MAX11212
Data Read Following Every Conversion
The MAX11212 indicates conversion data availabil-
ity as well as allows the retrieval of data through the
RDY/DOUT output. The RDY/DOUT output idles at the
value of the last bit read unless a 25th SCLK pulse is
provided, causing RDY/DOUT to idle high. RDY/DOUT is
pulled low when the conversion data is available.
Figure 1 shows the timing diagram for the data read.
Once a low is detected on RDY/DOUT, clock pulses at
SCLK clock out the data. Data is shifted out MSB first
and is in binary two’s complement format. Once all the
data has been shifted out, a 25th SCLK is required to
pull the RDY/DOUT output back to the idle high state.
See Figure 2.
If the data is not read before the next conversion data is
updated, the old data is lost, as the new data overwrites
the old value.
Data Read Followed by Self-Calibration
To initiate self-calibration at the end of a data read,
provide a 26th SCLK pulse. After reading the 16 bits of
conversion data, a 25th positive edge on SCLK pulls
the RDY/DOUT output back high, indicating end of data
read. Provide a 26th SCLK pulse to initiate a self-calibra-
tion routine starting on the falling edge of the 26th SCLK.
A subsequent falling edge of RDY/DOUT indicates data
availability at the end of calibration. The timing is illus-
trated in Figure 3.
