3 Description
The OPA2171-EP is a 36-V, single-supply, low-noise
operational amplifier 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 OPA2171-
EP is specified from 2.7 to 36 V. Input signals beyond
the supply rails do not cause phase reversal. The
OPA2171-EP 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. Note that 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 OPA2171-EP operational amplifier is specified
from –55°C to 125°C.
