I have a question from a customer about effective noise bandwidth of AD7175-8 and AD7176-2.
In the datasheet for LTC2444, EFFECTIVE NOISE BW is presented in table-8.
The customer need to know the same parameter to estimete SNR of his system.
Could you please present the effective noise band width of AD7175-8 and AD7176-2 ?
Apologies, this was missed. May I know what is your application and why do you need this type of information? The AD717x is designed for dc type of application. May I know what input frequency will you intend to operate or what sensor are you going to use? Since the digital filter filters out the wideband noise from the input signal, I think the wideband noise is not much of the concern if you intend to operate at very low frequency. If you take a look at the example on the LT part, from the total noise, the wideband noise is much smaller than the ADC noise so the ADC noise dominate the total noise. But if you would like to see the filter response of the AD7175/AD7176 we have EVAL+ Software and Virtual Eval Tool which lets you play with various ADC's performance including the frequency response. You can try and visit this to help you evaluate and understand the ADC performance.
