DIODES PAM8908JER

The PAM8908 stereo headphone driver is designed for portable equipment where board space is at a premium. The PAM8908 uses a unique, patent pending 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 PAM8908 delivers up to 60mW per channel into a 32Q load and has low 0.03% THD+N. A high power- supply rejection ratio (80dB at 1kHz) allows this device to operate from noisy digital supplies without an additional linear regulator. The PAM8908 operates from a single supply from 2.5V to 5.5V and has short- circuit and overtemperature protections. Shutdown mode reduces supply current to less than 1μA
