Hi, I have a differential bipolar signal with the range of (+10v to -10v) 20vp-p signal, This signal is connected to the input of pre-amplifier stage to convert the differential bipolar signal into single ended bipolar signal (+10v to -10v). The output of the preamplifier stage is connected to the PGA to varying the gain of the signal. My question is Shall I connect directly the output of PGA to ADS8519 ADC or I need to buffer the PGA output signal and then fed to the ADC ( ADS8519 ). I am attaching the block diagram for your reference, Please advice me. Regards, H.Mohamed
