Class-AB output stage capable of sinking/sourcing loads to V- (ground in single-supply operation). Short-circuit to V- allowed indefinitely for VS ≤ 15 V at TA = 25 °C. |+| 2 | IN1- | input | Inverting (negative) input of op-amp channel 1. High-impedance BJT input; differential input voltage rated ±32 V (VID). Input voltage range -0.3 V to 32 V. |+| 3 | IN1+ | input | Non-inverting (positive) input of op-amp channel 1. Common-mode input range includes V- (ground), enabling ground sensing in single-supply operation. |+| 4 | V- | power_in | Negative (lowest) supply rail, or ground for single-supply operation. Supply span (V+) - (V-) rated up to 32 V for the AV/A variants (26 V absolute max on plain LM2904). |+| 5 | IN2+ | input | Non-inverting (positive) input of op-amp channel 2. Common-mode input range includes V- (ground). |+| 6 | IN2- | input | Inverting (negative) input of op-amp channel 2. High-impedance BJT input; differential input voltage rated ±32 V. |+| 7 | OUT2 | output | Output of op-amp channel 2. Class-AB output stage capable of sinking/sourcing loads to V- (ground in single-supply operation). |+| 8 | V+ | power_in | Positive (highest) supply rail. Recommended supply range 3 V to 32 V (LM2904AV); absolute-maximum total supply is 32 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904AVQDRD`+- `LM2904AVQDRDR`+- `LM2904AVQDRPW`+- `LM2904AVQDRPWR`++## CAD (KiCad official)++- Symbol: `LM2904AVQDR`+- 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/lm2904avq.pdf) (56 pp, sha256 `c15277a33a04f41f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
