Dual Channel Operational Amplifiers
General Description
Features
EC4558
The EC4558 consists of two high performance opera-
Internal frequency compensation
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
Large DC voltage gain with 100 dB typical
High input resistance with 5M typical
Low input noise voltage with 10nV/ _HZ
Maximum power supply voltages: 18V
Compatible with NJM 4558
are mandatory. The EC4558 contains 18Vmaximum
power supply voltage.
Applications
The EC4558 is available in DIP-8 or SOIC-8 package.
