AD8531ARZ

UMW · Operational Amplifier · SOP-8

AD8531ARZ from UMW, in a SOP-8. 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 NC unconnected No connect. 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.

  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ad8531arz-etched.step / ad8531arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad8531arz.step / ad8531arz.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: UMW datasheet (21 pp, sha256 7911ec8741aab739, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
