Hello,

In order to take advantage of the full dynamic range of the ADAU1328 ADC, you must drive it differentially with a maximum input level of 1.9 V RMS; this voltage level will reach 0 dBFS.

Best regards,

Coleman

Hi Coleman,

Thankyou for the information .

Could you please let me as to why the Full-scale input Voltage (Differential) rating is present on preliminary data sheet Rev .prB and not on the present data sheet .

Thanking you

With best regards and wishes

Hi Srivatsa,

A pr version of a datasheet is meant only as a preliminary document; as an employee at Fuji, you must have been in contact with our group before the product was released, and before I started working here. I do not have an explanation about the lack of a Full Scale Input Voltage specification in the released datasheet. Please use the AD1938 datasheet as a reference for the ADAU1328; the only difference is the temperature rating.

Best regards,

Coleman
