Hangzhou Ruimeng Tech · Precision OpAmps · SOP-8

MS8552 from Hangzhou Ruimeng Tech, 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 OUTA output Amplifier A output. Rail-to-rail; swings within a few mV of the supply rails with a 10k or 100k load.
2 -INA input Amplifier A inverting input. High-impedance CMOS input, 20pA typ input bias current, common-mode range 0V to VS.
3 +INA input Amplifier A non-inverting input. High-impedance CMOS input, 20pA typ input bias current, common-mode range 0V to VS.
4 -VS power_in Negative supply / ground. Typically tied to GND for single-supply operation; total supply (VS to -VS) range is 2.5V to 5.5V.
5 +INB input Amplifier B non-inverting input. High-impedance CMOS input, 20pA typ input bias current, common-mode range 0V to VS.
6 -INB input Amplifier B inverting input. High-impedance CMOS input, 20pA typ input bias current, common-mode range 0V to VS.
7 OUTB output Amplifier B output. Rail-to-rail; swings within a few mV of the supply rails with a 10k or 100k load.
8 +VS power_in Positive supply. Single-supply range 2.5V to 5.5V referenced to -VS. Quiescent current 400µA/channel typ.
