GENERAL DESCRIPTION  
The AD8276/AD8277 are general-purpose, unity-gain difference  
amplifiers intended for precision signal conditioning in power  
critical applications that require both high performance and low  
power. They provide exceptional common-mode rejection ratio  
(86 dB) and high bandwidth while amplifying signals well beyond  
the supply rails. The on-chip resistors are laser-trimmed for  
excellent gain accuracy and high CMRR. They also have extremely  
low gain drift vs. temperature.

The common-mode range of the amplifiers extends to almost  
double the supply voltage, making these amplifiers ideal for single-  
supply applications that require a high common-mode voltage  
range. The internal resistors and ESD circuitry at the inputs also  
provide overvoltage protection to the op amps.

The AD8276/AD8277 are unity-gain stable. While they are  
optimized for use as difference amplifiers, they can also be  
connected in high precision, single-ended configurations with  
G = −1, +1, +2. The AD8276/AD8277 provide an integrated  
precision solution that has smaller size, lower cost, and better  
performance than a discrete alternative.

1 U = unidirectional, B = bidirectional.  
The AD8276 is available in the space-saving 8-lead MSOP and  
SOIC packages, and the AD8277 is offered in a 14-lead SOIC  
package. Both are specified for performance over the industrial  
temperature range of −40°C to +85°C and are fully RoHS  
compliant.  
The AD8276/AD8277 operate on single supplies (2.0 V to 36 V)  
or dual supplies ( 2 V to 18 V). The maximum quiescent  
supply current is 200 μA per channel, which is ideal for battery-  
operated and portable systems.
