Title: maximum/nominal analog Input Common Mode Voltage (FMC104-2-2-4-1)
Post by: fmc104user on January 14, 2015, 05:52 AM

Dear 4DSP team,
 i have a question about the FMC104-2-2-4-1 board (diff. analog Inputs). What is the maximum & nominal Common Mode Voltage to GND of the differential analog input? I cannot find this Value in the User Manual (only the Value for the diff. Input Range 2Vpp).

Thanks for your Help!
Jonas

Dear Jonas,


The maximum common mode voltage is +3.3V, but in this case your signal amplitude must be 0V. The recommended common mode voltage is +1.65V (referred to ground).
