DUAL OPERATIONAL AMPLIFIERS

General Description

HWD4558

Features

The HWD4558 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 HWD4558 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/

Maximum power supply voltages: ± 18V

Compatible with NJM 4558
