DesCrIPTIOn
CAT520/52/522 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 6-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.
Three resistance values are available: 10kΩ, 50kΩ and
100kΩ. These are available in space-saving 5-pin and
6-pin SC70 and SOT-23 packages.

Description
Power Supply
Ground
Up/Down Control Input. With CS low, a low-
to-high transition increments or decrements
the wiper position.
Chip Select Input. A high-to-low CS transition
determines the mode: increment if U/D is
high, or decrement if U/D is low.
