Hi team,

Could you let me know why in ADS7953 datasheet, the gain error spec is max 2(LSB).

Normally for other ADCs, it's always something like 0.1%.

How do they convert with each other?

THank you!

Hi Luke,

Unfortunately I do not know why the author of the ADS7953 datasheet choose to show the gain error as LSB versus %FSR, but its rather easy to convert using the Analog Engineer's Calculator. For the 12-bit ADS7953, the 2 LSB MAX gain error is about 0.05% FSR.
