Digital Potentiometers (DigiPOT)
Analog Devices portfolio of digital potentiometers provide uncompromising performance across a wide range of industrial temperatures. Sometimes called digital pots, RDACs, or digiPOTs, these compact devices can be used to calibrate system tolerances or dynamically control system parameters. DigiPOTs such as the AD5123 and AD5143 offer a nonvolative solution for 128-position/256-position adjustment applications, with low resistor tolerance and the low temperature coefficient simplifying open-loop applications and those that require tolerance matching.

Frequently Asked Questions
- Can I read back the contents of the two RDAC registers of AD5242 or AD5282 (dual I2C compatible digital potentiometer)?
- For dual supply digital potentiometers, if VDD/VSS are +2.5V/-2.5V respectively, can digital inputs be fed from a standard 3.3V CMOS logic component without logic level translation? What are the logic level thresholds when VDD is +2.5V and VSS is -2.5V?
