Overview

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.

  • 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
