TLV320ADC6120: Input signal bandwidth

Hi,

I would like to know what is the real input signal bandwidth of this device.

There is only one reference at the top of page 32 (from its datasheet): "The device supports an input signal bandwidth up to 80 kHz, which allows the high-frequency non-audio signal to be recorded by using a 176.4-kHz (or higher) sample rate."

This a very important feature to be consider in the first page of the datasheet, and I can not find any other reference about it. If the sample rate goes up to 768kHz, why the input signal bandwidth is that low? is there any graph showing the attenuation of the input signal with higher frequencies? I just need more info about this.

Thanks in advance.

KR,

Ivan
