ACS724LLCTR-30AU-T-JSM

JSMSEMI · Current Sensors · SOP-8

ACS724LLCTR-30AU-T-JSM from JSMSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IP+ passive Current flows into the chip, positive direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms.
2 IP+ passive Current flows into the chip, positive direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms.
3 IP- passive Current flows out of the chip, negative direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms.
4 IP- passive Current flows out of the chip, negative direction; primary conductor with 0.85 mΩ typical resistance, isolated from signal pins to 3000 Vrms.
5 GND power_in Device ground terminal pin; reference for VCC supply and VOUT signal.
6 FILTER passive Bandwidth setting pin; connect an external capacitor to GND to reduce the internal low-pass filter cutoff frequency below the 250 kHz typical bandwidth.
7 VOUT output Analog output signal pin; ratiometric DC voltage proportional to sensed current, 66 mV/A sensitivity at VCC = 5 V for the 30 A variant.
8 VCC power_in Device power supply terminal pin; compatible with 3.3 V or 5 V supply, absolute maximum 6.5 V.

  • Symbol: ACS724LLCTR-30AU-T-JSM
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: acs724llctr-30au-t-jsm-etched.step / acs724llctr-30au-t-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); acs724llctr-30au-t-jsm.step / acs724llctr-30au-t-jsm.glb are the bare package body.

Provenance

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

  • Datasheet: JSMSEMI datasheet (16 pp, sha256 b0dfb2b3df2c3bec, retrieved 2026-09-29, 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).
