NAU85L40YGB

NAU85L40YGB is a Nuvoton NAU-series stereo audio CODEC intended for embedded/mobile audio front-ends. It integrates a stereo DAC and ADC, a headphone driver, mic bias circuitry, and a digital audio interface (I2S/PCM) to connect with an MCU/SoC. It supports standard audio sampling rates and word lengths via programmable registers, with built‑in power management for low quiescent current. Common applications include voice capture/playback, portable audio devices, IoT audio platforms, and USB audio bridges. The YGB suffix refers to packaging/lot code. For exact pinout, supply rails, register map, and reference designs, consult the NAU85L40YGB datasheet and Nuvoton evaluation resources. In short: a compact, integrated audio front-end that simplifies adding high‑quality audio to embedded systems.

Equivalents depend on its function and specs. What exactly is NAU85L40YGB (audio CODEC/ADC/DAC), and what are its key specs (channels, interface I2S/PCM, sampling rate, headphone/mic features, package)? With that, I can provide precise cross-references (TI, Cirrus Logic, Analog Devices, Maxim, etc.).
