CAT5120TBI-10GT3 General Description

CAT5120 linear-taper digital POT performs the same function as a mechanical potentiometer or a variable resistor. This device consists of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire up/down serial interface.

The CAT5120 is configured as a potentiometer. See Pin Configurations for part functionality.

Three resistance values are available: 10 kΩ , 50k Ω and 100 kΩ.

Key Features

0.3 A Ultra-low Supply 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 kΩ, 50 kΩ and 100kΩ

Application

LCD Screen Adjustment
Volume Control
