The Intersil X60250 combines a temperature compensated voltage reference with a Intersil Digitally Controlled Potentiometer (XDCP) to provide a precision adjustable reference with a range of 0.0V to 1.25V. The X60250 includes a serial bus interface to enable in-circuit programming of the reference voltage.
The X60250 contains a resistor chain with 255 taps to provide 8 bits of digital adjustment to the reference voltage. Non-volatile storage retains the digital wiper setting, for permanent reference programming. An additional matched 100k resistor is available to increase resolution of the output voltage while retaining accuracy.
