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
