At analog input pins of LTC2381-16 is there any DC reference should be given?
The common mode voltage (Vin+ + Vin-)/2 at the analog inputs must remain fixed at Vref/2 +/-50mV.
for zero level should i get 32767 sample?
With the inputs shorted together and tied to Vref/2, the ideal output code is all zeros. Figure 2 of the LTC2381-16 datasheet shows the transfer function.
