onsemi CAT5119TBI-50GT3

CAT5110/18/19/23/24/25 linear-taper digital POTs 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. The CAT5110 and CAT5125 are configured as potentiometers. The CAT5118/19/23/24 are configured as variable resistors. Three resistance values are available: 10 kΩ, 50 kΩ and 100 kΩ. All 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.
