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.
