MS358

Hangzhou Ruimeng Tech · Operational Amplifier · SOP-8

MS358 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 OUT1 output Output of op-amp A. Class-A output at small signals, class-B at large signals, sourcing up to ~30 mA and sinking up to ~8 mA at V+=15 V. Short-circuit-to-ground current is ~30-85 mA at V+=15 V; sustained shorts to V+ will destroy the die.
2 IN1- input Inverting input of op-amp A. High-impedance PNP input with ~30 nA typical input bias current and ~3 mV typical input offset voltage. Absolute-max input voltage -0.3 V to 40 V; do not drive below V- - 0.3 V or the internal PNP base-collector diode will conduct.
3 IN1+ input Non-inverting input of op-amp A. Common-mode input range extends from ground (V-) up to V+ - 1.5 V, allowing single-supply operation. Same absolute-max limits as IN1-.
4 GND power_in Negative supply / ground (V-). In single-supply operation tie to 0 V; in split-supply operation tie to the negative rail. Total supply voltage (V+ - V-) must not exceed 40 V.
5 IN2+ input Non-inverting input of op-amp B. Same electrical characteristics as IN1+: rail-to-ground common-mode range up to V+ - 1.5 V and 30 nA typical bias current.
6 IN2- input Inverting input of op-amp B. Same electrical characteristics as IN1-: ~30 nA bias current, ~3 mV offset, and same absolute-max voltage limits.
7 OUT2 output Output of op-amp B. Same drive capability as OUT1: ~30 mA source / ~8 mA sink at V+=15 V, VO=2 V, with VOL ~5 mV at RL=10 k to ground.
8 VCC power_in Positive supply (V+). Operating range 2.5 V to 36 V single-supply (up to 40 V absolute max V+ - V-). Bypass with 0.1 uF ceramic to GND close to the pin to reduce noise coupling.
