개요
Description
NAU8315B31VG is a stereo audio CODEC from Nuvoton’s NAU831x family. It combines two ADCs and two DACs, plus analog front-end for line-in and microphone and a headphone driver. It provides a digital audio interface (I2S/PCM) to a host MCU/DSP and an I2C control port for register configuration. Typical features include 24-bit audio paths, support for standard PCM sample rates, digital volume control, mute/de-emphasis, and pop-noise suppression. Designed for low power in portable/embedded audio applications, it comes in a compact package (suffix B31VG indicates a specific variant). Use case: capture analog audio, process digitally, and drive headphones/line-out under MCU control. For exact specs (operating voltages, supported sample rates, register map, pinout), consult the official NAU8315B31VG datasheet from Nuvoton.
