CS44600-CQZ

Audio Special Purpose Overview

The CS44600-CQZ is a fully integrated 6-channel audio processor from Cirrus Logic Inc., designed for high-performance digital speaker systems and A/V receivers. It combines analog-to-digital conversion, digital signal processing (DSP), and Class D amplifier control in a single package. The device features a 64-LQFP (10x10 mm) package with an exposed pad for thermal dissipation.

Audio Special Purpose Feature Summary

• Fully integrated 6-channel audio processor with built-in ADCs and DACs.
• Supports multi-channel audio systems with flexible input/output configurations.
• Integrated Class D amplifier controller with support for various modulation schemes.
• Low power consumption suitable for portable and automotive applications.

Audio Special Purpose Applications

• A/V receivers
• Digital speaker systems
• Automotive audio systems
• Home theater systems

Audio Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the unit is supplied in tube packaging. Ensure compliance with RoHS directives if required for specific regional regulations. Check for any product change notifications (PCN) related to manufacturing site consolidation or labeling updates prior to final design approval.

Audio Special Purpose Selection Notes

Select this component for designs requiring multi-channel digital amplification with minimal analog interference. Ensure the host processor supports either SPI or I²C control interfaces. Verify that the external power stage can handle the PWM outputs generated by the internal modulators. Consider the thermal requirements of the 64-LQFP package when designing the PCB layout for heat dissipation.

Audio Special Purpose Part Context

This part belongs to the Cirrus Logic CS44600 series of fully integrated audio processors. It is designed to interface directly with digital audio sources, processing signals through internal SRC and volume controls before driving Class D power stages. The device integrates general-purpose I/O pins and peak detection limiters for comprehensive system management.
