Product Summary

The AD629ARZ-RL 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. The AD629ARZ-RL can replace costly isolation amplifiers in applications that do not require galvanic isolation. The device operates 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. The applications of the AD629ARZ-RL include: High voltage current sensing, Battery cell voltage monitors, Power supply current monitors, Motor controls, Isolation.
