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 | IN+ | input | Non-inverting analog input. Rail-to-rail common-mode range from (-VS)-0.1V to (+VS)+0.1V (VCM -0.1V to 5.6V at Vs=5.5V). Input bias current 10 nA typ. |+| 2 | VSS | power_in | Negative supply / ground. Tie to system GND for single-supply operation. Total supply (VDD-VSS) 2.1V to 5.5V (absolute max 7.5V). |+| 3 | IN- | input | Inverting analog input. Same common-mode and bias characteristics as IN+. Used with feedback network for closed-loop gain configuration. |+| 4 | OUT | output | Rail-to-rail amplifier output. Output current 20 mA min / 25 mA typ, slew rate 0.52 V/µs, GBW 1 MHz. |+| 5 | VDD | power_in | Positive supply rail. Operating range 2.1V to 5.5V (absolute max 7.5V). Decouple with 100 nF close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LMV321IDBVRIDBVR`++## CAD (KiCad official)++- Symbol: `LMV321IDBVR`+- 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/lmv321idbvr-datasheet.pdf) (15 pp, sha256 `92ba53cd7280c726`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
