Overview
Description
CS53L21-CNZ is a model number for the CS53L21 family audio CODEC IC (the -CNZ suffix denotes a specific package/variant). It typically provides stereo analog-to-digital and digital-to-analog conversion, a built‑in headphone driver, mic bias/input, and a digital interface (I2S/PCM) to a host processor. Designed for low power in mobile/embedded devices, it’s used in items like phones, tablets, wearables, and IoT audio products. For exact specs—voltage ranges, supported sample rates, bit depth, pinout, and package details—refer to the official CS53L21 datasheet and the -CNZ packaging documentation.
