GS4558-SR

Gainsil · Operational Amplifier · SOP-8

GS4558-SR from Gainsil, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTPUT 1 output Output of amplifier 1. Typical output resistance 45Ω; short-circuit sink/source currents ~60mA/35mA.
2 INPUT 1- input Inverting input of amplifier 1. High input impedance (~0.5MΩ); input bias current typically 70nA.
3 INPUT 1+ input Non-inverting input of amplifier 1. Common-mode input voltage range typically ±12V at ±15V supply.
4 VEE power_in Negative supply rail. Recommended −2V to −18V; absolute maximum −20V.
5 INPUT 2+ input Non-inverting input of amplifier 2. Common-mode input voltage range typically ±12V at ±15V supply.
6 INPUT 2- input Inverting input of amplifier 2. High input impedance (~0.5MΩ); input bias current typically 70nA.
7 OUTPUT 2 output Output of amplifier 2. Typical output resistance 45Ω; short-circuit sink/source currents ~60mA/35mA.
8 VCC power_in Positive supply rail. Recommended +2V to +18V; absolute maximum +20V. Total supply current typically 2.5mA (all amplifiers, no load).
