General Description
Features
Data Sheet
HWD4558
The HWD4558 consists of two high performance opera- · Internal frequency compensation
tional amplifiers. The IC features high gain, high input · Large DC voltage gain with 100 dB typical
resistance, excellent channel separation, wide range of
operating voltage and internal frequency compensa-
tion. It is specifically suitable for applications in differ-
·
·
High input resistance with 5MΩ typical
Low input noise voltage with 10nV/ HZ
ential-in, differential-out as well as in potential-metric · Maximum power supply voltages: ± 18V
amplifiers and where gain and phase matched channels · Compatible with NJM 4558
are mandatory. The HWD4558 contains ± 18Vmaximum
power supply voltage.
Applications
The HWD558 is available in DIP-8 or SOIC-8 package. · Audio AC-3 decoded system
