RS822XK

Jiangsu RUNIC Tech · Operational Amplifier · SOP-8

RS822XK from Jiangsu RUNIC 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 OUT A output Amplifier A output. Rail-to-rail output stage; typical output swing within 20mV of rails at RL=2kΩ, 7mV at RL=10kΩ. Short-circuit current ~110mA.
2 -IN A input Inverting input of amplifier A. High-impedance CMOS input, IB ~1pA typical. Input common-mode range -0.1V to +5.6V at Vs=5.5V; internally diode-clamped to supply rails (limit external drive to ±10mA beyond rails).
3 +IN A input Non-inverting input of amplifier A. High-impedance CMOS input, IB ~1pA typical, rail-to-rail input common-mode range.
4 V- power_in Negative supply rail (or ground in single-supply operation). Total supply voltage V+ to V- range 2.5V to 5.5V (absolute max 7.0V). Place 0.1uF bypass capacitor close to the pin.
5 +IN B input Non-inverting input of amplifier B. High-impedance CMOS input, IB ~1pA typical, rail-to-rail input common-mode range.
6 -IN B input Inverting input of amplifier B. High-impedance CMOS input, IB ~1pA typical; internally diode-clamped to supply rails.
7 OUT B output Amplifier B output. Rail-to-rail output stage; typical output swing within 20mV of rails at RL=2kΩ, 7mV at RL=10kΩ. Short-circuit current ~110mA.
8 V+ power_in Positive supply rail. Total supply voltage V+ to V- range 2.5V to 5.5V (absolute max 7.0V). Iq ~1.9mA per amplifier. Place 0.1uF bypass capacitor close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs822xk.step 122 KB You want the bare part, or you mark your own boards.
rs822xk-etched.step 1.9 MB You want the part with RS822XK already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 453 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 (14 pp, sha256 2cea6757d2650c10, 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).
