Hi Dale, Thanks for your inputs. As you have mentioned , ADS8588H has limitation due to limited bandwidth of internal analog filter. So,i have chosen ADS8528 according to my requirement. Pls refer to the datasheet for the same.From the page Nos (42) & (43)- it is clearly mentioned about interfacing opamp stage,filter with ADC input. But still,i need to confirm about the following since it is required to measure high frequency signals. Actually,the desired switching frequency of my converter is 25 kHz ,as a starting point. It may be increased to 50 kHz later.I understand from the datasheet - ADS8528 has 48Mhz bandwidth. Is there any other issues while using ADS8528 or ADS8568 for my application? Pls confirm. regards, Ramesh P
