DESCRIPTION

CAT5110/18/19/23/24/25 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: 10k?, 50k? and 100k?

■ Low wiper resistance: 80? for CAT5123, CAT5124, CAT5125

■ CAT5110, CAT5118, CAT5119 available in SC-70

APPLICATIONS

■ LCD screen adjustment

■ Volume control

■ Mechanical potentiometer replacement

■ Gain adjustment

■ Line impedance matching
