Part Number: ADC3444
Other Parts Discussed in Thread: ADC3442,

Dear Forum members.

Could you please comment on the following?

Is there a graph available detailing the power consumption on the analog and digital rails versus the sample rate?

For example if we were to use a ADC3444 clocked at the same rate as a ADC3442 (30MSPS)

Will they both use the same power or will the ADC3444 use a little bit more?

Thank you

Hey Ben,

I have forwarded your question to a device expert. He should be with you shortly.

Hi Ben,

These tables from the datasheet help to show how power is scaling across sample rate.

The power scaling should remain constant across the different speed grades, but datasheet performance is not guaranteed outside of specified conditions.

Best Regards,

Dan
