Input common-mode range includes ground; either input may go up to +32 V without damage. |+| 2 | V- | power_in | Negative supply / ground. In single-supply operation, tie to GND. Total supply voltage (V+ - V-) must not exceed 32 V. |+| 3 | -IN | input | Inverting input of the op-amp. Input common-mode range includes ground; either input may go up to +32 V without damage. |+| 4 | OUTPUT | output | Op-amp output. Sources up to ~40 mA and sinks up to ~20 mA. Short-circuit protected to GND (continuous when V+ ≤ 15 V, TA = 25°C). Stable with high capacitive loads. |+| 5 | V+ | power_in | Positive supply. Operating range +3 V to +30 V (absolute max 32 V). Supply current typically 430 µA at 5 V, no load. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## Ordering variants++- `LM321MFXMF`+- `LM321MFXMFX`++## CAD (KiCad official)++- Symbol: `LM321MFX`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lm321mfx.pdf) (16 pp, sha256 `9c21ba387dae8e4b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
