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 channel 1. Can swing from 0 V up to (Vcc+ - 1.5 V); short-circuit protected with typical short-circuit output current ~40 mA when Vcc > 15 V. |+| 2 | In1- | input | Inverting input of op-amp channel 1. Input bias current typically 20 nA; input voltage range -0.3 V to 32 V; differential input voltage rating ±32 V. |+| 3 | In1+ | input | Non-inverting input of op-amp channel 1. Common-mode voltage range includes the negative rail (Vcc-/GND) up to Vcc+ - 1.5 V. |+| 4 | Vcc- | power_in | Negative supply / ground pin. In single-supply operation tie to GND; in dual-supply operation connect to the negative rail. Total supply span (Vcc+ to Vcc-) up to 32 V (or ±16 V). |+| 5 | In2+ | input | Non-inverting input of op-amp channel 2. Common-mode voltage range includes the negative rail (Vcc-/GND) up to Vcc+ - 1.5 V. |+| 6 | In2- | input | Inverting input of op-amp channel 2. Input bias current typically 20 nA; input offset voltage typically 2 mV. |+| 7 | Out2 | output | Output of op-amp channel 2. Rail-to-rail-lower output swing (0 V to Vcc+ - 1.5 V); short-circuit protected. |+| 8 | Vcc+ | power_in | Positive supply pin. Operates from 3 V up to 32 V single-supply (or ±16 V dual-supply). Very low quiescent current per channel, essentially independent of supply voltage. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SO-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM258ADT`+- `LM258ADTLM258AYDT`+- `LM258ADTLM258DT`+- `LM258ADTLM358ADT`+- `LM258ADTLM358YDT`+- `LM258ADTLM358DT`+- `LM258ADTLM258AST`+- `LM258ADTLM358ST`+- `LM258ADTLM358AST`+- `LM258ADTLM158QT`+- `LM258ADTLM258QT`+- `LM258ADTLM358QT`+- `LM258ADTLM258APT`+- `LM258ADTLM358PT`+- `LM258ADTLM358APT`++## CAD (KiCad official)++- Symbol: `LM258ADT`+- 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/lm258adt.pdf) (25 pp, sha256 `40a2550bed90848d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
