MAXIM INTEGRATED / ANALOG DEVICES DS1809Z-010+ Datasheet & Stock

The DS1809Z-010+ is a Dallastat non-volatile digitally controlled potentiometer in 8 pin NSOIC package. This device provides simple contact closure controlled interface and microprocessor controlled interface. Wiper position is maintained in the absence of power in EEPROM. The device provides two methods of non-volatile wiper storage using internal EEPROM memory cells. These two methods include an auto store configuration and a command initiated storage operation which is processed utilizing the STR input pin. The EEPROM cell array of the DS1809 is designed to accept greater than 50k writes. It handles both mechanical pushbutton and digital inputs, hence DS1809 can adapt to applications with either or both mechanical and processor controlled interfaces.
