Temperature”, for the package power dissipation of Ta from + 25 °C to + 85 °C.
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
WARNING: The use of negative voltage below −0.3 Volts on the GND pins (AGND, PGND1 to PGND7) may activate
parasitic transistors on the silicon, which can introduce abnormal operation.
Connecting the LX pin to either VDD pins (AVDD, PVDD1 to PVDD7) or GND pins (AGND, PGND1
to PGND7) directly may cause permanently damage to the device.
