OPA991IDBVR

Texas Instruments · Operational Amplifier · SOT-23-5

OPA991IDBVR from Texas Instruments, 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 capable of sourcing/sinking ±75 mA and driving capacitive loads up to 1 nF.
2 V- power_in Negative (lowest) supply rail. Single-supply GND or negative rail of a bipolar supply. Total supply range 2.7 V to 40 V (±1.35 V to ±20 V) across V+ and V-.
3 IN+ input Non-inverting input. Rail-to-rail input common-mode range; low input bias current (typ ±10 pA).
4 IN- input Inverting input. Rail-to-rail input common-mode range; low input bias current (typ ±10 pA).
5 V+ power_in Positive (highest) supply rail. Total supply range 2.7 V to 40 V (±1.35 V to ±20 V) across V+ and V-. Quiescent current ~560 µA per amplifier.

  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: opa991idbvr-etched.step / opa991idbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa991idbvr.step / opa991idbvr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (77 pp, sha256 66cd6ff5fa13e39d, retrieved 2026-08-17, 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: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
