CS3308K-CQZR

Audio Special Purpose Overview

The CS3308K-CQZR is an 8-channel digitally controlled analog volume control IC from Cirrus Logic. It provides independent volume adjustment for eight channels with a range of -96 dB to +22 dB in 1/4 dB steps. The device features low distortion (-112 dB THD+N) and high dynamic range (123 dB). It supports I²C and SPI serial interfaces for system integration, allowing control of up to 128 devices on a shared bus. Power supplies include ±5 V for analog sections and +3.3 V for digital logic. The component operates within a commercial temperature range of -10°C to +70°C.

Audio Special Purpose Feature Summary

• Wide Adjustable Volume Range from -96 dB to +22 dB in ¼ dB Steps
• Low Distortion & Noise: -112 dB THD+N and 123 dB Dynamic Range
• Noise-Free Level Transitions via Zero-Crossing Detection with Programmable Time-Out

Audio Special Purpose Applications

• High-end audio systems requiring multi-channel volume control
• Professional audio mixing consoles and processors
• Home theater and surround sound amplifiers

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix K-CQZR against manufacturer documentation to confirm package type and tape/reel specifications. Ensure supply chain sources provide valid traceability for Cirrus Logic components. Check for any product change notifications or end-of-life status updates prior to final procurement decisions.

Audio Special Purpose Selection Notes

Select this component when designing systems requiring precise, glitch-free analog volume attenuation and gain for multiple audio channels. Ensure the host controller supports either I²C or SPI protocols for configuration. Verify that the power supply rails can provide stable ±5 V for analog operation and +3.3 V for digital control signals to meet specified operating conditions.

Audio Special Purpose Part Context

The CS3308 belongs to Cirrus Logic's family of digitally controlled analog volume controls. It is distinct from audio codecs or DSPs, focusing specifically on analog signal path management. The K-CQZR designation indicates a specific packaging variant, typically Tape & Reel, suitable for automated surface mount assembly processes in manufacturing environments.
