Présentation

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.

Features

CS53L21-CNZ is a Cirrus Logic stereo audio CODEC with an integrated headphone driver. Key features include:
- 2-channel stereo ADC/DAC with integrated headphone amplifier
- 24-bit audio path; supports mic bias, mic input, and line-in
- Analog outputs: headphone and line-out
- Digital interface: I2S (and PCM) with control via I2C
- Programmable gain, digital volume control, and mute
- Power management with multiple low-power modes and shutdown
- Wide supply range suitable for mobile platforms; compact CNZ package
Typical applications: mobile devices, headsets, small speaker systems. For exact electrical specs, sampling rates, and control registers, refer to the official datasheet for CS53L21-CNZ.

Pinout

Pin count: 20 pins.
Function: Cirrus CS53L21-CNZ is a stereo audio CODEC (ADC/DAC) with an I2S/PCM digital audio interface, including analog inputs (e.g., mic/line) and audio outputs (headphone/speaker).

Manufacturer

Manufacturer: Cirrus Logic, Inc.
Cirrus Logic is an American fabless semiconductor company that designs and markets audio, voice, and other mixed-signal integrated circuits for consumer electronics.

Application

I’m not certain what CS53L21-CNZ precisely is without the datasheet. If it’s a low‑power sensing/processing IC, typical application areas include:
- Mobile devices and wearables (motion/environment sensing, health tracking)
- IoT edge sensors and smart home devices
- Consumer electronics (audio capture, voice/proximity sensing)
- Industrial automation and robotics (sensor fusion, monitoring)
- Automotive (sensors for safety, cabin/environment sensing)
Note: exact applications depend on the device’s capabilities; please consult the manufacturer’s datasheet for precise use cases.

Package

CS53L21-CNZ is packaged in a QFN (Quad Flat No-Lead) package.
