DS1669-10 Digital POT

The DS1669 Dallastat™ is a single digital rheostat or potentiometer with access to all three potentiometer terminals. The potentiometer has 64 wiper positions with equal or linear resistive step sizes. This device has both positive and negative 8V (max) supply inputs for maximum wiper outputs of ±7.5V. The wiper position is stored in EEPROM for power-up in a known position or to save calibration information. Control access is configurable with a single pushbutton, dual pushbutton, or digital source input.
