Internally Timed Acquisitions and
Conversions Using the Serial Interface
Performing Conversions in Clock Mode 10
In clock mode 10, the wake-up, acquisition, conversion,
and shutdown sequences are initiated by writing an
input data byte to the conversion register, and are per-
formed automatically using the internal oscillator. This is
the default clock mode upon power-up. See Figure 6
for clock mode 10 timing.
Initiate a scan by writing a byte to the conversion regis-
ter. The MAX11634–MAX11637 then power up, scan all
requested channels, store the results in the FIFO, and
shut down. After the scan is complete, EOC is pulled
low and the results are available in the FIFO. EOC stays
low until CS is pulled low again.
Externally Clocked Acquisitions and
Conversions Using the Serial Interface
Performing Conversions in Clock Mode 11
In clock mode 11, acquisitions and conversions are ini-
tiated by writing to the conversion register and are per-
formed one at a time using the SCLK as the conversion
clock. Scanning and averaging are disabled, and the
conversion result is available at DOUT during the con-
version. See Figure 7 for clock mode 11 timing.
Initiate a conversion by writing a byte to the conversion
register followed by 16 SCLK cycles. If CS is pulsed
high between the eighth and ninth cycles, the pulse
width must be less than 100s. To continuously convert
at 16 cycles per conversion, alternate 1 byte of zeros
between each conversion byte.
