92HD81 datasheet, circuit
SINGLE CHIP PC AUDIO SYSTEM
CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO
Description
The 92HD81 single-chip audio system is a low power
optimized, high fidelity, 4-channel audio codec with
integrated speaker amplifier, capless headphone amplifier,
and low drop out voltage regulator.
The high integration of the 92HD81 enables the smallest
PCB footprint with the lowest system BOM count and cost.
The integrated high-pass filter allows for speaker
protection.
The 92HD81 provides high quality HD Audio capability to
notebook and business desktop PC applications.
