AD5252 - Dual 64-/256-Position I2C Nonvolatile Memory Digital Potentiometers

This page provides the datasheet information for the AD5252, a member of the AD5251 Dual 64-/256-Position I2C Nonvolatile Memory Digital Potentiometers family.

Datasheet Summary

Description

The AD5251/AD52521 are dual-channel, I2C, nonvolatile memory, digitally controlled potentiometers with 64/256 positions, respectively.

These devices perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors.

Features

  • AD5251: Dual 64-position resolution.
  • AD5252: Dual 256-position resolution.
  • AD5251: 50 kΩ.
  • AD5252: 1 kΩ, 10 kΩ, 50 kΩ, 100 kΩ.
  • Nonvolatile memory stores wiper setting w/write protection.
  • Power-on refreshed with EEMEM settings in 300 µs typ.
  • EEMEM rewrite time = 540 µs typ.
  • Resistance tolerance stored in nonvolatile memory.
  • 12 extra bytes in EEMEM for user-defined information.
  • I2C compatible serial interface.
  • Direct read/write access of RDAC.
