10-Bit, Multichannel ADCs/DACs with FIFO,
Temperature Sensing, and GPIO Ports

Do not issue a second
CNVST signal before EOC goes
low; otherwise, the FIFO can be corrupted. Wait until all
conversions are complete before reading the FIFO. SPI
communications to the DAC and GPIO registers are per-
mitted during conversion. However, coupled noise may
result in degraded ADC signal-to-noise ratio (SNR).
Externally Timed Acquisitions and
Internally Timed Conversions with
CNVST
ADC Conversions in Clock Mode 01
In clock mode 01, conversions are requested one at a
time using
CNVST and performed automatically using
the internal oscillator. See Figure 7 for clock mode 01
timing after a command byte is issued.
Setting
CNVST low begins an acquisition, wakes up the
ADC, and places it in track mode. Hold
CNVST low for
at least 1.4s to complete the acquisition. If reference
mode 00 or 10 is selected, an additional 45s is
required for the internal reference to power up. If a tem-
perature measurement is being requested, reference
power-up and temperature measurement is internally
timed. In this case, hold
CNVST low for at least 40s.
Set
CNVST high to begin a conversion. Sampling is
completed approximately 500ns after
CNVST goes
high. After the conversion is complete, the ADC shuts
down and pulls
EOC low. EOC stays low until CS or
CNVST is pulled low again. Wait until EOC goes low
before pulling
CS or CNVST low. The number of CNVST
signals must equal the number of conversions request-
ed by the scan and averaging registers to correctly
update the FIFO. Wait until all conversions are com-
plete before reading the FIFO. SPI communications to
the DAC and GPIO registers are permitted during con-
(UP TO 514 INTERNALLY CLOCKED ACQUISITIONS AND CONVERSIONS)
