LKA1200ST

LKWIC · Comparators · SOT-23-5

LKA1200ST from LKWIC, in a SOT-23-5. 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 VOUT output Comparator output terminal, which is push-pull and needs no external pull-up resistor according to the datasheet.
2 V- power_in Ground terminal (negative supply, V-) of the comparator, which sets the lower end of the supply range.
3 INP input Non-inverting comparator input, with a rail-to-rail common-mode input range extending to (V- - 200mV) to (V+ + 200mV).
4 INN input Inverting comparator input, with a rail-to-rail common-mode input range extending to (V- - 200mV) to (V+ + 200mV).
5 V+ power_in Positive supply terminal, operating from 2.7V to 5V single-supply as stated in the datasheet.

CAD (KiCad official)

  • Symbol: LKA1200ST
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lka1200st-etched.step / lka1200st-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lka1200st.step / lka1200st.glb are the bare package body.

Provenance

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

  • Datasheet: LKWIC datasheet (7 pp, sha256 b580d77afa5fa5c5, retrieved 2026-10-27, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
