SINGLE CHIP PC AUDIO SYSTEM

CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO

92HD81

•

Full ECR15B low power support

•

Audio inactivity transitions codec from D0 to D3 low

power mode

Resume from D3 to D0 with audio activity in < 10 msec

D3 to D0 transition with < -65dB pop/click

Port presence detect in D3 with or without bit clock

Optional analog PC beep in D3

Additional vendor specific modes for even lower power

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.
