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 capable with common-mode range extending 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). Input bias current 1pA typical. |+| 2 | VSS | power_in | Negative supply / ground. Tie to ground for single-supply operation (2.1V to 5.5V referenced to VDD) or to the negative rail for dual-supply operation (±1.05V to ±2.75V). |+| 3 | IN- | input | Inverting analog input. Rail-to-rail capable with common-mode range extending 100mV beyond the supply rails. Input offset voltage 3.5mV max at 25°C. |+| 4 | OUT | output | Amplifier output. Rail-to-rail swing (typically within 5mV of the rails at RL>100kΩ, 30mV at 10kΩ). Sources 84mA / sinks 75mA typical short-circuit current. |+| 5 | VDD | power_in | Positive supply, 2.1V to 5.5V (absolute max 7.5V VDD-VSS). Bypass with a 0.1μF ceramic capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LMV321-TRTR`+- `LMV321-TRSR`+- `LMV321-TRSR`++## CAD (KiCad official)++- Symbol: `LMV321-TR`+- 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:** [Gainsil datasheet](docs/lmv321-tr-datasheet.pdf) (12 pp, sha256 `3e4d4c64aa5067d2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
