Figure 59. Multiple Converters Connected Using Chain Mode
When multiple converters are used in chain mode, the first converter is configured in regular mode while the rest
of the converters downstream are configured in chain mode. When a converter is configured in chain mode, the
CDI input data goes straight to the output register, therefore the serial input data passes through the converter
with a 16 SCLK (if the TAG feature is disabled) or a 24 SCLK delay, as long as CS is active. See
Figure 60
for
detailed timing. In this timing the conversion in each converters are done simultaneously.
