LV5682P
Caution for usage
When allowablepower dissipation and power supply voltage exceed absolute maximum ratings or depends on usage
conditions, LV5682P may be destroyed before Thermal Shut Down circuit operates.
Particularly caution is required for CD output. CD output can output high current and power dissipation is high. Therefore,
when electric potential of VCC is high, a risk for IC destruction increases. The following diagram dhows Area of Safety
Operation (ASO) CD output under the TYP conditions. However, it omly shpws the case where CD output is used
independently. IC destruction may occur due to usage conditions in your system or manufacturing process of the IC.
Therefore, your system should be designed with margin for a practical usage.
