1 / 10 page General Description The DS1805 addressable digital potentiometer contains a single 256-position digitally controlled potentiometer. Device control is achieved through a 2-wire serial inter- face. Device addressing is provided through three address inputs that allow up to eight devices on a sin- gle 2-wire bus. The exact wiper position of the poten- tiometer 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 val- ues: 10k Ω, 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.
