Class-AB push-pull stage, capable of sinking/sourcing typical short-circuit current; output swings from V- (rail-to-rail low) to within about 1.5 V of V+. |+| 2 | IN1- | input | Inverting (negative) input of op-amp channel 1. High-impedance PNP input; common-mode input range extends down to V-. |+| 3 | IN1+ | input | Non-inverting (positive) input of op-amp channel 1. High-impedance PNP input; common-mode input range extends down to V-. |+| 4 | V- | power_in | Negative (most negative) supply rail, or GND for single-supply operation. Total supply voltage V+ to V- must be 3 V to 36 V (LM2904B/BA-Q1). |+| 5 | IN2+ | input | Non-inverting (positive) input of op-amp channel 2. High-impedance PNP input; common-mode input range extends down to V-. |+| 6 | IN2- | input | Inverting (negative) input of op-amp channel 2. High-impedance PNP input; common-mode input range extends down to V-. |+| 7 | OUT2 | output | Output of op-amp channel 2. Class-AB push-pull stage; output swings from V- (rail-to-rail low) to within about 1.5 V of V+. |+| 8 | V+ | power_in | Positive (most positive) supply rail. Absolute range 3 V to 36 V referenced to V- for LM2904B-Q1 / LM2904BA-Q1. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904BQDRQ1D`+- `LM2904BQDRQ1`+- `LM2904BQDRQ1DGK`+- `LM2904BQDRQ1DGKR`+- `LM2904BQDRQ1PW`+- `LM2904BQDRQ1PWR`++## CAD (KiCad official)++- Symbol: `LM2904BQDRQ1`+- 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](docs/lm2904bqdrq1-datasheet.pdf) (42 pp, sha256 `78558509b401573f`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
