DUAL LOW NOISE OPERATIONAL AMPLIFIERS
AZ4558A
General Description
Features
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.
·
Operating voltage: ±2V ~ ±18V
·
·
Large DC voltage gain: 110 dB
Low input noise voltage: 1µV
RMS
·
·
·
Wide gain bandwidth product: 7 MHz
Slew rate: 3V/µs
Package outline: DIP8, SOIC8
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.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum
Ratings" for extended periods may affect device reliability.
