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
A compromise between I
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 F).
The analog 3.0 dB bandwidth would then be dc to 1.0 kHz.
ANALOG TO DIGITAL CONVERSION
MC1710. A digital eight–bit 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.
The digital eight–bit word to be converted is applied to the
