Working Principles

The MAX5414EUD+ is based on a digital potentiometer integrated circuit. It consists of a resistive ladder network and a wiper that can be digitally controlled. The resistance between the wiper terminal and either end terminal can be adjusted by sending appropriate commands through the serial I2C interface. The non-volatile memory ensures that the wiper position is retained even when power is off.

Detailed Application Field Plans

• Audio equipment: Volume control, tone adjustment
• Instrumentation: Calibration, signal conditioning
• Industrial automation: Process control, feedback adjustment
• Test and measurement: Programmable resistance loads, calibration
• Consumer electronics: Display brightness control, user interface adjustment
