6. Detailed Description
Note1: When the unrecommended value is used, please examine it enough by system evaluation.
Note2: Since “AC-GND” pin is a common reference voltage for all input, this product needs to set the ratio of an
input apacitance (C1) and the AC-GND capacitance (C6) to 1 : 4.
Note3: Please use the low leak current apacitor for C1 and C6.
