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 92HD81 provides

high quality HD Audio capability to notebook and business

desktop PC applications.
