The OPA2172ID is a dual low noise Operational Amplifier with rail-to-rail output. The single-supply operational amplifier offers low offset, drift and quiescent current. This device also offers wide bandwidth, fast slew rate and high output current drive capability. The dual version has identical specifications for maximum design flexibility. Unlike most op amps, which is specified at only one supply voltage, the OPAx172 family is specified from +4.5 to +36V. Input signals beyond the supply rails do not cause phase reversal. The input can operate 100mV below the negative rail and within 2V of the top rail during normal operation.
