APPLICATIONS

Current Sensing

Interface for Pressure Transducers, Position Indicators,

Strain Gages, and Other Low Level Signal Sources

The amplifier’s inputs are protected against continuous overload

of up to 50 V, and RFI filters are included in the attenuator

network. The output range is +0.03 V to +4.9 V using a +5 V

supply. The amplifier provides a preset gain of 10, but gains be-

tween 10 to 100 can be easily configured with an external resis-

tor. Furthermore, a gain of 100 is available by connecting the G

= 100 pin to analog ground. The AD626 also offers low-pass

filter capability by connecting a capacitor between the filter pin

and analog ground.

PRODUCT DESCRIPTION

The AD626 is a low cost, true single supply differential ampli-

fier designed for amplifying and low-pass filtering small differen-

tial voltages from sources having a large common-mode voltage.

The AD626 can operate from either a single supply of +2.4 V to

+10 V, or dual supplies of ±1.2 V to ±6 V. The input common-

mode range of this amplifier is equal to 6 (+V_S– 1 V) which

provides a +24 V CMR while operating from a +5 V supply.

Furthermore, the AD626 features a CMR of 90 dB typ.

The AD626A and AD626B operate over the industrial tempera-

ture range of –40°C to +85°C. The AD626 is available in two

8-lead packages: a plastic mini-DIP and SOIC.
