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 of the op-amp. Rail-to-rail input common-mode range from (-VS)-0.1V to (+VS)+0.1V at VS=5.5V; typical input bias current 10 nA. |+| 2 | VSS | power_in | Negative supply / ground pin. Connect to system ground for single-supply operation or to the negative rail for dual-supply operation. Absolute maximum supply voltage (VDD-VSS) is 7.5 V; recommended operating range 2.1 V to 5.5 V. |+| 3 | IN- | input | Inverting analog input of the op-amp. Rail-to-rail input common-mode range; typical input offset current 10 nA and input bias current 10 nA. |+| 4 | OUT | output | Rail-to-rail op-amp output. Typical output current 25 mA, short-circuit protected; slew rate 0.52 V/µs. |+| 5 | VDD | power_in | Positive supply pin. Recommended operating range 2.1 V to 5.5 V (7.5 V absolute maximum). Bypass to VSS with a local 0.1 µF ceramic capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SC-70-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LMV321IDCKRIDCKR`+- `LMV321IDCKRDCK`+- `LMV321IDCKRIDBVR`+- `LMV321IDCKRDBV`+- `LMV321IDCKRLMV358`+- `LMV321IDCKRLMV358`+- `LMV321IDCKRLMV324`+- `LMV321IDCKRLMV324`++## CAD (KiCad official)++- Symbol: `LMV321IDCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/lmv321idckr-datasheet.pdf) (15 pp, sha256 `92ba53cd7280c726`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
