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. Class-AB output stage capable of sourcing/sinking load current; short-circuit protected to ground for VS ≤ 15V. |+| 2 | IN1- | input | Inverting (negative) input of op-amp channel 1. Absolute maximum differential input voltage ±32V; input voltage range −0.3V to 40V (LM2904B). |+| 3 | IN1+ | input | Non-inverting (positive) input of op-amp channel 1. Common-mode input range extends to V− (ground), enabling true single-supply operation. |+| 4 | V- | power_in | Negative (lowest) supply rail, or ground for single-supply operation. Total supply VS = (V+) − (V−) range 3V to 36V (LM2904B), absolute max ±20V or 40V total. |+| 5 | IN2+ | input | Non-inverting (positive) input of op-amp channel 2. Common-mode input range includes V− (ground); typical input bias current 10nA, max 35nA. |+| 6 | IN2- | input | Inverting (negative) input of op-amp channel 2. Max input offset voltage 3mV at 25°C for the B version. |+| 7 | OUT2 | output | Output of op-amp channel 2. Class-AB output; short-circuit protected to ground for VS ≤ 15V with unlimited duration at TA = 25°C. |+| 8 | V+ | power_in | Positive (highest) supply rail. Operating supply 3V to 36V (LM2904B); integrated RF/EMI filtering on the supply for improved noise immunity. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904BIDRIDR`+- `LM2904BIDRID`+- `LM2904BIDRIDGKR`+- `LM2904BIDRIDGK`+- `LM2904BIDRIPWR`+- `LM2904BIDRIPW`+- `LM2904BIDRIDDFR`+- `LM2904BIDRIDDF`++## CAD (KiCad official)++- Symbol: `LM2904BIDR`+- 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/lm2904b.pdf) (68 pp, sha256 `ef646b009b0524a8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
