3 Description
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.
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.
