The OPA170 is a 36-V, single-supply, low-noise operational amplifier that features a micro package with the ability to operate on supplies ranging from +2.7V (±1.35V) to +36V (±18V). It offers good offset, drift, and bandwidth with low quiescent current. Unlike most op amps, which are specified at only one supply voltage, the OPA170 is specified from +2.7V to +36V. Input signals beyond the supply rails do not cause phase reversal. The OPA170 is stable with capacitive loads up to 300pF. The input can operate 100mV below the negative rail and within 2V of the positive rail for normal operation. Note that these devices can operate with full rail-to-rail input 100mV beyond the positive rail, but with reduced performance within 2V of the positive rail. The OPA170 is available in the SOT553-5 package and is specified from –40°C to +150°C.
