Summary
I²C-controlled digital potentiometer using the Maxim DS3502 chip.
Description
The **Maxim DS3502 Potentiometer** is a digitally controlled variable resistor that can be set via I²C communication. It allows precise adjustment of resistance for calibration, signal scaling, or user-configurable circuits. It supports both volatile and non-volatile operation depending on the Non-Volatile property.
Diagram:
Properties
- Enabled – Enables or disables the potentiometer.
- Initial Value – Sets the default resistance position.
- Non Volatile (boolean) – Determines if the potentiometer retains its value after power-off.
Pins
Input Pins
- In (analog) – Analog input to set the resistance.
- Control (i2c) – I²C interface for reading/writing the potentiometer value.
