RS722PXK

Jiangsu RUNIC Tech · Operational Amplifier · SOP-8

RS722PXK 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 OUTA output Output of amplifier channel A. Rail-to-rail output; can source/sink up to ~140 mA typical, short-circuit protected.
2 -INA input Inverting input, channel A. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical.
3 +INA input Noninverting input, channel A. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical.
4 V- power_in Negative (lowest) power supply. Connect to ground for single-supply operation; supports single-supply 2.5V to 5.5V or dual-supply ±1.25V to ±2.75V.
5 +INB input Noninverting input, channel B. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical.
6 -INB input Inverting input, channel B. Rail-to-rail CMOS input; common-mode range -0.2V to +5.7V with Vs=5.5V. Input bias current ~1 pA typical.
7 OUTB output Output of amplifier channel B. Rail-to-rail output; can source/sink up to ~140 mA typical, short-circuit protected.
8 V+ power_in Positive (highest) power supply. Single-supply 2.5V to 5.5V, absolute max Vs=(V+)-(V-)=7V. Quiescent current ~1.1 mA per amplifier.

Two STEP files. Same geometry, different body top:

File Size Use it when
rs722pxk.step 122 KB You want the bare part, or you mark your own boards.
rs722pxk-etched.step 1.7 MB You want the part with RS722PXK already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 437 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 (23 pp, sha256 396034a195cebc33, 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).
