91911-31151 vs OPA2171AIDCUT vs OPA2171AIDCUR Comparison

51 Position Connector Header, Center Strip Contacts Surface Mount Gold or Gold, GXT™

The OPA2171AIDCUT is a dual low noise Operational Amplifier features low quiescent current, low offset, drift and bandwidth. The dual 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 2.7 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. 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.

The OPA171, OPA2171, and OPA4171 (OPAx171) are a family of 36-V, single-supply, low-noise operational amplifiers 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 OPAx171 family is specified from 2.7 to 36 V. Input signals beyond the supply rails do not cause phase reversal. The OPAx171 family 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. 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 OPAx171 series of operational amplifiers are specified from –40°C to 125°C.
