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 low cost, 8-lead PDIP and 8-lead

SOIC packages. For all packages and grades, performance is

guaranteed over the industrial temperature range of −40°C to

+85°C.
