AD5231 - 1024-Position Digital Potentiometer

Datasheet Summary

Description

The AD5231 is a nonvolatile memory1, digitally controlled potentiometer2 with 1024-step resolution.

The device performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and remote controllability.

Features

  • 1024-position resolution.
  • Nonvolatile memory maintains wiper setting.
  • Power-on refresh with EEMEM setting.
  • EEMEM restore time: 140 µs typ.
  • Full monotonic operation.
  • 10 kΩ, 50 kΩ, and 100 kΩ terminal resistance.
  • Permanent memory write protection.
  • Wiper setting readback.
  • Predefined linear increment/decrement instructions.
  • Predefined ±6 dB/step log taper increment/decrement instruc- tions.
  • SPI®-compatible serial interface.
  • 3 V to 5 V sing.
