AD5258BRMZ1 Datasheet PDF - ADI

●The AD5258BRMZ1 is a non-volatile Digital Potentiometer performs the same electronic adjustment function as mechanical potentiometers or variable resistors, but with enhanced resolution and solid-state reliability. The wiper settings are controllable through an I²C-compatible digital interface that is also used to read back the wiper register and EEPROM content in addition, resistor tolerance is stored within EEPROM, providing an end-to-end tolerance accuracy of 0.1%. There is also a software write protection function that ensures data cannot be written to the EEPROM register. A separate VLOGIC pin delivers increased interface flexibility.

● Non-volatile memory stores wiper setting

● VLOGIC pin provides increased interface flexibility

● Resistance tolerance stored in EEPROM (0.1% accuracy)

● power-ON EEPROM refresh time <1ms

● Software write protect command
