5.9. DAC & PWM
SNC352 is an advanced chip to be designed having two optimal methods to play out
the voices. One is DAC and the other is PWM. Upon user’s applications, user can
select either DAC or PWM in his design. Please be aware that only one method can
be activated at a time.
DAC
: A 7-bit current type digital-to-analog converter is built-in SNC352. The
relationship between input digital data and output analog current signal is listed in the
following table. Also, the recommended application circuit is illustrated as follows.
