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

Download the AD5252 datasheet PDF. This datasheet also covers the AD5251 variant, as both devices belong to the same dual 64-/256-position i2c nonvolatile memory digital potentiometers family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
