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 (+VS – 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.
