Dual Channel Operational Amplifiers

EC4558

Dual Channel Operational Amplifiers
General Description
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. The EC4558 is available in DIP-8 or SOIC-8 package.

Absolute Maximum Ratings (Note 1)
Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. 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.
