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 | OUT A | output | Output of amplifier channel A. Rail-to-rail output; swings within a few mV of V+/V- with a 100 kΩ load and ~10 mV of the rails with 10 kΩ. |+| 2 | -IN A | input | Inverting input of amplifier channel A. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V; input bias current ~50 pA typical. |+| 3 | +IN A | input | Non-inverting input of amplifier channel A. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V; input bias current ~50 pA typical. |+| 4 | V+ | power_in | Positive supply rail. Single-supply +2.7 V to +5.5 V, or ±1.35 V to ±2.75 V dual supply. Absolute maximum V+ to V− is 7.0 V. Bypass locally to V−. |+| 5 | +IN B | input | Non-inverting input of amplifier channel B. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V. |+| 6 | -IN B | input | Inverting input of amplifier channel B. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V. |+| 7 | OUT B | output | Output of amplifier channel B. Rail-to-rail output stage. |+| 8 | OUT C | output | Output of amplifier channel C. Rail-to-rail output stage. |+| 9 | -IN C | input | Inverting input of amplifier channel C. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V. |+| 10 | +IN C | input | Non-inverting input of amplifier channel C. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V. |+| 11 | V- | power_in | Negative supply / ground rail. Tie to GND for single-supply operation or to the negative rail for dual supply. Absolute maximum V+ to V− is 7.0 V. |+| 12 | +IN D | input | Non-inverting input of amplifier channel D. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V. |+| 13 | -IN D | input | Inverting input of amplifier channel D. Rail-to-rail common-mode range from (V−)−0.1 V to (V+)+0.1 V. |+| 14 | OUT D | output | Output of amplifier channel D. Rail-to-rail output stage. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | TSSOP-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `RS8554XQXQ`+- `RS8554XQXP`++## CAD (KiCad official)++- Symbol: `RS8554XQ`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu RUNIC Tech datasheet](docs/rs8554xq-datasheet.pdf) (14 pp, sha256 `b3b02c9fa92c42d7`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
