The WinPot WMS7201 is a single channel IC. The WinPot WMS7204 is a quad channel IC. Both chips feature 256-taps, a selectable output buffer and ultra-low standby current (1 μA maximum with output buffer inactive). The WMS7201 and the WMS7204 are available in 10 KΩ, 50 KΩ, and 100 KΩ resistance values. Both chips can be used as a three-terminal potentiometer or as a two terminal variable resistor.
