voltage range can be extended if lower output swing is used or distortion
degradation is allowed, and increased bias current into pin is acceptable. For more information, see Figure 18 and Figure 34.
(3) Tested using JEDEC High-K test PCB. Thermal management of the final printed circuit board (PCB) should keep the junction
temperature below +125°C for long term reliability.
