Requires external pull-up resistor (RPU typ. 5.1kΩ). VOL typ. 150mV at IO≤4mA; output pull-up voltage range up to 5.6V. |+| 2 | -INA | input | Inverting input, channel A. Input common-mode range (V-)-0.1 to (V+)+0.1 V; input bias current typ. 1 pA. |+| 3 | +INA | input | Noninverting input, channel A. Input common-mode range includes ground; input bias current typ. 1 pA. |+| 4 | V- | power_in | Negative (lowest) power supply. Typically GND for single-supply operation (1.8V to 5.5V) or -2.75V for dual-supply operation. |+| 5 | +INB | input | Noninverting input, channel B. Input common-mode range includes ground; input bias current typ. 1 pA. |+| 6 | -INB | input | Inverting input, channel B. Input common-mode range (V-)-0.1 to (V+)+0.1 V; input bias current typ. 1 pA. |+| 7 | OUTB | output | Open-drain output of channel B. Requires external pull-up resistor (RPU typ. 5.1kΩ). VOL typ. 150mV at IO≤4mA; output pull-up voltage range up to 5.6V. |+| 8 | V+ | power_in | Positive (highest) power supply. Operating range 1.8V to 5.5V (single-supply); absolute maximum 7V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu RUNIC Tech |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `RS393XK`+- `RS393XKXF`+- `RS393XKXP`+- `RS393XKXQ`++## CAD (KiCad official)++- Symbol: `RS393XK`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Jiangsu RUNIC Tech datasheet](docs/rs393xk-datasheet.pdf) (16 pp, sha256 `92fbba6bb4adde8a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
