This is a digitally controllable electronic potentiometer. The heart of the circuit is a 16 channel analog multiplexer. Controlled by the BCD value at the inputs, the output pin of the multiplexer ...

The key to the circuit is the low-power, digital-potentiometer 100-kΩ IC3 . Configured as a voltage divider, this IC provides an output of 32 discrete voltage steps between its minimum and maximum ...

Digital potentiometers with internal non-volatile memory can provide the benefit of powering-up a switched-mode power supply with an accurate, predefined output voltage. To accomplish ...
