Input bias current typ. ±45 nA (max ±250 nA); common-mode input voltage range includes ground up to V+ − 1.5 V. |+| 2 | V- | power_in | Negative supply / ground pin. Tie to GND for single-supply operation, or to the negative rail for split-supply operation (±12 V max, 24 V total across V+ to V-). |+| 3 | -IN | input | Inverting op-amp input. Input offset voltage typ. ±2 mV (max ±5 mV); differential input voltage rating 24 V. |+| 4 | OUT | output | Op-amp output. Source current typ. 40 mA, sink current typ. 15 mA; short-circuit current to ground typ. 40 mA. Stable driving large capacitive loads. |+| 5 | V+ | power_in | Positive supply pin. Absolute maximum supply voltage 24 V (single) or ±12 V (split). Supply current typ. 0.5 mA at V+ = 5 V, 0.7 mA at V+ = 24 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Slkor SLKORMICRO Elec |+| Package | SOT-23-5 |+| Category | Op-amp/Cmp |+| Pins | 5 |++## CAD (KiCad official)++- Symbol: `LM321`+- 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:** [Slkor SLKORMICRO Elec datasheet](docs/lm321-datasheet.pdf) (5 pp, sha256 `6163ed0d8bef93ca`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
