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 | Op-amp A output. Rail-to-rail output stage, source ~85mA / sink ~125mA into RL=1kohm. Output swing from rail ~23mV at RL=1kohm. |+| 2 | -IN A | input | Op-amp A inverting input. CMOS input, typical Vos 1.5mV, IB ~1pA. Input range -0.2V to 3.9V with Vs=5V; inputs are diode-clamped to the rails and should be current-limited to <=10mA if driven >0.5V beyond the rails. |+| 3 | +IN A | input | Op-amp A non-inverting input. CMOS input, typical Vos 1.5mV, IB ~1pA. Common-mode range -0.2V to 3.9V with Vs=5V; CMRR typically 85dB. |+| 4 | V- | power_in | Negative supply rail (or ground for single-supply operation). Total supply V+ to V- from 2.5V to 5.5V (absolute max 7.0V). Shared by both amplifiers. |+| 5 | +IN B | input | Op-amp B non-inverting input. CMOS input, typical Vos 1.5mV, IB ~1pA. Common-mode range -0.2V to 3.9V with Vs=5V. |+| 6 | -IN B | input | Op-amp B inverting input. CMOS input, typical Vos 1.5mV, IB ~1pA. Diode-clamped to the supply rails. |+| 7 | OUT B | output | Op-amp B output. Rail-to-rail output, source ~85mA / sink ~125mA into RL=1kohm. Slew rate 180V/us, 250MHz gain-bandwidth product. |+| 8 | V+ | power_in | Positive supply rail. Operating range 2.5V to 5.5V (absolute max 7.0V V+ to V-). Quiescent current ~2.9mA per amplifier typ; PSRR ~90dB. Bypass with a local 100nF ceramic to V-. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `RS8752XKXK`+- `RS8752XKXM`+- `RS8752XKXT`+- `RS8752XKXQ`++## CAD (KiCad official)++- Symbol: `RS8752XK`+- 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:** [Jiangsu RUNIC Tech datasheet](docs/rs8752xk-datasheet.pdf) (14 pp, sha256 `172c25f6fd9af546`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
