Hello
I need to design a system to monitor current on approx 40 voltage rails. I will be using an Rsense + Current amplifier on each rail but I cannot send all outputs of Current amplifier directly to ADC in uController as I am not aware of any part with 40 channels. What I am thinking is to use Analog mux and send o/p of CSA to AMUX and then outputs of AMUX to ADC channles on uC.
Could any suggest any other way to do this? Also, can anyone suggest microcontroller and AMUX for this design? The voltage rails are between 0.5V to 5V and CSA should be able to measure current in range of couple of 100mA to 2A.
Thank you
Ann
