DATASHEET
SINGLE CHIP PC AUDIO SYSTEM
CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO
92HD99
Features
•
4 Channels (2 stereo DACs and 2 stereo ADCs)
with 24-bit resolution
•
Supports full-duplex stereo audio and simultaneous
VoIP
Description
The 92HD99 single-chip audio system is a low power
optimized, high fidelity, 4-channel audio codec with stereo
integrated speaker amplifier, capless headphone amplifier,
and low drop out voltage regulator.
The high integration of the 92HD99 enables the smallest
PCB footprint with the lowest system BOM count and cost.
92HD99 provides high quality HD Audio capability to
notebook and business desktop PC applications.
