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.
Available in SC.
70 and SOT.
23 Packages.
These Devices are Pb-Free, Halogen Fre.

CAT5120, CAT5121, CAT5122 16‐tap Digital Potentiometers (POTs) with 2‐wire Interface Description CAT5120/5121/5122 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 16-tap points that are digitally controlled through a 2-wire up/down serial interface. The CAT5120 is configured as a potentiometer. The CAT5121 and CAT5122 are configured as variable resistors. See Pin Configurations for part functionality. Two resistance values are available: 10 kW and 50 kW. These are available in space-saving 5-pin and 6-pin SC−70 and SOT−23 packages. Features  0.3 mA Ultra-low Standby Current  Single-supply Operation: 2.7 V to 5.
