PAM8901 / PAM8908
25mW TRUE CAP FREE STEREO HEADPHONE AMPLIFIER
Description
The PAM8901 / PAM8908 stereo headphone driver is designed for
portable equipment where board space is at a premium. The
PAM8901 / 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 PAM8901 / PAM8908 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 / PAM8908 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.
