DEscription
CAT5110/5118/5119/5123/5124/5125 linear-taper digitally programmable 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. The CAT5110 and CAT5125 are configured as potentiometers. The CAT5118/19/23/24 are configured as variable resistors. Three resistance values are available: 10kΩ, 50kΩ and 100kΩ. All devices are available in space-saving 5-pin and 6-pin SOT-23 packages. The CAT5110/5118/5119 are also available in the SC70 package.
0.3µA Ultra-low standby current Single-supply operation: 2.7V to 5.5V Glitchless switching between resistor taps Power-on reset to midscale 2-Wire up/down serial interface Resistance values: 10kΩ, 50kΩ and 100kΩ All devices available in SOT-23 package CAT5110, CAT5118, CAT5119 also available in SC70
