GENERAL DESCRIPTION

The MAX74810 is a dual-channel, zero drift op amp with

low noise and power, ground sensing inputs, and rail-

to-rail output, optimized for total accuracy over time,

temperature, and voltage conditions. The wide

operating voltage and temperature ranges, as well as

the high open-loop gain and very low DC and AC errors,

make the devices suitable for amplifying very small

input signals and for accurately reproducing larger

signals in a wide variety of applications.

The MAX74810 performance is specified at 5.0V and 50V

power supply voltages. These devices operate over the

range of 4.5V to 50V, and are excellent for applications

using single-ended supplies of 5V, 10V, 12V, and 30V, or

for applications using higher single supplies and dual

supplies of ±2.5V, ±5V, and ±15V. The MAX74810 uses

on-chip filtering to achieve high immunity to

electromagnetic interference (EMI).

The MAX74810 is fully specified over the extended

industrial temperature range of −40°C to +125°C and is

available in an 8-lead MSOP package.
