Working Principles

The AD5201BRMZ10-REEL7 is a digital potentiometer that utilizes a resistor network and digital control to adjust the resistance value. The wiper terminal, controlled by the digital interface, moves along the resistor network, effectively changing the resistance between the A and B terminals. The non-volatile memory ensures that the wiper position is retained even when power is removed.

Detailed Application Field Plans

• Audio equipment: Volume control, tone adjustment
• Instrumentation: Calibration, signal conditioning
• Industrial automation: Control systems, feedback circuits
• Communication systems: Signal attenuation, impedance matching
• Automotive electronics: Climate control, lighting intensity adjustment
