概述

Description

CS53L21-CNZ is a Cirrus Logic stereo audio CODEC IC. It integrates analog-to-digital and digital-to-analog converters, often with a built-in headphone/speaker driver, and a programmable digital audio interface (I2S/PCM). It’s designed for portable/embedded devices that need low-power, compact audio processing, such as smartphones, tablets, wearables, headsets, and other consumer-audio applications.
The “-CNZ” suffix denotes a specific package/variant from Cirrus Logic (same core, different pinout or packaging details). Exact electrical specs (supply, sampling rates, SNR/THD, input/output channels, microphone bias, interface formats, package size) are found in the CS53L21-CNZ datasheet on Cirrus Logic’s website or distributors.
If you share your target voltages, interfaces, and footprint, I can help verify suitability and map pinout to your design.

Features

Here are the typical features of CS53L21-CNZ (Cirrus Logic stereo CODEC):
- 24-bit stereo DAC and 24-bit stereo ADC
- I2S/PCM digital audio interface (serial audio data formats)
- Integrated headphone driver and line-out
- Analog input paths and microphone bias for MEMS/electret mics
- On-chip DSP features: programmable gain, mute, soft ramp, DC offset removal, and pop/noise suppression
- Low-power operation with various power/standby modes
- Supports common sampling rates up to around 48 kHz
- Compact CNZ packaging suitable for mobile/embedded designs
Note: Refer to the official CS53L21-CNZ datasheet for exact electrical specs, voltage ranges, current consumption, and supported formats.
