The OPA171, OPA2171, and OPA4171 (OPAx171) are a series of low-noise, 36-V single-supply operational amplifiers that can run on supplies ranging from 2.7 V (1.355 V) to 36 V (18V). These micro-packaged devices have low offset, drift, and bandwidth, as well as a low quiescent current. For optimum design flexibility, the single, twin, and quad versions all share the same specs.
Unlike other operational amplifiers, which have a single supply voltage specification, the OPA171AIDBVT has a supply voltage range of 2.7 to 36 V. Phase reversal is not caused by input signals that extend beyond the supply rails. With capacitive loads up to 300 pF, the OPA171AIDBVT is stable. During typical operation, the input can function 100 mV below the negative rail and within 2 V of the top rail. These devices can work with full rail-to-rail input up to 100 mV beyond the top rail, however, performance is degraded below 2 V.
