GENERAL DESCRIPTION

The OP497 is a quad op amp with precision performance in

the space-saving, industry standard 16-lead SOlC package.

Its combination of exceptional precision with low power and

extremely low input bias current makes the quad OP497 useful

in a wide variety of applications.

Precision performance of the OP497 includes very low offset

(<50 μV) and low drift (<0.5 μV/°C). Open-loop gain exceeds

2000 V/mV ensuring high linearity in every application. Errors

due to common-mode signals are eliminated by its common-

mode rejection of >120 dB. The OP497 has a power supply

rejection of >120 dB which minimizes offset voltage changes

experienced in battery-powered systems. The supply current

of the OP497 is <625 μA per amplifier, and it can operate with

supply voltages as low as ±2 V.

The OP497 uses a superbeta input stage with bias current

cancellation to maintain picoamp bias currents at all temperatures.

This is in contrast to FET input op amps whose bias currents

start in the picoamp range at 25°C but double for every 10°C

rise in temperature to reach the nanoamp range above 85°C.

The input bias current of the OP497 is <100 pA at 25°C.
