CS5366-DQZ

ADCs/DACs - Special Purpose Overview

The CS5366-DQZ is a 6-channel audio analog-to-digital converter in a 48-pin LQFP package. It utilizes a 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. Key electrical specifications include a typical dynamic range of 114 dB and -105 dB THD+N. The device supports I²S, Left-Justified, and TDM interfaces with separate logic supplies (1.8 V to 5 V) for control and serial ports. It features an on-chip oscillator driver, low-latency digital filtering, and operates within an automotive temperature range of -40°C to +105°C.

ADCs/DACs - Special Purpose Feature Summary

• 6-channel differential analog input with 24-bit resolution
• Supports sample rates up to 216 kHz with selectable I²S, LJ, or TDM formats
• On-chip crystal oscillator driver and master/slave clock operation
• Individual channel mute, power-down, and overflow detection controls

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix DQZ confirms the automotive grade (-40°C to +105°C) and LQFP-48 package. Confirm current availability status as this component may be subject to end-of-life restrictions or limited stock from distributors. Ensure the source document matches the DS626F5 revision for accurate pinout and electrical characteristics.

ADCs/DACs - Special Purpose Selection Notes

Select the CS5366-DQZ when six synchronized audio channels are required with high dynamic range and low distortion. The automotive grade variant is necessary for applications operating between -40°C and +105°C. Consider the footprint compatibility with the 8-channel CS5368 if future scalability is needed. Verify that the system clocking requirements align with the on-chip oscillator or external master clock capabilities.

ADCs/DACs - Special Purpose Part Context

The CS5366 belongs to Cirrus Logic's professional audio ADC family. The -DQZ suffix denotes the automotive temperature range and LQFP-48 package. It serves as a precursor or companion to the 8-channel CS5368, sharing similar architectural features but offering a smaller channel count for cost-sensitive or space-constrained multi-channel designs.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5366-CQZ is the commercial grade equivalent with a -40°C to +85°C operating range. The CS5368 provides 8 channels with a compatible footprint.
