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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `OPA991IDBVR`+- `OPA991IDBVT`+- `OPA991IDBVRSIDBVR`+- `OPA991IDBVRSIDBVT`+- `OPA991IDBVRIDCKR`+- `OPA991IDBVRIDCKT`++## CAD (KiCad official)++- Symbol: `OPA991IDBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/opa991idbvr-datasheet.pdf) (77 pp, sha256 `66cd6ff5fa13e39d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
