Description
Features
The 92HD88 single-chip audio system is a low power
optimized, high fidelity, 4-channel audio codec with
integrated mono speaker amplifier, capless headphone
amplifier, and low drop out voltage regulator.
The high integration of the 92HD88 enables the smallest
PCB footprint with the lowest system BOM count and cost.
The 92HD88 provides high quality HD Audio capability to
notebook and business desktop PC applications.
