Original question:

AMC1200: powering the low side only.

AMC3301: multiple AMC3301

Part Number: AMC3301

Hi Alex, if I use the amc3301 to measure currents in a shunt of a photovoltaic installation in the DC side, can I power multiple amc3301s with my raspberry pi without any problem? this would be using the circuit recommended in the data sheet.

    Hi Natalia,

    the low side supply current per AMC3301 will be up to 42mA.

    As example: If you have five AMC3301, the total power consumption of all five AMC3301 will be up to 210mA.

    Hi Natalia,

    As Kai mentioned, the power requirements would be your limitation.  The 42mA is MAX with a load on the high side LDO.  If you are doing a differential to single ended conversion, those amplifiers would need to be powered as well, so that would be additional power budget to consider.
