Description
The DS1869S-100+T&R is a digital rheostat or potentiometer, known as the DallastatTM. It features 64 possible uniform tap points over the resistive range of either 10 kΩ, 50 kΩ, or 100 kΩ. This electronic component can be controlled using a switch contact closure input or a digital source input such as a CPU. It operates with power supplies of either 3V or 5V. The wiper position of the DS1869S-100+T&R is maintained even in the absence of power thanks to an EEPROM memory cell array that can withstand more than 50,000 writes.
