• RE: ADS7851 - Anti-Aliasing filter design for SDR

  

  Luis Chioye

  Hello Filip, The ADS7851 is a SAR ADC, therefore the inputs of the device have to be driven with a low impedance source. In order to obtain the expected performance, the external driving circuit must be able to completely charge the ADC's internal sampling…
