CS4362A-CQZR

ADCs/DACs - Special Purpose Overview

The CS4362A-CQZR is a 6-channel audio digital-to-analog converter (DAC) from Cirrus Logic, housed in a 48-pin LQFP package. It features 24-bit resolution and supports sample rates up to 192 kHz for PCM and Direct Stream Digital (DSD) formats. The device delivers a typical dynamic range of 114 dB with -100 dB THD+N. It operates on separate analog (+5 V), digital (+2.5 V), and logic (1.8 V to 5 V) supplies. Key specifications include selectable digital interpolation filters, 1 dB step volume control with soft ramp, and an integrated DSD processor with a 50 kHz filter.

ADCs/DACs - Special Purpose Feature Summary

• Advanced multi-bit delta-sigma architecture with mismatch shaping technology
• Integrated DSD processor supporting 50 kHz on-chip filtering without decimation
• Selectable fast and slow digital interpolation filters for PCM data
• 1 dB step size volume control with soft ramp functionality

ADCs/DACs - Special Purpose Applications

• SACD players
• A/V receivers
• Digital TV systems
• Mixing consoles and effects processors
• Automotive audio systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'CQZR' against the manufacturer's current documentation to confirm availability and specific packaging details. The datasheet indicates the commercial grade (-CQZ) operates within a temperature range of -40°C to +85°C. Confirm RoHS compliance status through official certification documents prior to procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high channel count and low clock-jitter sensitivity. Ensure power supply rails match the recommended operating conditions: VA at 5 V, VD at 2.5 V, and VLC/VLS between 1.8 V and 5 V. Verify that the host system supports the required serial interface formats (I²S, Left-Justified, etc.) and control port protocols (I²C or SPI).

ADCs/DACs - Special Purpose Part Context

The CS4362A belongs to Cirrus Logic's high-performance audio DAC family. The '-CQZ' designation identifies the commercial temperature grade variant in a Lead-free LQFP package. The 'R' suffix typically denotes tape and reel packaging, though specific packaging quantities should be verified in the latest ordering information section of the datasheet.

ADCs/DACs - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative Cirrus Logic models based on pin compatibility and electrical specifications if direct replacement is required.
