The PAM8901 stereo headphone driver is designed for portable equipment where board space is at a premium. The PAM8901 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 PAM8901 delivers up to 25mW per channel into a 16Ω 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 PAM8901 operates from a single supply from 2.5V t o 5.5V, has short-circuit and over temperature protection. Shutdown mode reduces supply current to less than 1μA.
