DIO20721ST5

DIOO · Operational Amplifier · SOT-23-5

DIO20721ST5 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 stage; typical output current 85mA at V+=5V (20-27mA at V+=2.5V) with closed-loop output impedance ~2.8Ω at 1MHz.
2 V- power_in Negative supply / ground reference. Tie to GND for single-supply operation. Supply range (V+ - V-) is 2.5V to 5.5V (absolute max 7V).
3 +IN input Non-inverting input. Rail-to-rail common-mode range from (V-)-0.1V to (V+)+0.1V. Input bias current ~1pA.
4 -IN input Inverting input. Rail-to-rail common-mode range from (V-)-0.1V to (V+)+0.1V. Input offset voltage 0.5mV typical (±5mV max over -40 to 125°C).
5 V+ power_in Positive supply. 2.5V to 5.5V recommended (absolute max 7V). Decouple close to the pin. PSRR is 110dB typical.

  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: dio20721st5-etched.step / dio20721st5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dio20721st5.step / dio20721st5.glb are the bare package body.

Provenance

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

  • Datasheet: DIOO datasheet (None pp, sha256 036a412f5f53e626, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
