16-Tap MiniPot™ Digitally Programmable
Potentiometers with 2-Wire Interface
Features
0.3µA Ultra-low supply 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
Available in SC70 and SOT-23 packages
DEscription
CAT5120/5121/5122 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 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.
Applications
LCD screen adjustment
Volume control
Mechanical potentiometer replacement
Gain adjustment
Line impedance matching
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.

the wiper position.
Chip Select Input.Ahigh-to-low CS transition
determines the mode: increment if U/D is
high, or decrement if U/D is low.
