32-Tap Digital Potentiometers

with 2-Wire Interface

Description

DP7110/18/19/23/24/25

linea taper

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 32 tap points that are digitally

controlled through a 2 wire 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 space saving 5 pin and 6 pin SOT 23

packages. The DP7110/18/19 are also available in the SC 70

package.
