CS5366-CQZ

ADCs/DACs - Special Purpose Overview

The CS5366-CQZ is a 6-channel analog-to-digital converter (ADC) from Cirrus Logic, designed for digital audio systems. It utilizes an advanced multi-bit delta-sigma architecture to perform sampling, anti-alias filtering, and conversion, generating 24-bit serial data at sample rates up to 216 kHz per channel. The device features a low-latency digital filter, eliminating the need for external anti-aliasing components. It supports selectable audio interface formats including Left-Justified, I²S, and high-speed TDM. The CS5366-CQZ operates within a commercial temperature range of -40°C to +85°C and is housed in a 48-pin LQFP package.

ADCs/DACs - Special Purpose Feature Summary

• Six differential analog inputs with 24-bit resolution and 114 dB dynamic range.
• Supports audio sample rates up to 216 kHz with -105 dB THD+N.
• Features on-chip oscillator driver and separate logic supplies (1.8 V to 5 V) for control and serial ports.
• Includes individual channel mute, power-down, and overflow detection capabilities.

ADCs/DACs - Special Purpose Applications

• A/V receivers
• Digital mixing consoles
• Multi-channel recorders
• Outboard converters
• Automotive audio systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix 'CQZ' confirms the Commercial grade (-40°C to +85°C) and LQFP-48 package. Confirm RoHS compliance status via current manufacturer documentation. Ensure supply chain availability as component lifecycles may change. Cross-reference pinout compatibility if replacing older variants.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring six simultaneous audio channels with high dynamic range. Choose the CS5366-DQZ variant if automotive grade operation up to +105°C is required. Ensure system design accommodates the separate VA, VD, VLS, and VLC power domains. Verify that the host processor supports the desired serial interface format (I²S, LJ, or TDM).

ADCs/DACs - Special Purpose Part Context

The CS5366-CQZ belongs to the CS5366 family of 6-channel audio ADCs. It shares footprint compatibility with the 8-channel CS5368. The 'CQZ' designation specifically identifies the commercial temperature range version in the LQFP package, distinguishing it from the automotive 'DQZ' variant.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5366-DQZ serves as the direct automotive-grade replacement, offering extended temperature support up to +105°C while maintaining identical pinouts and functionality. No other functional substitutes are documented in the provided source material.
