Analog Devices AD Converter: Utilizes the AD7172-2 in single conversion mode. Please tell me the operation from writing the conversion start command (to register 0X01) to the first data output (issue /RDY signal pulse).
The operation after writing the conversion start to the register is as follows.
(1) Delay time set for startup
(2) Settling time (reset the internal digital filter. 1/MCLK x 64 x 5 = 160 μS)
(3) If the data rate is 2.6Ksps or more with the Sinc5 + Sinc1 filter, the time is 1/data rate x 5,
Sinc5 + Sinc1 filter, if data rate is 2.6Ksps or less, 1/data rate time,
Sinc3 filter issues /RDY signal pulse after 1/data rate x 3 time
* Sinc5 + Sinc1 filter: Acquire data 5 times at 31.25Ksps and process the moving average filter. If the output data rate is less than 2.6Ksps, then adjust the data rate and output.
