The AD5228BUJZ10-RL7 is a 32-position Manual Up/Down Control Potentiometer emulating mechanical potentiometer operation. Its simple up/down control interface allows manual control with just two external pushbutton tactile switches. It is designed with a built-in adaptive debouncer that ignores invalid bounces due to contact bounce commonly found in mechanical switches. The debouncer is adaptive, accommodating a variety of pushbutton tactile switches that generally have less than 10ms of bounce time during contact closures. When choosing the switch, the user should consult the timing specification of the switch to ensure its suitability in an AD5228 application. The AD5228 can increment or decrement the resistance in discrete steps or in auto scan mode. The resistance changes by one step when the PU or PD button is pressed briefly (no longer than 0.6s).
