Mr. Asaka,
The ADC14DC080 is a different speed grade of the ADC14DC105 and due to such close similarity of the products, an EVM is no longer available for the ADC14DC080, only the ADC14DC105. The EVM for the ADC14DC105 can be evaluated to validate all the features but will differ slightly in the performance.
To evaluate the performance of the ADC14DC080, an ADC14DC105LFEB eval board may be reworked to place an ADC14DC080 device.
Regards, Josh
