Electrical Characteristics at Ta = –30 to +70°C, VDD = 4.5 to 5.5 V
Power on Timing
Applications must control the timing of the power on sequence carefully. Although AVSS and VSS are completely
isolated internally in the LC82151, AVDD and VDD are connected through the substrate. This means that there must be
no potential difference between AVDD and VDD. Also, the power supply voltage rise and fall times must be under 3 ms.
