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 | Amplifier A output. Rail-to-rail push-pull CMOS output; swings within ~7mV of the rails at RL=10kOhm and delivers ~80mA short-circuit current. |+| 2 | -IN A | input | Inverting input of amplifier A. High-impedance CMOS input, IB ~1pA typical, common-mode range -0.1V to +5.6V at Vs=5.5V. Diode-clamped to the supply rails. |+| 3 | +IN A | input | Non-inverting input of amplifier A. High-impedance CMOS input, rail-to-rail common-mode range (-0.1V to Vs+0.1V). Input signals more than 0.5V beyond the rails must be current-limited to 10mA. |+| 4 | V- | power_in | Negative supply / ground. In single-supply operation tie to GND; in split-supply operation connect to the negative rail. Total supply span V+ to V- must not exceed 7.0V (absolute maximum). |+| 5 | +IN B | input | Non-inverting input of amplifier B. High-impedance CMOS input, rail-to-rail common-mode range (-0.1V to Vs+0.1V). |+| 6 | -IN B | input | Inverting input of amplifier B. High-impedance CMOS input, IB ~1pA typical. |+| 7 | OUT B | output | Amplifier B output. Rail-to-rail push-pull CMOS output; ~80mA short-circuit current, unity-gain stable driving CL=100pF. |+| 8 | V+ | power_in | Positive supply. Operating range +2.5V to +5.5V referenced to V-. Bypass with a 0.1uF ceramic (and 10uF bulk) placed close to the pin per the datasheet layout guidance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `RS522XKXK`+- `RS522XKXM`++## CAD (KiCad official)++- Symbol: `RS522XK`+- 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/rs522xk-datasheet.pdf) (14 pp, sha256 `c8e86d17f4ba6f0a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
