CS53L30-CNZR

ADCs/DACs - Special Purpose Overview

The CS53L30-CNZR is a four-channel microphone analog-to-digital converter (ADC) manufactured by Cirrus Logic. It supports digital PDM and analog MEMS microphone inputs with independent bias voltages for each channel to enhance isolation. The device features integrated digital signal processing, including high-pass filters, noise gates, and volume control, to optimize voice capture. It outputs audio data via I2S or TDM interfaces at sampling rates up to 48 kHz. Designed for low power consumption, it consumes no more than 2.5 mW per channel, making it suitable for battery-operated consumer electronics requiring advanced voice processing capabilities.

• Multi-microphone arrays for beamforming applications

ADCs/DACs - Special Purpose Procurement Notes

The CS53L30-CNZR is listed as obsolete or discontinued by major distributors such as Mouser and DigiKey. Availability is restricted, and the part may not be in active production. Verification of current stock status and end-of-life notices from official manufacturer channels is required before procurement planning.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring four synchronized microphone inputs with minimal power overhead. Ensure the system architecture supports I2S or TDM output formats. Verify that the application benefits from the integrated DSP features for pre-processing, which reduces the computational load on the main processor.

ADCs/DACs - Special Purpose Part Context

The CS53L30 series is designed to enhance voice processing performance in consumer electronics. It enables advanced algorithms like beamforming and acoustic noise cancellation by providing high-quality, pre-processed audio data directly from the microphone array, improving speech recognition accuracy in noisy environments.

ADCs/DACs - Special Purpose Replacement Considerations

Check for updated revisions within the CS53L30 family, such as the CWZR package variant, if pin compatibility allows. Consult Cirrus Logic documentation for any recommended replacements due to the discontinued status of the CNZR package.
