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.
The AD629 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 AD629 has low offset, low offset drift, low gain error drift,
low common-mode rejection drift, and excellent CMRR over a
wide frequency range.
The AD629 is available in die and packaged form featuring
8-lead PDIP and 8-lead SOIC packages. For all packages
(including die) and grades, performance is guaranteed over
the industrial temperature range of 40°C to +85°C.
