Note) *6:All the values of analog characteristics were obtained by using our evaluation circumstance.
Depending upon parts and pattern layout to use, characteristics may be changed.
*7:AVDD and PVDD are different power supply.
*8:Measurements in VDDP=5V is the value in which snubber circuit (1Ω+330pF) is mounted.
