Casio CZ-1 - Dac

17. DAC
(Digital to
Analog
Converter)
CIRCUIT
The two
Music LSIs
output
different waveforms.
When
signal
DOE
is HIGH,
Master LSI
outputs a
waveform
while
Slave
LSI
outputs a
waveform
at LOW
level of DOE.

Note: As
the
following figure
is an illustration
for
a
principle
of
the
time
sharing,
the
actual
waveforms differ.
Matter/Slave
LSI
are digital
signals,
not analog
ones.
