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 input; common-mode range extends from (V-) - 0.1 V to (V+) + 0.1 V. Input bias current ~1 pA at 25 °C. ESD-protected with clamp diodes to each rail; keep input current below ±10 mA if the pin is driven beyond the supplies. |+| 2 | -Vs | power_in | Negative supply rail (typically GND in single-supply operation). Total supply voltage (V+) - (V-) must not exceed 6 V absolute maximum; recommended 2.5 V to 5.5 V total. |+| 3 | -In | input | Inverting analog input. Rail-to-rail input; common-mode range extends 100 mV beyond each supply rail. Input bias current ~1 pA at 25 °C; input capacitance 8 pF differential / 7 pF common-mode. |+| 4 | Out | output | Rail-to-rail analog output. Swings to within 15 mV of each supply rail with a 10 kΩ load. Short-circuit current typically 100 mA (indefinite short-circuit duration allowed, subject to junction-temperature limits). |+| 5 | +Vs | power_in | Positive supply rail. Operating range 2.5 V to 5.5 V referenced to -Vs; absolute maximum (+Vs) - (-Vs) = 6 V. Quiescent current 80 µA typical (130 µA max) per amplifier. Bypass with a local decoupling capacitor to -Vs. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 3PEAK |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LMV321B-TRTR`+- `LMV321B-TRCR`++## CAD (KiCad official)++- Symbol: `LMV321B-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:** [3PEAK datasheet](docs/lmv321b-tr-datasheet.pdf) (16 pp, sha256 `77ea0faba82619fb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
