BUILDING A “WINDOW” DAC
Some sensor applications require very high resolution
around the set point or threshold voltage.
Example 8-2 shows an example of creating a “window”
around the threshold using a voltage divider network
with a pull-up and pull-down resistor. In the circuit, the
output voltage range is scaled down, but its step reso-
lution is increased greatly.
EXAMPLE 8-2:
Single-Supply “Window” DAC.
