GENERAL DESCRIPTION  
The AD629 is a difference amplifier with a very high input  
common-mode voltage range. It is a precision device that  
allows the user to accurately measure differential signals in the  
presence of high common-mode voltages up to 270 V.  
EXCELLENT AC SPECIFICATIONS  
77 dB Min CMRR @ 500 Hz (AD629A)  
86 dB Min CMRR @ 500 Hz (AD629B)  
500 kHz Bandwidth  
The AD629 can replace costly isolation amplifiers in applications  
that do not require galvanic isolation. The device will operate  
over a 270 V common-mode voltage range and has inputs  
that are protected from common-mode or differential mode  
transients up to 500 V.  
APPLICATIONS  
High Voltage Current Sensing  
Battery Cell Voltage Monitor  
Power Supply Current Monitor  
Motor Control  
The AD629 has low offset, low offset drift, low gain error drift,  
as well as low common-mode rejection drift, and excellent CMRR  
over a wide frequency range.  
Isolation  
The AD629 is available in low-cost, plastic 8-lead DIP and  
SOIC packages. For all packages and grades, performance is  
guaranteed over the entire industrial temperature range from  
–40°C to +85°C.
