DATASHEET
SINGLE CHIP PC AUDIO SYSTEM
CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO+I2S
Description
The 92HD93 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.
Dual High Definition Audio and I2S Interfaces allow for
docking audio support with a single codec.
The integrated combo jack allows for dual-function
headphone and headset detection.
The integrated high-pass and band-pass filters allow for
Hardware EQ and speaker protection.
The high integration of the 92HD93 enables the smallest
PCB footprint with the lowest system audio BOM count and
cost.
The 92HD93 provides high quality HD Audio capability to
notebook and business desktop PC applications.
