General Description
Features
Data Sheet
AZ4558
The AZ4558 consists of two high performance opera-
tional amplifiers. The IC features high gain, high input
resistance, excellent channel separation, wide range of
operating voltage and internal frequency compensa-
tion. It is specifically suitable for applications in differ-
ential-in, differential-out as well as in potential-metric
amplifiers and where gain and phase matched channels
are mandatory. The AZ4558 contains ± 18Vmaximum
power supply voltage.
· Internal frequency compensation
· Large DC voltage gain with 100 dB typical
· High input resistance with 5MΩ typical
· Low input noise voltage with 10nV/ HZ
· Maximum power supply voltages: ± 18V
· Compatible with NJM 4558
Applications
The AZ4558 is available in DIP-8 or SOIC-8 package. · Audio AC-3 decoded system
· Audio amplifier
