Class-AB output stage able to sink and source current; short-circuit protected to V- (indefinite when Vs ≤ 15V at 25°C). |+| 2 | IN1- | input | Inverting (negative) input of op-amp channel 1. Common-mode range extends from V- to (V+ - 2V). Differential input voltage rating ±32V. |+| 3 | IN1+ | input | Non-inverting (positive) input of op-amp channel 1. Common-mode range extends from V- to (V+ - 2V), allowing direct sensing near ground in single-supply operation. |+| 4 | V- | power_in | Negative (lowest) supply rail. Tie to ground for single-supply operation. Supply voltage Vs = (V+) - (V-) rated 3V to 32V for LM258A. |+| 5 | IN2+ | input | Non-inverting (positive) input of op-amp channel 2. Common-mode range extends from V- to (V+ - 2V). |+| 6 | IN2- | input | Inverting (negative) input of op-amp channel 2. Differential input voltage rating ±32V. |+| 7 | OUT2 | output | Output of op-amp channel 2. Class-AB output; short-circuit protected to V-. |+| 8 | V+ | power_in | Positive (highest) supply rail. Supply voltage Vs = (V+) - (V-) rated 3V to 32V for LM258A (absolute maximum ±16V or 32V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM258ADRDR`+- `LM258ADRD`+- `LM258ADRDGK`+- `LM258ADRPW`+- `LM258ADRP`+- `LM258ADRPS`++## CAD (KiCad official)++- Symbol: `LM258ADR`+- 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/lm258a.pdf) (68 pp, sha256 `ef646b009b0524a8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
