CS4384-CQZ

ADCs/DACs - Special Purpose Overview

The CS4384-CQZ is an 8-channel digital-to-analog converter (DAC) from Cirrus Logic, designed for high-fidelity audio applications. It features a multi-bit delta-sigma architecture with 24-bit resolution and supports sample rates up to 192 kHz. The device provides a typical dynamic range of 103 dB and -88 dB THD+N. It includes a proprietary DSD processor for Direct Stream Digital input without decimation, selectable digital filters, and half-dB step volume control with soft ramp. Power supplies include +5 V analog, +2.5 V digital, and 1.8–5 V logic for control and serial ports. It is housed in a 48-pin LQFP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix '-CQZ' corresponds to the commercial temperature grade (-40°C to +85°C) and 48-pin LQFP package as defined in the datasheet. Confirm that the required power supply voltages (+5V analog, +2.5V digital, 1.8-5V logic) are compatible with the target system design before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the CS4384-CQZ for systems requiring 8-channel single-ended outputs with DSD support. Ensure the host interface supports TDM or standard PCM formats. Verify that the application can accommodate the separate analog (+5V), digital (+2.5V), and logic (1.8-5V) power domains specified in the recommended operating conditions.

ADCs/DACs - Special Purpose Part Context

The CS4384 is part of Cirrus Logic's high-performance audio DAC family. It utilizes advanced multi-bit delta-sigma modulation with mismatch shaping technology to reduce distortion. The device integrates digital de-emphasis, volume control, and mute functions, reducing external component count compared to earlier generations.
