Diodes Incorporated PAM8908
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 DCblocking capacitors, saving cost, board space, and component height. The PAM8908 delivers up to 60mW per channel into a 32Ω load and has low 0.03% THD+N.| Part No. | PAM8908 |

DESCRIPTION
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.
