Power amplifier The power amplifier is a Bridge Tied Load (BTL) amplifier with a complementary PNP-NPN output stage. The voltage loss on the positive supply line is the saturation voltage of a PNP power transistor, on the negative side the saturation voltage of an NPN power transistor. The total voltage loss is <1 V and with a 5 V

Noisy BTL Audio Amplifier Circuit. Ask Question Asked 4 years, 6 months ago. Active 2 years ago. Viewed 925 times 1 \$\begingroup\$ I designed and breadboarded a simple audio amplifier circuit and when I play audio through the speaker, it is pretty noisy and very quiet. The +5V is being supplied from a USB port.
What is BTL? | diyAudio
https://www.diyaudio.com/community/threads/what-is-btl.242674/
BTL = Bridge Tied Load. It means the the amplifier has two outputs per speaker - one inverting and one non-inverting, the speaker being connected between them. This gives double the voltage swing across the speaker and therefore 4 times the power for a given power supply voltage - assuming the amplifier can supply enough current.

As an example, for a BTL-coupled amplifier that can handle a single supply voltage of 36V, the rms value of the sine half-wave that can be generated by the amplifier is 36Veff/1.5=24Vrms. With the rms voltage of the sine wave signal, the power in a load can be calculated using the expression Vrms*Vrms/Rload.
