How can I calculate or find the input bandwidth of the AD7124-4 or -8? This is not mentioned on the datasheet. It does specify a maximum sampling rate of 19.2kSPS but since this is a delta-sigma ADC and uses oversampling it is not as simple as assuming that 19.2kSPS is the Nyquist rate and dividing by 2 to obtain input BW.

Hi,

AD7124 is designed for dc type applications thus we do not have a specified input bandwidth specs for this part. The measurable input bandwidth for AD7124 is very limited due to the sinc filter output, that's why it is intended for low bandwidth application typically close to dc. May I know what input frequency do you want to operate?

Thanks,
