BTL power amplifier composed of single power amplifier

The 13TL power amplifier with discrete components has a complex circuit structure. The circuit structure of the BTL power amplifier composed of integrated power amplifier circuits
is very simple, and its performance is equivalent to that of discrete components . Some integrated power amplifiers make two sets of power amplifiers on one integrated circuit, called
bi-amplification. It is easiest to form a BT'L power amplifier circuit. Figure t-43 shows the BTL power amplifier circuit
    composed of TDA2030A single power amplifier . This circuit can output a maximum power of 34W under the dual power supply voltage of ±16V. When using a single power amplifier , the maximum output power is 14W.
