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 input of the op-amp. Common-mode input range: -0.1V to (VDD-1.5V). Input bias current typically 45nA. |+| 2 | VSS | power_in | Negative supply / ground. Connect to GND for single-supply operation (+3V to +28V on VDD) or to the negative rail (down to -14V) for dual-supply operation. |+| 3 | IN- | input | Inverting input of the op-amp. Common-mode input range: -0.1V to (VDD-1.5V). Input bias current typically 45nA. |+| 4 | OUT | output | Op-amp output. Output current up to ±40mA typical (60mA max). VOH ≥ 11V and VOL ≤ 20mV with RL = 2kΩ at VS = +14V. |+| 5 | VDD | power_in | Positive supply pin. Operating range 3V to 28V single-supply (or up to +14V in dual-supply). Bypass to VSS with a 0.1µF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Gainsil |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LM321-TR`+- `LM321-TRLM358-SR`+- `LM321-TRLM358-MR`+- `LM321-TRLM324-SR`++## CAD (KiCad official)++- Symbol: `LM321-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/lm321-tr-datasheet.pdf) (12 pp, sha256 `e614f8c2e1c0a60b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
