CAT5121 fiche technique
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 SC70 and SOT23
packages.
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 SC70 and SOT23 Packages
These Devices are Pb-Free, Halogen Free/BFR Free and are RoHS
Compliant
Applications
LCD Screen Adjustment
Volume Control
