Hi,
I have a btl signal ( both outputs are idle 1/2vcc, and signal is inverted between the two) that is created by an opamp.
Now I want to drive a fairly low resistor of about 100 ohms.
The requirements i have to meet are:
0-15V single supply
10Vpp max output signal (the opamp stage already creates that level)
I need to be safe - so the buffer stage should handle 2-3 Watts - to be on the safe side.
-> I need to buffer this, I guess I need to use a push/pull stage that can handle the input voltage, right? Does anyone have a schematics that meets the fucntionality?
