Hi team,
in the evaluation board of the ADC12DL3200, the analog inputs INA +- and INB +- are inverted.
The figure shows the schematic: the output 1 of the balun 1 (pin 3) is connected to the INA+ (pin A4) and the output 1 of the balun 2 (pin 3) is connected to the INB- (pin T5).
In this way the two input signals are 180° out of phase. Is it correct?
In the attached document there is an alternative input configuration with a different balun transformer?
Is this configuration correct?
Thank you in advance.
Best Regards.
