Internally Timed Acquisitions and
Conversions Using
CNVST
Performing Conversions in Clock Mode 00
In clock mode 00, the wake up, acquisition, conversion,
and shutdown sequences are initiated through
CNVST
and performed automatically using the internal oscilla-
tor. Results are added to the internal FIFO to be read
out later. See Figure 4 for clock mode 00 timing.
Initiate a scan by setting
CNVST low for at least 40ns
before pulling it high again. The MAX1026/MAX1028/
MAX1030 then wake 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. Wait until
EOC goes low before
pulling
CS low to communicate with the serial interface.
EOC stays low until CS or CNVST is pulled low again. A
temperature measurement result, if requested, pre-
cedes all other FIFO results.
Do not initiate a second
CNVST before EOC goes low;
otherwise, the FIFO can become corrupted.
Externally Timed Acquisitions and
Internally Timed Conversions with
CNVST
Performing 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 5 for clock mode 01
timing.
Setting
CNVST low begins an acquisition, wakes up the
ADC, and places it in track mode. Hold
CNVST low for
at least 1.4μs to complete the acquisition. If the internal
reference needs to wake up, an additional 65μs is
required for the internal reference to power up. If a tem-
perature measurement is being requested, reference
power-up and temperature measurement are internally
timed. In this case, hold
CNVST low for at least 40ns.
Set
CNVST high to begin a conversion. After the con-
version 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.
If averaging is turned on, multiple
CNVST pulses need
to be performed before a result is written to the FIFO.
Once the proper number of conversions has been per-
formed to generate an averaged FIFO result, as speci-
fied by the averaging register, the scan logic
automatically switches the analog input multiplexer to
the next-requested channel. If a temperature measure-
ment is programmed, it is performed after the first rising
edge of
CNVST following the input data byte written to
the conversion register. The result is available on DOUT
once
EOC has been pulled low.
