CS48L10-CNZ

CS48L10-CNZ is a Cirrus Logic audio IC (model CS48L10). It’s a highly integrated stereo Class-D audio amplifier with onboard processing (DSP) designed for compact mobile and wearable devices. Key features typically include: digital audio input (I2S/PCM), I2C control interface for volume and settings, efficient amplification for small loudspeakers or headphones, and protections (pop-noise suppression, short-circuit/surge protection). The CNZ suffix usually denotes a specific packaging/ RoHS variant.
Common applications: smartphones, wearables, tablets, and small speaker systems where high efficiency and compact size are important.
Note: exact specs (supply voltage, outputs, THD, efficiency, pinout, and package details) vary by revision. For precise information, consult the official CS48L10 datasheet and the CNZ packaging documentation from Cirrus Logic. If you have a link or context (board, application, or supplier), I can tailor the intro further.

Here are the typical features of Cirrus Logic CS48L10-CNZ (audio SoC for headsets/earbuds):
- Integrated 24‑bit stereo DAC and ADC with flexible data paths
- DSP engine for audio processing (EQ, dynamics/companding, limiting, noise suppression, de‑essing)
- Digital microphone interface and/or support for multiple mics with biasing
- I2S/PCM digital audio interface for host processor connection
- Programmable routing, gain control, and mastering/volume control
- Microphone bias generator with programmable gain and protection
- Flexible clocking and wide sampling-rate support (up to high kHz ranges)
- Low-power operation with multiple power domains and sleep modes
- On‑chip calibration and test features
- Control via standard interfaces (I2C or SPI) for firmware programming
- Protection features (short‑circuit, over‑temp, undervoltage)
- Package variant CNZ (specific packaging details per supplier)
Note: exact I/O counts, mic counts, and DSP feature set can vary by revision and packaging; refer to the latest datasheet/SKU for precise specifications.
