GENERAL DESCRIPTION
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 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. APPLICATIONS
