OPA2347UA

UMW · Operational Amplifier · SOP-8

OPA2347UA from UMW, in a SOP-8. 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 OUTA output Amplifier A output. Rail-to-rail output stage; swings within 5mV of the supply rails with a 100kΩ load. Short-circuit current ±17mA typ.
2 -IN A input Amplifier A inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V. Input bias current ±0.5pA typ.
3 +IN A input Amplifier A non-inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V.
4 V- power_in Negative supply / ground. Total supply (V+)-(V-) between 2.3V (min operating) and 5.5V; absolute max 7.5V. Quiescent current 20µA typ per amplifier.
5 +IN B input Amplifier B non-inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V.
6 -IN B input Amplifier B inverting input. Rail-to-rail CMOS input; common-mode range extends from (V-)-0.2V to (V+)+0.2V.
7 OUTB output Amplifier B output. Rail-to-rail output stage; swings within 5mV of the rails with a 100kΩ load. Short-circuit current ±17mA typ.
8 V+ power_in Positive supply. Single-supply operation 2.3V to 5.5V (dual supply supported). Absolute max (V+)-(V-) = 7.5V. Decouple locally with a ceramic capacitor.

Provenance

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

  • Datasheet: UMW datasheet (14 pp, sha256 acb5619613b98db7, 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).
