AS321KTR

TECH PUBLIC · Operational Amplifier · SOT-23-5

AS321KTR from TECH PUBLIC, 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 +IN input Non-inverting analog input to the op-amp. Common-mode input voltage range is 0 to Vcc-1.5V; input bias current is typically -20nA.
2 -Vs power_in Negative supply / ground reference. Connect to GND for single-supply operation, or to the negative rail (down to -20V) for split-supply operation.
3 -IN input Inverting analog input to the op-amp. Common-mode input voltage range is 0 to Vcc-1.5V; input bias current is typically -20nA.
4 OUT output Op-amp output. Rail-to-negative output swing from 0V up to Vcc-1.5V; short-circuit protected with typical short-circuit output current of 40mA.
5 +Vs power_in Positive supply. Single-supply range 3V to 36V (absolute max 40V); split-supply up to ±20V. Typical quiescent supply current is 0.7mA (max 1.2mA at Vo=2.5V, no load).

  • AS321KTR

CAD (KiCad official)

  • Symbol: AS321KTR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: as321ktr-etched.step / as321ktr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); as321ktr.step / as321ktr.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (None pp, sha256 addf6856e9512635, 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).
