MAXIM INTEGRATED / ANALOG DEVICES DS1809U100 Digital Potentiometer

The DS1809U-100+ is a digitally controlled, non-volatile potentiometer in an 8-pin µSOP package, manufactured by Maxim Integrated Products. It features a 64-position linear potentiometer with a resistance of 100kΩ ±20%. The device provides both digital and pushbutton control interfaces, allowing flexible adjustment of the wiper position. The wiper position is retained in EEPROM memory even when power is off, with two non-volatile storage methods: auto store and command-initiated storage via the STR input. It is suitable for automation and process control applications, offering a cost-effective alternative to mechanical potentiometers. The device operates with a supply voltage of 4.5V to 5.5V, consumes approximately 500µA during active operation, and 25µA in standby. Its operating temperature range is from -40°C to 85°C. The wiper has a resistance of 400 ohms, with a maximum wiper current of 1mA and a minimum storage time of 4ms. The device provides uniform wiper positioning across the entire resistance range and features a temperature coefficient of 750ppm/°C.
