DESCRIPTION
The OPA171, OPA2171 and OPA4171 (OPAx171)
are a family of 36V, single-supply, low-noise
operational amplifiers with the ability to operate on
supplies ranging from +2.7V (±1.35V) to +36V
(±18V). 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 op amps, which are specified at only one
supply voltage, the OPAx171 family is specified from
+2.7V to +36V. Input signals beyond the supply rails
do not cause phase reversal. The OPAx171 family 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 OPAx171 series of op amps are specified
from –40°C to +125°C.
