistor, as shown in Figure 1. I OVERLOAD 10mA max OPA379 VOUT VIN 5kΩ Figure 1. Input Current Protection for Voltages Exceeding the Supply Voltage NOISE Although micropower amplifiers frequently have high wideband noise, the OPA379 series offer excellent noise performance. Resistors should be chosen carefully because the OPA379 has only 2.8µVPP of 0.1Hz to 10Hz noise, and 80nV/√Hz of wideband noise; otherwise, they can become the dominant source of noise. CAPACITIVE LOAD AND STABILITY Follower configurations with load capacitance in excess of 30pF can produce extra overshoot (see typical characteristic, Small-Signal Overshoot vs Capacitive Load) and ringing in the output signal. Increasing the gain enhances the ability of the amplifier to drive greater capacitive loads. In unity-gain configurations, capacitive load drive can be improved by inserting a small (10Ω to 20Ω) resistor, RS, in series with the output, as shown in Figure 2. This resistor 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 OPA379 VIN 10Ω to 20Ω RL CL Figure 2. Series Resistor in Unity-Gain Buffer Configuration Improves Capacitive Load Drive 7 "#$ %"#$ &"#$ www.ti.com SBOS347A − NOVEMBER 2005 − REVISED DECEMBER 2005 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 smaller valued resistors. 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 3. This configuration significantly reduces overshoot by compensating the effect of capacitance, CIN, which includes the amplifier input capacitance and PC board parasitic capacitance. 1.

Figure 5 shows the OPA379 monitoring the current in a power-supply return path using a 0.1Ω shunt resistor. The NPN transistor, Q1 (2N2222 or equivalent) is used to generate equal voltages at the inverting and noninverting inputs. Therefore, the voltage drops across R1 and RS are equal, and the current flowing through Q1 is directly proportional to the current flowing through RS. As the load current increases, the current through Q1 increases, the voltage drop across R2 increases, and this decreases the output voltage, VOUT, as shown in Equation (5): Figure 6 shows the OPA2379 used as a window comparator. The threshold limits are set by VH and VL, with VH > VL . When VIN < VH, the output of A1 will be low. When VIN >VL, the output of A2 will be low. Therefore, both op amp outputs will be at 0V as long as VIN is between VH and VL. This results in no current flowing through either diode, Q1 in cutoff, with the base voltage at 0V, and VOUT forced high.
