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. Class-AB output stage swings from V- rail to within ~1.5 V of V+; short-circuit current ~40 mA typical. |+| 2 | IN1- | input | Inverting (negative) input of op amp 1. High input impedance (10 MΩ differential typical); input bias current ~-10 nA typical, -35 nA max (B/BA versions). |+| 3 | IN1+ | input | Non-inverting (positive) input of op amp 1. Common-mode input range extends from V- (ground in single-supply operation) up to V+ - 1.5 V. |+| 4 | V- | power_in | Negative (lowest) supply, or ground for single-supply operation. Total supply (V+ - V-) may range 3 V to 32 V (LM258/LM258A); absolute max 32 V. |+| 5 | IN2+ | input | Non-inverting (positive) input of op amp 2. Common-mode input range extends from V- (ground in single-supply operation) up to V+ - 1.5 V. |+| 6 | IN2- | input | Inverting (negative) input of op amp 2. High input impedance (10 MΩ differential typical); input bias current ~-10 nA typical (B/BA versions). |+| 7 | OUT2 | output | Output of op amp 2. Class-AB output stage swings from V- rail to within ~1.5 V of V+; short-circuit current ~40 mA typical. |+| 8 | V+ | power_in | Positive (highest) supply. Operating range 3 V to 32 V (LM258/LM258A) referenced to V-; quiescent current 300 µA per amplifier typical. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM258DRD`+- `LM258DRDR`+- `LM258DRDGK`+- `LM258DRDGKR`+- `LM258DRP`+- `LM258DRPS`+- `LM258DRPW`+- `LM258DRPWR`++## CAD (KiCad official)++- Symbol: `LM258DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (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/lm258.pdf) (68 pp, sha256 `ef646b009b0524a8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
