TDA1308 is a new type of low voltage, low distortion, high speed, strong output operational amplifier IC. Its output stage used the MOS tube, can directly drive 32 Ω headphones. In TDA1308 circuit application instruction, shows a gain of 1 single-ended input amplifier circuit power supply and the negative side, but I try to change its periphery, take it into double side power supply is input amplifier circuit, the gain of 10 times. The advantage of this improvement is that cancelled the output capacitance, extends the low frequency limit, and received the required gain multiple. This circuit is shown in figure 1. NE5532N amplifier is very close to 10 times of circuitry, in addition to increasing composed of R3, C4 and R7, C13 two RC damping networks outside the rest are basically the same. The key in the amplifier
