The OPA171-Q1 family of devices is a 36-V, single-supply, low-noise operational amplifier
(op amp) with the ability to operate on supplies ranging from 2.7 V (±1.35 V) to 36 V (±18 V). This
device is available in micro-packages and offers low offset, drift, and bandwidth with low
quiescent current. The single, dual, and quad versions all have identical specifications for
maximum design flexibility.
For all available packages, see the orderable addendum at the
end of the datasheet.

Unlike most op amps, which are specified at only one supply voltage, the OPAx171-Q1
family of devices is specified from 2.7 to 36 V. Input signals beyond the supply rails do not cause
phase reversal. The OPAx171-Q1 family of devices 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. The device 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-Q1 op amp is specified from –40°C to +125°C.
