Description
The OPA170, OPA2170, and OPA4170 devices (OPAx170) are a family of 36-V, single-supply, low-noise operational amplifiers (op amps) that feature micro packages with the ability to operate on supplies ranging from 2.7 V (±1.35 V) to 36 V (±18 V). They offer good 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 OPAx170 family of op amps is specified from 2.7 V to 36 V. Input signals beyond the supply rails do not cause phase reversal. The OPAx170 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 positive rail for normal operation. Note that these devices can operate with full rail-to-rail input 100 mV beyond the positive rail, but with reduced performance within 2 V of the positive rail. The OPAx170 op amps are specified from –40°C to +125°C.
