CAT5124

CAT5110, CAT5118, CAT5119, CAT5123, CAT5124, CAT5125 32‐tap Digital Potentiometers (POTs) with 2‐wire Interface Description 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 kW, 50 kW and 100 kW. 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.
