Dear Sir

We concern the power of ADAU176. As discussed in the datasheet, the ADAU1761 is a low power processor that supports stereo 48 kHz record and playback at 14 mW from a 1.8 V analog supply. However, when a 40-order digital filter program whose sampling rate is 48KHz, is running at the EVAL-ADAU1761Z under the condition that all unnecessary jumpers are unconnected, the power of ADAU1761 is more than 56mW. So I have a question that how do you test the power of ADAU1761?Could you provide a power test demo for me? Any recommendations about the power of ADAU 1761 can be provided
