The OPA2171-EP is a 36-V, single-supply, low-noise operational amplifier with the ability to operate on supplies ranging from 2.7 V (±1.35 V) to 36 V (±18 V). These devices are available in micro-packages and offer low offset, drift, and bandwidth with low quiescent current. The single, dual, and quad versions all have identical specifications for maximum design flexibility.
Unlike most operational amplifiers, which are specified at only one supply voltage, the OPA2171-EP is specified from 2.7 to 36 V. Input signals beyond the supply rails do not cause phase reversal. The OPA2171-EP is stable with capacitive loads up to 300 pF. The input can operate 100 mV below the negative rail and within 2 V of the top rail during normal operation. Note that these devices can operate with full rail-to-rail input 100 mV beyond the top rail, but with reduced performance within 2 V of the top rail.
The OPA2171-EP operational amplifier is specified from -55°C to 125°C.
