Headphone Amplifier - NE5532

NE5532 is a low-distortion, low-noise Hi-Fi OP-Amp.
NE5532 is able to drive low-impedance Loads to a full
Voltage swing while maintaining low distortion.
NE5532 output is short-circuit proof.

This Circuit was implemented with a single 5532 Chip forming a pair of inverting Amplifiers, having an AC Gain of about 3.5 and capable of delivering up to 3.6V Peak-to-peak into a 32Ω Load (corresponding to 50mW RMS) at less than 0.025% total harmonic distortion (THD).
