ADS4449: Amplitude input

May

Part Number: ADS4449


Hi Team,

Good day.

Customer want to calculate the amplitude input signal of device from the 14bit output. 

According to them, they know that the full scale input of ADS4449 IS 2Vpp ,and the unit of input is dBFS but they want to know how they can get the specific Amplitude of the input?

Is there a way to calculate this?

Thank you and looking forward for your kind response.

Regards,

Maynard

    Hi Maynard,

    I'm not sure I fully understand the question. Are they wanting to know how to convert from dBFS to an amplitude?

    and

    Where " % VFS" is the input voltage relative to the full scale input voltage in decimal format.
