Digital potentiometer - 4 bit, using common components
With a common components, you can implement a reliable, low-cost, CMOS digital potentiometer
for various applications. The result is a direct drop-in replacement for the wear-prone
mechanical potentiometer.
An examle is a potentiometer used by industrial applications where the wiper of
the potentiometer produces a signal of 0 to 10V for various controllers.
The solid-state unit provides a similar output of 0 to 10V and delivers as much as 10 mA to the controller.
