Description

DIGIPOT 8BIT I2C EEMEM 50K 5254

The AD5253/AD5254 are quad-channel, I2C®, nonvolatile mem-ory, digitally controlled potentiometers with 64/256 positions, respectively. These devices perform the same electronic adjust-ment functions as mechanical potentiometers, trimmers, and variable resistors. The parts’ versatile programmability allows multiple modes of operation, including read/write access 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.
