OPA2171 采用微型封装的 36V 通用低功耗 RRO 运算放大器
The OPA171, OPA2171 and OPA4171 (OPAx171) are a family of 36V, single-supply, low-noise operational amplifiers with the ability to operate on supplies ranging from +2.7V (±1.35V) to +36V (±18V). 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 op amps, which are specified at only one supply voltage, the OPAx171 family is specified from +2.7V to +36V. Input signals 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
