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 | OUTPUT 1 | output | Output of op-amp channel 1. Can swing from 0V to approximately Vcc-1.5V. Output short-circuit current typically 40 mA, source current up to 40 mA, sink current up to 13 mA at Vo=2V. |+| 2 | INPUT 1- | input | Inverting input of op-amp channel 1. Input bias current typically 45 nA (max 250 nA), input offset current typically 5 nA. Input common-mode range includes ground (0V) up to Vcc-1.5V. |+| 3 | INPUT 1+ | input | Non-inverting input of op-amp channel 1. Input bias current typically 45 nA. Input common-mode voltage range includes ground; upper limit is Vcc-1.5V. |+| 4 | GND | power_in | Ground / negative supply (Vee). In single-supply operation this is 0V; in split-supply operation this connects to the negative rail. Supply differential (Vcc - Vee) must be 3V to 26V (absolute max 30V). |+| 5 | INPUT 2+ | input | Non-inverting input of op-amp channel 2. Input bias current typically 45 nA. Input common-mode range includes ground up to Vcc-1.5V. |+| 6 | INPUT 2- | input | Inverting input of op-amp channel 2. Input bias current typically 45 nA (max 250 nA), input offset current typically 5 nA. |+| 7 | OUTPUT 2 | output | Output of op-amp channel 2. Can swing from 0V to approximately Vcc-1.5V. Output short-circuit current typically 40 mA. Channel separation from channel 1 is typically 120 dB (f = 1 kHz to 20 kHz). |+| 8 | Vcc | power_in | Positive supply voltage. Operating range Vcc = 3V to 26V single-supply, or ±1.5V to ±13V split-supply. Absolute maximum ±15V single or 30V differential. Typical supply current 0.5 mA at Vcc=5V, 0.8 mA at Vcc=25V (RL=∞). Bypass locally with a decoupling capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LRC |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `LR2904DD`++## CAD (KiCad official)++- Symbol: `LR2904D`+- 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:** [LRC datasheet](docs/lr2904d-datasheet.pdf) (7 pp, sha256 `6621c1f0759f20e9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
