General Description
The AZ4558 consists of two high performance operational amplifiers. The IC features high gain, high input resistance, excellent channel separation, wide range of operating voltage and internal frequency compensation. It is specifically suitable for applications in differential-in, differential-out as well as in potential-metric amplifiers and where gain and phase matched channels are mandatory. The AZ4558 contains ± 18Vmaximum power supply voltage.
The AZ4558 is available in DIP-8 or SOIC-8 package.
