Leave floating or tie to any convenient potential; not internally bonded. |+| 2 | -INA | input | Inverting input of amplifier A. Rail-to-rail input; common-mode range 0 V to Vs. Input bias current typ 5 pA. |+| 3 | +INA | input | Non-inverting input of amplifier A. Rail-to-rail input; common-mode range 0 V to Vs. Input bias current typ 5 pA. |+| 4 | V- | power_in | Negative supply rail (ground in single-supply operation). Total supply voltage V+ − V- must be between 2.7 V and 6 V (7 V absolute max). |+| 5 | NC | unconnected | No connect. Leave floating or tie to any convenient potential; not internally bonded. |+| 6 | OUTA | output | Amplifier A output. Rail-to-rail output capable of sourcing/sinking ±250 mA. Closed-loop output impedance 40-60 Ω at 1 MHz (Av=1). |+| 7 | V+ | power_in | Positive supply rail. Single-supply operation from 2.7 V to 6 V (7 V absolute max). Supply current typ 0.75 mA at 5 V. |+| 8 | NC | unconnected | No connect. Leave floating or tie to any convenient potential; not internally bonded. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `AD8531ARZARZ`+- `AD8531ARZAR`+- `AD8531ARZKS`+- `AD8531ARZRT`++## CAD (KiCad official)++- Symbol: `AD8531ARZ`+- 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:** [UMW datasheet](docs/ad8531arz-datasheet.pdf) (21 pp, sha256 `7911ec8741aab739`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
