DUAL LOW NOISE OPERATIONAL AMPLIFIERS
AZ4558A
General Description
Features
The AZ4558A consists of two low noise, high performance operational amplifiers. It is specially suitable
for applications in differential-in, differential-out as
well as in industrial measurement tools and applications where gain and phase matched channels are mandatory.
·
·
·
Operating voltage: ±2V ~ ±18V
Large DC voltage gain: 110 dB
Low input noise voltage: 1µVRMS
·
·
·
Wide gain bandwidth product: 7 MHz
Slew rate: 3V/µs
Package outline: DIP8, SOIC8
The IC features monolithic silicon chip, internal frequency 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.
