Current Measurement from C5515EVM+ADS1298

Hi Folks,

We are working on ECG Non-Bios code. As seen from below circuit, we removed R1 resistor and we want to measure current from CVDD.

We measured 32.55mA (1.295V)  which means 42.15mW. However; according to the datasheet of C5515, 0.22mW/MHz is typical value for 1.3V supply and our PLL frequency 100 MHz. So we should observe 22mW from CVDD (Shown in below figure)

  

What is the reason of this contradiction? 

Regards
