32-Tap Digital Potentiometers
with 2-Wire Interface
Description
DP7110/18/19/23/24/25 lineaUïtaper digital 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 32ïtap points that are digitally
controlled through a 2ïwire up/down serial interface.
The DP7110 and DP7125 are configured as potentiometers. The
DP7118/19/23/24 are configured as variable resistors.
Three resistance values are available: 10 k , 50 k and 100 k . All
devices are available in spaceïsaving 5ïpin and 6ïpin SOTï23
packages. The DP7110/18/19 are also available in the SCï70
package.
