Overview
DS1805 Rev 1; 9/06 Addressable Digital Potentiometer General Description The DS1805 addressable digital potentiometer contains a single 256-position digitally controlled potentiometer.
Device control is achieved through a 2-wire serial interface.
Device addressing is provided through three address inputs that allow up to eight devices on a single 2-wire bus.
The exact wiper position of the potentiometer can be written or read.
The DS1805 is available in 16-pin SO and 14-pin TSSOP packages.
The device is available in three standard resistance values: 10kΩ, 50kΩ, and 100kΩ.
The DS1805 is specified over the industrial temperature range.
The DS1805 provides a low-cost alternative for designs based on the DS1803, but require only a single potentiometer.
