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 | Op-amp output. Rail-to-rail output stage swings to within ~1 mV of V+ and V- with a 100-kΩ load. |+| 2 | V- | power_in | Negative (lowest) power supply rail. Typically ground in single-supply operation; total supply range V+ to V- is 2.5 V to 5.5 V. |+| 3 | +IN | input | Non-inverting (positive) analog input. Common-mode range extends 500 mV below V- and 500 mV above V+. |+| 4 | -IN | input | Inverting (negative) analog input. Common-mode range extends 500 mV below V- and 500 mV above V+. |+| 5 | V+ | power_in | Positive (highest) power supply rail. Single-supply operation from 2.5 V up to 5.5 V (V+ to V-). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `OPA340NANA`++## CAD (KiCad official)++- Symbol: `OPA340NA`+- 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:** [UMW datasheet](docs/opa340na-datasheet.pdf) (18 pp, sha256 `e75e687924f6aa75`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
