Dual Precision Voltage Reference
A dual OP200 and a REF43, a 2.5 V reference, can be used to
build a ±2.5 V precision voltage reference. Maximum output
current from each reference is ±10 mA with load regulation
under 25 µV/mA. Line regulation is better than 15 µV/V and
output voltage drift is under 20 µV/°C. Output voltage noise
from 0.1 Hz to 10 Hz is typically 75 µV p-p. R1 and D1 ensure
correct start-up.
Programmable High Resolution Window Comparator
The programmable window comparator shown in Figure 9 is
easily capable of 12-bit accuracy over the full military tempera-
ture range. A dual CMOS 12-bit DAC, the DAC8212, is used
in the voltage switching mode to set the upper and lower thresh-
olds (DAC A and DAC B, respectively).
