Hello,
The datasheet specifies ADS5463-SP power dissipation is 2.45W(max) at Vin=full scale, fin=300MHz and Fs=500MSPS. My customer plans to use ADS5463-SP at 100MSPS. How much would the power dissipation be?
Best regards,
K.Hirano

Hi Hirano-san,
Using our ADS5463EVM-CVAL, I applied a 100 MSPS clock and 301 MHz input driven to -0.95 dBFs. The power supplies current were as follows:
5V AVDD: 290.6 mA
3.3V AVDD:133.2 mA
3.3V DVDD: 80.4 mA
This is roughly 2.158 W

Drew,
Thank you for your response.
I am sorry, here is one more measurement request from my customer.
Could you measure the power dissipation at the following condition, please?
100 MSPS clock and 10.23MHz input driven to +0.3dBm
best regards,
K.Hirano
Hi Hirano-san,
Here are the results from the above condition:
5V AVDD: 291 mA
3.3V AVDD:133.3 mA
3.3V DVDD: 80.4 mA
This is roughly 2.16 W
Best regards,
Drew
