DIO20321ST5

DIOO · Operational Amplifier · SOT-23-5

DIO20321ST5 from DIOO, 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 OUT output Amplifier output. Rail-to-rail output swing; typical output current 48mA at V+=5V; closed-loop output impedance ~2.6Ω at 100kHz.
2 -Vs power_in Negative supply rail (typically GND in single-supply operation). Supply voltage range 2.5V to 5.5V referenced between +Vs and -Vs.
3 +IN input Non-inverting analog input. Common-mode range -0.1V to (V+)+0.1V (rail-to-rail); input bias current typically 1pA.
4 -IN input Inverting analog input. Common-mode range -0.1V to (V+)+0.1V; input offset voltage typically 0.7mV (±3.5mV max).
5 +Vs power_in Positive supply rail. Operating range 2.5V to 5.5V; absolute maximum 7.5V. Recommended bypass with 10µF and 0.1µF capacitors to -Vs.

  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: dio20321st5-etched.step / dio20321st5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dio20321st5.step / dio20321st5.glb are the bare package body.

Provenance

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

  • Datasheet: DIOO datasheet (8 pp, sha256 7c7f8bb428c64ba3, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
