Use LM3876T to connect to BTL power amplifier

If you need to increase the power reserve of the amplifier, you can use two pieces of IC to connect to form a BTL circuit. Figure 2-58 shows a BTL power amplifier circuit using two
pieces of LM3876T to connect . If this circuit uses dual AC 27V power supply, it can output 120W power on an 8n load . In order to adapt to a variety of sound sources, NE5532 or LM833 can be used as a lOicU3 preamplifier. Tests show that when LM3876T is used as BTL output, the performance is quite good, while when LM 3875T is used as BTL output, the performance     is slightly worse.
