3 Description
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.
