Figure 5. Digital to Analog and Analog to Digital Converter
DIGITAL TO ANALOG CONVERSION
The digital eight–bit 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 VDD = 10 V) is applied to the MC14520B.
A compromise between Ibias for the MC1710 and
R
between N and P–channel outputs gives a value of R of
33 k ohms. In order to filter out the switching frequencies,
RC should be about 1.0 ms (if R = 33 k ohms,
C
0.03
μ
F). The analog 3.0 dB bandwidth would then be
dc to 1.0 kHz.
ANALOG TO DIGITAL CONVERSION
An analog signal is applied to the analog input of the
MC1710. A digital eight–bit word known to represent a digi-
tized 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.
