Jiangsu RUNIC Tech · Operational Amplifier · TSSOP-14

RS524XQ from Jiangsu RUNIC Tech, in a TSSOP-14. 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; typical short-circuit current 80mA, output swing within 7mV of the rails at RL=10k.
2 -IN A input Amplifier A inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V). Input bias current ~1pA typ.
3 +IN A input Amplifier A non-inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V). Input bias current ~1pA typ.
4 V+ power_in Positive supply rail. Single-supply 2.5V to 5.5V (or +/-1.25V to +/-2.75V split supply). Absolute max V+ to V- = 7.0V. Bypass with 0.1uF close to the pin.
5 +IN B input Amplifier B non-inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V).
6 -IN B input Amplifier B inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V).
7 OUT B output Amplifier B output. Rail-to-rail output; typical short-circuit current 80mA.
8 OUT C output Amplifier C output. Rail-to-rail output; typical short-circuit current 80mA.
9 -IN C input Amplifier C inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V).
10 +IN C input Amplifier C non-inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V).
11 V- power_in Negative supply rail (ground in single-supply operation). Absolute max V+ to V- = 7.0V. Bypass with 0.1uF close to the pin.
12 +IN D input Amplifier D non-inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V).
13 -IN D input Amplifier D inverting input. Rail-to-rail input, common-mode range -0.1V to Vs+0.1V (Vs=5.5V).
14 OUT D output Amplifier D output. Rail-to-rail output; typical short-circuit current 80mA.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs524xq.step 194 KB You want the bare part, or you mark your own boards.
rs524xq-etched.step 2.1 MB You want the part with RS524XQ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 515 faces against 237 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 c8e86d17f4ba6f0a, 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).
