conventional output stages. Using the BTL principle increases the output power. The maximum gain of the amplifier is fixed at 40.5 dB. The DC volume control stages have a logarithmic control characteristic. Therefore, the total gain can be controlled from +40.5 to −33 dB. If the DC volume control voltage falls below 0.4 V, the

https://www.maximintegrated.com/en/products/analog/audio/MAX9710.html
The MAX9710/MAX9711 are stereo/mono 3W bridge-tied load (BTL) audio power amplifiers. These devices are PC99/01 compliant, operate from a single 4.5V to 5.5V supply, and feature an industry-leading 100dB PSRR, which allows these devices to operate from noisy supplies without additional, costly power-supply conditioning.

What is BTL? | diyAudio

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.
TDA7491LP - 5W+5W dual BTL class-D audio amplifier ...
https://www.st.com/en/audio-ics/tda7491lp.html
The TDA7491LP is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors. Thanks to the high efficiency and exposed-pad-down (EPD) package no separate heatsink is required. Furthermore, the filterless operation allows a reduction in the external component count. The TDA7491LP is pin-to-pin compatible with ...

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.

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.
