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 | OUTA | output | Amplifier A output. Rail-to-rail output stage; can swing within ~5mV of VSS/VDD with a 10kΩ load. Short-circuit current limit typ. 60mA. |+| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA. |+| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA. |+| 4 | VSS | power_in | Negative supply / ground reference. For single-supply operation tie to GND; supply range 1.8V to 5.5V referenced to VDD (absolute max VDD-VSS = 7.5V). |+| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA. |+| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V), input bias current typ. 20pA. |+| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage; can swing within ~5mV of VSS/VDD with a 10kΩ load. Short-circuit current limit typ. 60mA. |+| 8 | VDD | power_in | Positive supply. Single-supply range 1.8V to 5.5V (dual ±0.9V to ±2.75V). Decouple with a 0.1µF ceramic close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `AD8552MM/TR`+- `AD8552MMM/TR`+- `AD8552MMDQ3/TR`++## CAD (KiCad official)++- Symbol: `AD8552MM`+- 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:** [HGSEMI datasheet](docs/ad8552mm-datasheet.pdf) (14 pp, sha256 `cc410ba754d21631`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
