10-Bit 300ksps ADCs with FIFO,
Temp Sensor, Internal Reference
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 MAX1026/MAX1028/MAX1030 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. If
a temperature measurement is requested, the tempera-
ture result precedes all other FIFO results. EOC stays
low until CS is pulled low again.
