GENERAL DESCRIPTION

The AD5253/AD5254 are quad channel,2C, 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.

The AD5253/AD5254’s versatile programmability allows multiple modes of operation, including read/write accesses in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6 dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components, look-up table,or system identification information.
