Hi.
I am using 12bit ADC, Texas Instruments ADS5295.
Table 20 on page 75 of the manual shows that ads5295 supports 14x serialization and has to be used with digital processing function (such as averaging and decimation filter).
However, there is only a timing diagram for 10x and 12x serialization in the manual and no timing diagram for 14x serialization.
My question is
1. ADS5295 has 12bit resolution. If i use 14x serialization, how can 12bit data be 14bit? Are two zero padding bits added? Or is it changed to 14bits by digital filter?
2. If it is correct to change by digital filter, please tell me more about which filter to use. (averaging filter? decimation filter? both?)
Thanks
