Dear Sir,
we would like to consult about the test phenomenon of power consumption and surface temperature of ADC chip adc12dj3200, which is used in the following block diagram. Our measured power consumption is 3.25W, specifically 1.9-V analog supply current is 1.001A, 1.1-V analog supply current is 0.596A, 1.1-V digital supply current is 0.683A. Is this power consumption normal(dual channel, 8lane)?
In addition, in the absence of heat dissipation measures, we measured that the chip surface temperature rose to 75 ° C within 1.5 minutes through the infrared thermometer. Is this temperature rise normal?
