Stereo Headphone Amplifier

Stereo Headphone Amplifier circuit uses DC voltage source 9Volt. As the name suggests this headphone amplifier circuit has inpur stereo and output to power about 50mW at 32 Ohm load. The series of "Stereo Headphone Amplifier" It uses mini-amplifier IC NE5534. Because of this NE5534 IC didalamanya there are 2 pieces mini amplifier then simply use 1 piece of IC NE5534 to Stereo Amplifier aHeadphone this. Stereo Headphone Amplifier series has this capability and low distortion, low noise. Stereo Headphone Amplifier circuit has a strengthening of 3.5 with 3.6 Vpp at 32 Ohm load.
