Dual Channel Operational Amplifiers General Description EC4558 Features The EC4558 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 EC4558 contains 18Vmaximum power supply voltage. Internal frequency compensation 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 Applications The EC4558 is available in DIP-8 or SOIC-8 package.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability.
