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. Input common-mode range extends from ground (V-) to V+ - 1.5V. Input bias current is typically 45nA (out of the pin due to PNP input stage). |+| 2 | V- | power_in | Negative supply / ground. In single-supply operation this pin is tied to ground; in dual-supply operation it connects to the negative rail. Total supply (V+ - V-) is rated 3V to 32V (30V operating). |+| 3 | -IN | input | Inverting input of the op amp. Input common-mode range extends from ground (V-) to V+ - 1.5V. Input bias current is typically 45nA (out of the pin due to PNP input stage). |+| 4 | OUTPUT | output | Op amp output. Typical output swing is up to V+ - 2V with 2kΩ load. Output current sourcing up to 40mA typical; short-circuit current to ground ~40mA. Stable driving large capacitive loads. |+| 5 | V+ | power_in | Positive power supply. Operating range +3V to +30V; absolute max 32V. Typical supply current is 430µA at V+ = 5V (1.15mA max) and 660µA at V+ = 30V (2.85mA max). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LM321G-AE5-R`+- `LM321G-AE5-RLM321L-AE5-R`++## CAD (KiCad official)++- Symbol: `LM321G-AE5-R`+- 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:** [UTC Unisonic Tech datasheet](docs/lm321g-ae5-r-datasheet.pdf) (7 pp, sha256 `516da351bd5b42b3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
