Hi Binbin,

 

Nice to know you here. Could you give me your application and why you need a convert time less than 500ns.  Many ADC has different timing. For example, you can refer to ADS8688. The timing of this chip is not the same with the timing you attached. 

So, let us know your application and your requirement behind this  spec.
