SINGLE CHIP PC AUDIO SYSTEM

CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO+I2S

Description

The 92HD90 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 92HD90 enables the smallest

PCB footprint with the lowest system audio BOM count and

cost.

The 92HD90 provides high quality HD Audio capability to

notebook and business desktop PC applications.
