DESCRIPTION
The OPA171-Q1 is a 36V, single-supply, low-noise
operational amplifier with the ability to operate on
supplies ranging from +2.7V (±1.35V) to +36V
(±18V). This device is 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 op amps, which are specified at only one
supply voltage, the OPA171-Q1 is specified from
+2.7V to +36V. Input signals beyond the supply rails
do not cause phase reversal. The OPA171-Q1 is
stable with capacitive loads up to 300pF. The input
can operate 100mV below the negative rail and within
2V of the top rail during normal operation. Note that
these devices can operate with full rail-to-rail input
100mV beyond the top rail, but with reduced
performance within 2V of the top rail.
The OPA171-Q1 op amp is specified from –40°C to
+125°C.
