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 will operate
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,
as well as low common-mode rejection drift, and excellent CMRR
over a wide frequency range.
The AD629 is available in low-cost, plastic 8-lead DIP and
SOIC packages. For all packages and grades, performance is
guaranteed over the entire industrial temperature range from
–40
°
C to +85
°
C.
