Input common-mode range is 0V to V+ - 1.5V. Input bias current ~45nA (out of pin, PNP input stage). |+| 2 | V- | power_in | Negative supply / ground pin. Typically tied to GND in single-supply operation. Supply voltage (V+ - V-) up to 32V absolute maximum. |+| 3 | -IN | input | Inverting input of the op-amp. Input common-mode range is 0V to V+ - 1.5V. Input bias current ~45nA (out of pin, PNP input stage). |+| 4 | OUTPUT | output | Op-amp output. Output sourcing current typ 40mA, sinking current typ 20mA (V+=15V). Output short-circuit current to GND ~40mA. |+| 5 | V+ | power_in | Positive supply pin. Operating range +3V to +32V (single-supply); absolute max 32V (V+ - V-). Supply current typ 430uA at V+=5V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW Youtai Semiconductor Co   Ltd |+| Package | SOT-23-5L |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LM321MFMF`++## CAD (KiCad official)++- Symbol: `LM321MF`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW Youtai Semiconductor Co   Ltd datasheet](https://datasheet.lcsc.com/datasheet/pdf/3a81a721e0f799c575fc96bad873d280.pdf) (9 pp, sha256 `0a42ee731ed21976`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
