ADS58J64: what's the different between Nyquist 1 and Nyquist 2?

Hello,

This register helps to calibrate the ADC input. Since the ADC is interleaved, the ADC channels sample on separate chips. Inherently, there will be gain and offset differences between the different channels. If you know what your sample rate and analog input frequency will be, you can determine what Nyquist zone you will be operating in (1 or 2). By setting this register appropriately, you will be able to reduce noise and signal artifacts.

Regards,

Dan
