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 | Out1 | output | Output of op-amp 1. Can swing from 0 V to (VCC+ - 1.5 V); short-circuit protected with output current limited to approximately 40 mA. |+| 2 | In1- | input | Inverting input of op-amp 1. Absolute input voltage range -0.3 V to 32 V; differential input range ±32 V. |+| 3 | In1+ | input | Non-inverting input of op-amp 1. Common-mode range includes the negative supply (Vcc-/GND). |+| 4 | Vcc- | power_in | Negative supply rail (or ground in single-supply operation). Total supply voltage (Vcc+ to Vcc-) up to ±16 V or 32 V single-supply. |+| 5 | In2+ | input | Non-inverting input of op-amp 2. Common-mode range includes the negative supply (Vcc-/GND). |+| 6 | In2- | input | Inverting input of op-amp 2. Absolute input voltage range -0.3 V to 32 V; differential input range ±32 V. |+| 7 | Out2 | output | Output of op-amp 2. Can swing from 0 V to (VCC+ - 1.5 V); short-circuit protected with output current limited to approximately 40 mA. |+| 8 | Vcc+ | power_in | Positive supply rail. Operates from 3 V to 32 V single-supply or ±1.5 V to ±16 V split-supply. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SO-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM258DTDT`+- `LM258DTADT`+- `LM258DTAYDT`+- `LM258DTYDT`+- `LM258DTPT`+- `LM258DTAPT`+- `LM258DTST`+- `LM258DTAST`+- `LM258DTQT`++## CAD (KiCad official)++- Symbol: `LM258DT`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/lm258dt.pdf) (25 pp, sha256 `40a2550bed90848d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
