CAT5120, CAT5121, CAT5122

16-Tap MiniPot™ Digitally Programmable

Potentiometers with 2-Wire Interface

FEATURES

0.3µA Ultra-low standby 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 SC-70 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.

Three resistance values are available: 10kΩ, 50kΩ and

100kΩ. These are available in space-saving 5-pin and

6-pin SC-70 and SOT-23 packages.

APPLICATIONS

LCD screen adjustment

Volume control

Mechanical potentiometer replacement

Gain adjustment

Line impedance matching

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.
