Tie to GND for single-supply operation or to negative rail for dual-supply (±12V max). |+| 3 | -IN | input | Inverting op-amp input. Input offset voltage ±2 mV typ, input bias current ±45 nA typ. |+| 4 | OUTPUT | output | Op-amp output. Source current 20 mA typ, sink 10 mA typ at Vcc=15V. Short-circuit protected (continuous to ground for V≤15V). |+| 5 | V+ | power_in | Positive supply. Single-supply range up to 24V (or ±12V dual). Quiescent current 0.5 mA typ at 5V, 0.7 mA typ at 24V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | JSMSEMI LM321MFX |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LM321MFX-JSMMFX`++## CAD (KiCad official)++- Symbol: `LM321MFX-JSM`+- 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:** [JSMSEMI LM321MFX datasheet](docs/lm321mfx-jsm-datasheet.pdf) (5 pp, sha256 `4c2b85fecc25909f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
