Digital pots interface directly with quadrature encoders, push buttons and MCUs

LSI Computer Systems (LSI/CSI) has created a family of 63 tap (6bit) digital potentiometers for direct connection to quadrature decoders, push buttons, GPIOs or SPI serial controls. Debounce circuits are included where electromechanical switches are expected, although external pull-up resistors must be added. “The LSI/CSI digital potentiometers are used as replacements for mechanical potentiometers and for potentiometer ...
