A digital potentiometer, often referred to as a “digipot,” is an electronic component that emulates the functionality of a traditional mechanical potentiometer (variable resistor) using digital control. Instead of manually turning a physical knob or slider to adjust resistance, a digital potentiometer allows you to change its resistance value electronically through digital signals.

The AS1501 is a digital potentiometer with 256 programmable steps. The values of the resistor can be
controlled via 3 wire serial interface capable to handle programming rates up to 10MHz.

The AS1500 is available in four different resistor values. The AS1500 incorporates a 10kΩ, the AS1501 a 20kΩ, the AS1502 a 50kΩ and the AS1503 a 100kΩ fixed resistor. […]
