CSA220LASOT235

analogysemi · Current-Sensing Amplifiers · SOT-23-5

CSA220LASOT235 from analogysemi, in a SOT-23-5. 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 GND power_in Device ground reference.
2 OUT output Analog output. Output voltage equals (RS+ − RS−) × Gain (10V/V for CSA220-10). VOH ≈ VDD − 15mV (500µA source), VOL ≈ 15mV (500µA sink).
3 VDD power_in Supply voltage input, 2.7V to 5.5V (3.3V nominal). Bypass with at least 100nF ceramic capacitor to GND.
4 RS- input Load-side connection of the external current-sense resistor (inverting input). Common-mode range 0V to 76V relative to GND; RS+ to RS− differential range ±80V (1s max).
5 RS+ input Power-side connection of the external current-sense resistor (non-inverting input). Common-mode range 0V to 76V relative to GND.

CAD (KiCad official)

  • Symbol: CSA220LASOT235
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: csa220lasot235-etched.step / csa220lasot235-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); csa220lasot235.step / csa220lasot235.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
csa220lasot235.step 85 KB You want the bare part, or you mark your own boards.
csa220lasot235-etched.step 2.7 MB You want the part with CSA220LASOT235 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 643 faces against 102 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: analogysemi datasheet (13 pp, sha256 963c8a26e263d7bd, 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).
