CS4362A-DQZ

ADCs/DACs - Special Purpose Overview

The CS4362A-DQZ is an automotive-grade, 6-channel digital-to-analog converter (DAC) from Cirrus Logic. It features a 24-bit resolution and supports sample rates up to 192 kHz for PCM and Direct Stream Digital (DSD) formats. The device utilizes an advanced multi-bit delta-sigma architecture with mismatch shaping technology to eliminate distortion. Key electrical specifications include a typical dynamic range of 114 dB A-weighted and -100 dB THD+N at full scale. It operates with a +5 V analog supply, a +2.5 V digital supply, and separate 1.8 V to 5 V logic supplies for control and serial ports.

ADCs/DACs - Special Purpose Feature Summary

• Six-channel differential output with 114 dB dynamic range and -100 dB THD+N
• Supports PCM data up to 216 kHz and DSD audio with on-chip 50 kHz filtering
• Integrated 1 dB step size volume control with soft ramp functionality
• Selectable fast and slow digital interpolation filters with digital de-emphasis

ADCs/DACs - Special Purpose Applications

• Automotive audio systems
• SACD players
• A/V receivers
• Digital mixing consoles
• Sound cards

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DQZ' confirms the Automotive grade (-40°C to +105°C) operating temperature range. Confirm power supply requirements match the datasheet: VA at 5 V, VD at 2.5 V, and VLC/VLS at 1.8 V to 5 V. Ensure the design accommodates the 48-pin LQFP package dimensions and thermal characteristics specified in the official documentation.

ADCs/DACs - Special Purpose Selection Notes

Select the CS4362A-DQZ for applications requiring six independent channels with high-fidelity audio performance in automotive environments. The device supports both I²C and SPI control interfaces. Designers must account for the separate analog (5 V) and digital (2.5 V) supply rails. The DSD mode allows direct processing without intermediate decimation, simplifying system architecture for SACD playback.

ADCs/DACs - Special Purpose Part Context

The CS4362A is part of Cirrus Logic's high-performance DAC family. The '-DQZ' suffix denotes the Automotive grade variant housed in a 48-LQFP (7x7 mm) package. This distinguishes it from the Commercial grade '-CQZ' variant, which shares identical electrical specifications but operates within a narrower temperature range of -40°C to +85°C.

ADCs/DACs - Special Purpose Replacement Considerations

The CS4362A-CQZ is the commercial-grade equivalent with identical pinout and specifications, differing only in the guaranteed operating temperature range. No other direct functional substitutes are documented in the provided source material.
