TQFP package is 16bit
QFN package is 24bit
It is described in the specification as described above.
However, the QFN package also behaves like 16-bit resolution.
I want you to give correct information.

Hi,

I apologize for the confusion, can you tell me where it is described this way so that we can fix it and avoid this in the future?

The devices bio-potential devices with a 1 as the second numerical digit are 16 bit, such as ADS1191, the devices with a 2 as the second numerical digit are 24 bit, such as ADS1291.
