DESCRIPTION

The AO1317 is single micro-power, low-voltage,

zero-drift CMOS operational amplifiers. Feature

rail-to-rail input and output swings and low quiescent

current (25uA, typ. at 5V) combined with a wide

gain-bandwidth product of 350kHz and very low noise

(70nV/ Hz at 1kHz) makes AO1317 very attractive

for a variety of battery-power applications.

The AO1317 amplifiers offer impressive bandwidth

(350kHz), zero-drift over temperature, low bias

current (20pA), very low offset voltage (10μV max)

makes AO1317 to be a perfect choice for low offset,

low power consumption and high impedance

applications.

The AO1317 provides RF/EMI rejection filter, high

electrostatic discharge (ESD) protection (6-kV HBM)

and excellent CMRR without the crossover

associated with traditional complementary input

stages further to superior performance for driving

analog-to-digital converters (ADCs) without

degradation of differential linearity.

The AO1317 is optimized for operation at voltages as

low as +1.8V and up to +5.5V and are specified over

the extended industrial temperature range (-40℃ to

+125℃).

The AO1317 is available in SOT-25 and SC70-5

packages.
