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 | OUTA | output | Output of amplifier channel A. Class-AB output stage capable of sinking or sourcing current; short-circuit to GND is continuous for V+ ≤ 15 V (limited to ~40 mA). |+| 2 | -INA | input | Inverting input of amplifier channel A. High-impedance PNP input; input bias current typically 45 nA. Common-mode range includes ground (0 V to V+−1.5 V). |+| 3 | +INA | input | Non-inverting input of amplifier channel A. High-impedance PNP input; input common-mode range includes ground (0 V to V+−1.5 V). |+| 4 | GND/V- | power_in | Ground pin for single-supply operation, or the negative supply rail (V−) for split-supply operation. Split-supply range ±1.5 V to ±13 V for LM2904. |+| 5 | +INB | input | Non-inverting input of amplifier channel B. High-impedance PNP input; input common-mode range includes ground (0 V to V+−1.5 V). (Datasheet Pin Functions table labels this row 'Output, Channel B' but the pin diagram clearly shows pin 5 as +INB; treated as +INB.) |+| 6 | -INB | input | Inverting input of amplifier channel B. High-impedance PNP input; input bias current typically 45 nA. |+| 7 | OUTB | output | Output of amplifier channel B. Class-AB output stage capable of sinking or sourcing current; short-circuit to GND is continuous for V+ ≤ 15 V (limited to ~40 mA). |+| 8 | V+ | power_in | Positive supply pin. Single-supply range 3 V to 26 V for LM2904 (LM158/LM258/LM358 up to 32 V). Supply current typically 1 mA total for both amplifiers. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LM2904MXMX`+- `LM2904MXM`+- `LM2904MXDR`+- `LM2904MXD`+- `LM2904MXN`+- `LM2904MXP`+- `LM2904MXYPB`++## CAD (KiCad official)++- Symbol: `LM2904MX`+- 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/lm2904mx.pdf) (38 pp, sha256 `89107a55b932318a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
