CS43131-CNZ

Digital To Analog Converters Overview

The CS43131-CNZ is a high-performance stereo audio digital-to-analog converter (DAC) manufactured by Cirrus Logic. It features a 32-bit resolution and utilizes delta-sigma architecture to deliver superior audio fidelity. The device integrates two DAC channels with an output dynamic range of 130 dB and a total harmonic distortion plus noise (THD+N) of -115 dB. It operates within a supply voltage range of 1.66 V to 1.94 V and supports I2C interface control. The component is housed in a 40-pin QFN package measuring 5x5 mm, suitable for surface mount technology applications across a temperature range of -10°C to +70°C.

Digital To Analog Converters Feature Summary

• Integrates dual high-resolution delta-sigma DACs for stereo audio processing
• Includes integrated headphone driver with impedance detection capability
• Supports standard I2C serial interface for configuration and control

Digital To Analog Converters Applications

• High-fidelity portable audio devices requiring independent DAC solutions
• Smartphones and tablets utilizing USB-C or Lightning audio adapters
• Premium consumer electronics demanding low-noise analog output stages

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CNZ' to confirm the tray packaging format distinct from the 'R' variant which indicates tape and reel. Confirm RoHS compliance status and lead times directly with authorized distributors as these parameters fluctuate. Ensure the ordering part number matches the exact package type required for the PCB footprint design.

Digital To Analog Converters Selection Notes

Select this component when a dedicated high-performance DAC with integrated headphone amplification is required. Compare against the CS43131-CWZR if a smaller WLCSP package is preferred over the QFN-40 form factor. Ensure the system design accommodates the specific 1.66V to 1.94V supply voltage constraints and thermal requirements of the QFN-40 package.

Digital To Analog Converters Part Context

This part belongs to the Cirrus Logic MasterHIFI series, designed for premium audio applications. It serves as a standalone solution often found in high-end mobile devices and dongles where space efficiency and audio quality are critical. It complements other Cirrus Logic codecs by providing discrete high-performance conversion capabilities.

Digital To Analog Converters Replacement Considerations

The CS43131-CWZR is a pin-compatible alternative offering the same functionality in a WLCSP-42 package. Verify mechanical fit and soldering process compatibility before substituting the QFN package with the wafer-level chip scale package.
