Quick question - maybe someone can help me understand the datasheet for the TDA7388.
I am a bit confused by the datasheet as it lists TWO "Max" ratings for the Vcc:
VS Operating supply voltage 18 V
VS (DC) DC supply voltage 28 V
This chip is typically meant for car audio applications it seems - but my application would be possibly running it from a 20 volt DeWalt battery (18v nominal, I know).
I especially do not understand what the difference between "VS Operating supply voltage" and "VS DC Supply voltage" is.
They further list the VS(pk) (peak) voltage as 50v for 50ms.
The application is an amplified portable speaker that has 4 channels (3-way xover) and this chip looks like it would fit the bill perfectly except for the possible voltage limitation.
