ADS1204: Power consumption and part temperature dependence on external clock option

Hi,

How would the power consumption of the ADS1204 increase if we moved from using a 20 MHz external clock (10 MHz sample rate) to a 32 MHz external clock (16 MHz sample rate)? How would this increased power consumption affect the temperature of the part for a given ambient temperature environment?

The performance degradation for external clocks > 20 MHz is acceptable for us.

Thank you,
Brian
