92HD87
Overview
The 92HD87 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 92HD87 and the 40QFN package enables the smallest PCB footprint with the lowest system BOM count and cost.
