32-Tap MiniPott Digitally
Programmable Potentiome-
ters with 2-Wire Interface
Description
potentiometers perform the same function as a mechanical
potentiometer or a variable resistor. These devices consist of a fixed
resistor and a wiper contact with 32−tap points that are digitally
controlled through a 2−wire up/down serial interface.
CAT5118/19/23/24 are configured as variable resistors.
devices are available in space−saving 5−pin and 6−pin SOT−23
packages. The CAT5110/18/19 are also available in the SC−70
package.
