19-2386; Rev 2; 10/02 80mW, DirectDrive Stereo Headphone Driver with Shutdown General Description The MAX4410 stereo headphone driver is designed for portable equipment where board space is at a premium. The MAX4410 uses a unique, patented, DirectDrive architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height. The MAX4410 delivers up to 80mW per channel into a 16Ω load and has low 0.003% THD + N. A high powersupply rejection ratio (90dB at 1kHz) allows this device to operate from noisy digital supplies without an additional linear regulator. The MAX4410 includes ±8kV ESD protection on the headphone outputs.
