Figure 6. Digital to Analog and Analog to Digital Converter
DIGITAL TO ANALOG CONVERSION
The digital eightbit word to be converted is applied to the
inputs of the MC14512 with the most significant bit at X7
and the least significant bit at X0. A clock input of up to
2.5 MHz (at V
DD
= 10 V) is applied to the MC14520B.
A compromise between I
bias
for the MC1710 and R be-
tween N and Pchannel outputs gives a value of R of 33 k .
In order to filter out the switching frequencies, RC should
be about 1.0 ms (if R = 33 k , C
dB bandwidth would then be dc to 1.0 kHz.
0.03 F). The analog 3.0
ANALOG TO DIGITAL CONVERSION
An analog signal is applied to the analog input of the
MC1710. A digital eightbit word known to represent a dig-
itized level less than the analog input is applied to the
MC14512 as in the D to A conversion. The word is increm-
ented at rates sufficient to allow steady state to be reached
between incrementations (i.e. 3.0 ms). The output of the
MC1710 will change when the digital input represents the
first digitized level above the analog input. This word is the
digital representation of the analog word.
