Current required from for each stacked ADC PI on a PI3

I have 3 ADC PI stacked on top of my PI 3B and with 24 ADXL335 connected to it to the ADC.
As fas as I know the ADXL335 takes 350µA each, do you know how much current I would expect the each ADC PI itself to get from the Raspebrry GPIO connector ?
Thanks for your help,
Stefano Falconetti.
Each of the MCP3424 ADC chips should use 180µA from the 5V GPIO pin in continuous conversion mode and 1µA during standby. The pull-up resistors on the ADC Pi draw a maximum of 1mA from the 5V GPIO pin and 660µA from the 3.3V GPIO pin so the total current draw for each ADC Pi should be approximately 2.02mA.
