RS8552XM

Jiangsu RUNIC Tech · Precision OpAmps · MSOP-8

RS8552XM from Jiangsu RUNIC Tech, in a MSOP-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 CMOS output stage; short-circuit current 50 mA typ. VOH within ~2 mV of V+ with 100 kΩ load; VOL within ~1 mV of V- with 100 kΩ load.
2 -INA input Amplifier A inverting input. High-impedance CMOS input, rail-to-rail common-mode range (V--0.1 V to V++0.1 V). Diode-clamped to supply rails.
3 +INA input Amplifier A non-inverting input. High-impedance CMOS input, rail-to-rail common-mode range (V--0.1 V to V++0.1 V). Input bias current 50 pA typ.
4 V- power_in Negative supply rail (or ground for single-supply operation). Operating supply range +2.7 V to +5.5 V total (V+ minus V-); absolute maximum 7 V. Bypass with 0.1 µF ceramic close to the pin.
5 +INB input Amplifier B non-inverting input. High-impedance CMOS input, rail-to-rail common-mode range (V--0.1 V to V++0.1 V). Input bias current 50 pA typ.
6 -INB input Amplifier B inverting input. High-impedance CMOS input, rail-to-rail common-mode range (V--0.1 V to V++0.1 V). Diode-clamped to supply rails.
7 OUTB output Amplifier B output. Rail-to-rail CMOS output stage; short-circuit current 50 mA typ. VOH within ~2 mV of V+ with 100 kΩ load; VOL within ~1 mV of V- with 100 kΩ load.
8 V+ power_in Positive supply rail. Operating supply range +2.7 V to +5.5 V total (V+ minus V-); absolute maximum 7 V. Bypass with 0.1 µF ceramic close to the pin.
