The OPA171AID is a single low power general purpose Operational Amplifier features low quiescent current, low offset, drift and bandwidth. The single version has identical specifications for maximum design flexibility. Unlike most operational amplifier, which is specified at only one supply voltage, the OPAx171 family is specified from ±1.35 to ±18V. Input signal beyond the supply rails do not cause phase reversal. The OPAx171 family is stable with capacitive loads up to 300pF. The input can operate 100mV below the negative rail and within 2V of the top rail during normal operation. This device can operate with full rail-to-rail input 100mV beyond the top rail, but with reduced performance within 2V of the top rail.
