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 · High input resistance with 5MΩ typical

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
