Analog Devices AD5255 3-Channel Digital Potentiometer Datasheet
The AD5255 is a 3-channel digitally controlled variable resistor (RDAC) available in a 24-lead TSSOP package. It provides two dual 512-position channels and one single 128-position channel, offering full-scale resistances of either 25 kΩ or 250 kΩ with 1% channel-to-channel matching tolerance.
The device features a standard I²C-compatible serial interface for wiper programming, EEPROM reading, and writing. It includes 256 bytes of general-purpose user EEPROM and 11 bytes of RDAC-specific user EEPROM to retain settings during power cycles. The AD5255 operates on single-supply voltages from 2.7 V to 5.5 V or dual supplies from ±2.25 V to ±2.75 V over an industrial temperature range of -40°C to +85°C.
