This is a design circuit for headphone buffer amplifier. This circuit is work based on 5532 IC. This is the figure of the circuit.
The key component is the 5532 Dual Op Amp. While ordinarily this part is chosen for it's low noise characteristics, it is also capable of delivering nearly 350mW of output power per side, more than enough to drive headphones. The circuit can operate from bipolar voltages from +/-5V to +/-18V and it is not absolutely necessary that the + and - supply voltages be the same magnitude. The superior supply voltage rejection of the IC allows operation with unregulated supplies.
