Worst case large signal transition.
Guaranteed monotonic.
Gives <1 bit additional error under nominal conditions
Conversion time =
either MCLK/8 or MCLK/16, as shown in the table below:
A-D Clock Frequency:
Conversion Time:
Due to latency in the control logic, the maximum sample rate is lower than this. Refer to the
Output Rate details in the Receive Parameters section.
No missing codes.
Measured at 3.3V supply voltage.
