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.
Features
0.3 mA Ultra-low Standby Current
Single-supply Operation: 2.7 V to 5.5 V
Glitchless Switching between Resistor Taps
Power-on Reset to Midscale
2-wire Up/Down Serial Interface
Resistance Values: 10 kW, 50 kW and 100 kW
Low Wiper Resistance: 80 W for CAT5123, CAT5124, CAT5125
CAT5110, CAT5118, CAT5119 Available in SC−70
These Devices are Pb-Free, Halogen Free/BFR Free and are RoHS
Compliant
