The following figure is the typical application circuit of this ic (btl mono) In the first stage amplifier, by change the ratio of r3/r2, you can change the first stage magnification. User can reset the source of sound by the actual situation, usually between 1-10 times. The power supply section uses the current and voltage integrated dynamic feedback circuit, this circuit has two advantages, for details, please see the related website of the tda7293/lm3886. The power supply section uses the three-terminal voltage regulator power supplier, r18/re18 is the current limit resistor (10 to 30 ohm), c9/ce9 is the 6800/35v large reservoir capacitors, power supply decoupling small capacitor is 0. 1u is the cbb capacitor of wima. The lm4766 has the warm tone, similar to the tube amp tone and the lm1875, but the power of lm4766 is larger than lm1875, I think it is the upgrade of lm1875, that's why it is the most popular ic of the music fans. Especially the friends who like the sound of lm1875.
