DESCRIPTION

CAT5110/5118/5119/5123/5124/5125 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 32-tap points that are digitally controlled through a 2-wire up/down serial 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

■ All devices available in sOT-23 package

■ CAT5110, CAT5118, CAT5119 also available in sC70

APPLICATIONS

■ LCD screen adjustment

■ Volume control

■ Mechanical potentiometer replacement

■ Gain adjustment

■ Line impedance matching
