reset
The ADC and DAC portions of the PCM3008 can be reset simultaneously by the power down control pins, PDAD
and PDDA. This external reset using PDAD and PDDA must be always done at least once after the power is
applied. Internal state is kept in reset during PDAD = low and PDDA = low and for 1024 system clock counts
after PDAD = high or PDDA = high, and then the initialization sequence for ADC and DAC is started. For the
ADC, DOUT is kept in ZERO during the initialization sequence and DOUT outputs normal data corresponding
to the input analog signal after t
ADCDLY1
. In the case of the DAC, the fade-in function is started, the signal level
on V
OUT
increases gradually and reaches to full level corresponding to the input digital signal after t
DACDLY1
.
The following figure illustrates the reset timing for power-on and the ADC/DAC output response for the power-on
and reset sequence.
