Analog Input Configuration

By default, the analog input for the ADC354xEVM is configured for an AC-coupled, balun signal chain. For best spurious performance, the input frequency should be above 2 MHz.

For DC-coupled inputs, and those below 2 MHz, the FDA input path should be used. This can be done by making the following modifications to the EVM:

  • DNI: R116, R118, R119, R120, C81, C84
  • Install: C79 (use 0-Ω resistor for DC coupled input), R115, R122, and R134
  • C88 and C92 may be bypassed (short with 0-Ω resistor) to create DC ground.

Once these modifications are performed, the analog input must be connected to J10.
