CS4226-BQZ

Audio Special Purpose Overview

The CS4226-BQZ is a single-chip audio codec manufactured by Cirrus Logic Inc. It integrates stereo analog-to-digital converters (ADC) and six digital-to-analog converters (DAC) utilizing Delta-Sigma conversion techniques. The device operates within a voltage supply range of 4.75V to 5.25V and supports I2C and SPI interfaces for control. Designed for automotive grade applications, it functions reliably between -40°C and +85°C. Key features include independent volume control for each D/A channel.

Audio Special Purpose Feature Summary

• Integrates stereo analog-to-digital converters and six digital-to-analog converters
• Features up to 96 dB of dynamic range
• Provides independent volume control for all six D/A channels
• Supports both I²C and SPI communication protocols

Audio Special Purpose Applications

• Home theater systems
• Car audio systems

Audio Special Purpose Procurement Notes

Verify the specific suffix BQZ confirms the -40°C to +85°C automotive temperature range and 44-LQFP package. Confirm RoHS compliance status through official manufacturer documentation or certificates prior to procurement. Check for obsolescence notices as this component series may have end-of-life announcements.

Audio Special Purpose Selection Notes

Select the CS4226-BQZ when a multi-channel surround sound solution with integrated ADCs and high-performance DACs is required. Ensure the system design accommodates the 5V supply requirement and utilizes I2C or SPI for configuration. Verify that the 44-pin LQFP package fits the PCB layout constraints and thermal requirements for the intended operating environment.
