Power on Timing
Applications must control the timing of the power on sequence carefully. Although AV
SS
and V
SS
are completely
isolated internally in the LC82151, AV
DD
and V
DD
are connected through the substrate. This means that there must be
no potential difference between AV
DD
and V
DD
. Also, the power supply voltage rise and fall times must be under 3 ms.
