GENERAL DESCRIPTION  
HIGH ACCURACY DC PERFORMANCE  
3 ppm maximum gain nonlinearity (AD629B)  
20 μV/°C maximum offset drift (AD629A)  
10 μV/°C maximum offset drift (AD629B)  
10 ppm/°C maximum gain drift  
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 ±2ꢀ7 .  
The AD629 can replace costly isolation amplifiers in  
applications that do not require galvanic isolation. The device  
operates over a ±2ꢀ7 ꢁ common-mode voltage range and has  
inputs that are protected from common-mode or differential  
mode transients up to ±±77 .  
EXCELLENT AC SPECIFICATIONS  
77 dB minimum CMRR @ ±00 Hz (AD629A)  
86 dB minimum CMRR @ ±00 Hz (AD629B)  
±00 kHz bandwidth  
The AD629 has low offset, low offset drift, low gain error drift,  
low common-mode rejection drift, and excellent CMRR over a  
wide frequency range.  
APPLICATIONS  
High voltage current sensing  
Battery cell voltage monitors  
Power supply current monitors  
Motor controls  
The AD629 is available in low cost, 8-lead PDIP and 8-lead  
SOIC packages. For all packages and grades, performance is  
guaranteed over the industrial temperature range of −47°C to  
+8±°C.
