AZ4558A
DUAL LOW NOISE OPERATIONAL AMPLIFIERS
General Description
The AZ4558A consists of two low noise, high perfor-
mance operational amplifiers. It is specially suitable
for applications in differential-in, differential-out as
well as in industrial measurement tools and applica-
tions where gain and phase matched channels are man-
datory.
The IC features monolithic silicon chip, internal fre-
quency compensation, low noise, low distortion, wide
operating voltage range, high gain and high bandwidth.
The AZ4558A can operate under dual power supply
voltage up to
±18V
or single power supply up to 36V.
