RS622XM

Jiangsu RUNIC Tech · Operational Amplifier · MSOP-8

RS622XM 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; typical output short-circuit current 50 mA, output swing to within ~7 mV of the rails at RL = 10 kΩ.
2 -INA input Amplifier A inverting input. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V (spec'd to +5.6 V at Vs = 5.5 V). Input bias current ~1 pA typical.
3 +INA input Amplifier A non-inverting input. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical.
4 V- power_in Negative supply / ground. For single-supply operation tie to GND; supply span V+ to V- must be 2.5 V to 5.5 V (7.0 V absolute max).
5 +INB input Amplifier B non-inverting input. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical.
6 -INB input Amplifier B inverting input. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current ~1 pA typical.
7 OUTB output Amplifier B output. Rail-to-rail CMOS output; typical output short-circuit current 50 mA, output swing to within ~7 mV of the rails at RL = 10 kΩ.
8 V+ power_in Positive supply. 2.5 V to 5.5 V referenced to V- (7.0 V absolute max V+ to V-). Bypass with a 0.1 uF (and optional 10 uF) capacitor close to the pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
rs622xm.step 123 KB You want the bare part, or you mark your own boards.
rs622xm-etched.step 1.8 MB You want the part with RS622XM already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 440 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Jiangsu RUNIC Tech datasheet (18 pp, sha256 5cc06cc083590cda, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
