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 series is available in
multiple packages and offers low offset, drift, and low
quiescent current. The single, dual, and quad versions
all have identical specifications for maximum design
flexibility.
•
Supply range:
– Single-supply: 2.7 V to 36 V
– Dual-supply ±1.35 V to ±18 V
Low noise: 14 nV/√Hz at 1 kHz
Low offset drift: ±0.3 µV/°C (typical)
Input range includes negative supply
Input range operates to positive supply with
reduced performance

Unlike most op amps, which are specified at only one
supply voltage, the OPAx171-Q1 family of devices is
specified from 2.7 V to 36 V. Input signals beyond the
supply rails do not cause phase reversal.

Rail-to-rail output
Gain bandwidth: 3 MHz
Low quiescent current: 475 µA per amplifier
High Common-mode rejection: 120 dB (typical)
Low input bias current: 10 pA
Industry-Standard Package:
– 5-Pin Small-Outline Transistor SOT-23 (DBV)
Package
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.
