ABSTRACT:
An integrated circuit containing two digital potentiometers with each potentiometer including a passive resistor string with tap points. Tap point selection is programmed through a three-wire serial port. An output multiplexing the selected tap points permits tying the two potentiometers in series to form a single potentiometer of twice the size.
