PAM8908JER

PAM8908JER is a stereo headphone driver that 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 32ohm 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. Applications include smartphones/cellular phones, notebook computers, portable DVD players, personal digital assistants (PDAs), electronic dictionaries, digital still cameras, portable gaming.

• True cap free architecture, output biased at 0V (system ground)
• Excellent low frequency fidelity, support both fully differential and single-ended inputs
• Short-circuit and overtemperature protections
• Quiescent current is 4mA typ at EN = PVDD, no load
• Shutdown current is 0.1µA typ at EN = 0V, PVDD = 2.5V to 5.5V
• Power supply reject ratio is 75dB typ at input A C-GND, f + 1kHz, VPP = 200mV
• Noise output voltage is 10µVRMS typ (A-weighted)
• Total harmonic distortion plus noise is 0.03% typ at PO = 20mW, f = 1kHz
• Ambient temperature range from -40 to +85°C
• U-QFN3030-16 standard package
