Circuit Description
A/D Converter
The is composed of a 6 bit comparator,
filter, and 9 bit up/down counter. The 6 of
the 9 bit counter generate a reference signal to the
comparator. temperature or back-up
voltage is sensed by comparing output
voltage to the comparator with the thermistor
input voltage which originates as an
output signal from the It then supplies the
proper strobe pulse to the The thermistor
input voltage operates within a range of 1
