The AD629 is a differential amplifier with a very high input common-mode voltage range. It is a precision device that allows users to accurately measure differential signals at high common-mode voltages of up to ±270v. The AD629 can replace expensive isolation amplifiers in applications that do not require electrical isolation.
The device operates in the common-mode voltage range of ±270v and has inputs that protect common-mode or differential mode transients up to ±500v. The AD629 features low bias, low bias drift, low gain error drift, low common-mode suppression drift, and excellent CMRR over a wide frequency range.
The AD629 is available in die and package form in 8-pin PDIP and 8-pin SOIC packages. Performance is guaranteed in the industrial temperature range −40°C to +85°C for all packages (including dies) and grades.
