Analog Devices AD629 High Common-Mode Voltage Difference Amplifier Datasheet
The AD629 is a precision unity gain differential-to-single-ended amplifier capable of rejecting extremely high common-mode signals exceeding 270 V. It features an internal resistor network and operational amplifier to provide accurate measurements while protecting inputs from transients up to ±500 V.
The device operates over a wide supply voltage range of ±2.5 V to ±18 V and is available in 8-lead Plastic DIP (N) and SOIC (R) packages. It offers excellent DC performance with low offset drift and high accuracy, making it suitable for applications such as battery cell monitoring and motor control isolation.
