Rail-to-rail output stage; drives loads down to 2kΩ, output short-circuit current ~46mA. |+| 2 | -INA | input | Amplifier A inverting input. Common-mode input range (V-)-0.2V to (V+)+0.2V; input bias current ~10pA. |+| 3 | +INA | input | Amplifier A non-inverting input. Rail-to-rail input capability; input bias current ~10pA. |+| 4 | V- | power_in | Negative supply / ground. Supply voltage (V+)-(V-) is 1.8V to 5.5V; absolute maximum 6V. |+| 5 | +INB | input | Amplifier B non-inverting input. Rail-to-rail input capability; input bias current ~10pA. |+| 6 | -INB | input | Amplifier B inverting input. Common-mode input range (V-)-0.2V to (V+)+0.2V; input bias current ~10pA. |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage; drives loads down to 2kΩ, output short-circuit current ~46mA. |+| 8 | V+ | power_in | Positive supply. Single supply 1.8V to 5.5V referenced to V-; absolute maximum (V+)-(V-) = 6V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | WILLSEMI Will Semicon |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `WS72358M-8/TR`+- `WS72358M-8S-8/TR`++## CAD (KiCad official)++- Symbol: `WS72358M-8`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [WILLSEMI Will Semicon datasheet](docs/ws72358m-8-datasheet.pdf) (12 pp, sha256 `0e7700e3ab6d8595`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
