Hi team,

Both ADC08D500 and ADC08D502 different are D500 can interleave to 1GBPS per channel but D502 only 500MBPS.

Besides both device performance are same? thanks!

Hi Jimmy,

The key difference is ADC08D502 has DES mode disabled.

This enabled the device to be below the export restriction threshold which at that time was 1GSPS for 8-bit devices.

Removing the feature limited the sample rate to 500 MSPS.

Regards,

Rob

Hi Jimmy,

Correct, there is no DES mode. This the difference. The D500 part has the DES mode option.
