PCM4202 full scale level

[yo8tot]

What is the full scale input voltage of PCM4202 ADC? Acording to datasheet this is 6V. However it say also this:

"The analog input
should not swing below analog ground or above the VCC
power supply by more than 300mV."

and then this:

"The full-scale input of the PCM4202 is 6.0VPP
differential, while it is 5.0VPP for the PCM1804. This
is a result of the PCM4202 having an internal +3.0V
voltage reference, and the PCM1804 having an
internal +2.5V voltage reference. "

But the supply voltage is 5V, also in application example. (6V is max. absolute value).

Re-read the data sheets, try to understand the definition of Vpp differential. 5 or 6 Vpp differential is well inside the common mode range of a 5V device. It involves a maximum differential input of 3 V.

So you mean a 6Vpp signal fit inside a 0-5V interval?

 

[FvM]

Did you read? 6 Vpp differential means both inputs are swinging between 1 and 4 V.

Now I understand, thanks!
