Headphone Amplifier project featuring the NE5532 OP-Amp and a powerful Class AB output stage
by bocaletto-luca
This document describes the design, simulation, PCB layout, and testing procedures for a two-stage wideband RF gain block amplifier covering 0.1 to 50 MHz. The amplifier delivers 24 dB gain, a noise figure below 3 dB, and unconditional stability while operating from a single 5 V supply. All component values, footprints, and layout guidelines are...
