CS4360-DZZ

ADCs/DACs - Special Purpose Overview

The CS4360-DZZ is a 24-bit, 192 kHz, 6-channel digital-to-analog converter (DAC) from Cirrus Logic. It integrates digital interpolation, fourth-order delta-sigma conversion, digital de-emphasis, volume control, channel mixing, and analog filtering. The device supports audio sample rates from 4 kHz to 200 kHz with a typical dynamic range of 102 dB and THD+N of -91 dB. It operates on a +3.3 V or +5 V analog supply and accepts logic levels between 1.8 V and 5.0 V. Packaged in a 28-pin TSSOP, it functions within an operating temperature range of -40 °C to +85 °C.

ADCs/DACs - Special Purpose Feature Summary

• Six independent channels with 24-bit resolution and 192 kHz sampling rate support
• Integrated digital volume control with 1-dB step size, soft ramp, and zero-crossing mute
• ATAPI mixing capability for multi-source audio routing
• Popguard® technology to suppress power-up/down clicks and pops

ADCs/DACs - Special Purpose Applications

• DVD players
• A/V receivers
• Set-top boxes
• Digital TVs and VCRs
• Mini-component systems
• Mixing consoles

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix DZZ indicates the industrial temperature grade (-40 °C to +85 °C). Confirm that the component is sourced as lead-free. Check current availability status as older revisions may be discontinued or subject to last-time buys.

ADCs/DACs - Special Purpose Selection Notes

Select the CS4360-DZZ when an industrial temperature range is required compared to the commercial KZZ variant. Ensure the system design accommodates the 28-pin TSSOP package dimensions. Verify that the host processor supports the required serial audio interface formats (I2S, Left Justified, Right Justified, DSP) and control port protocols (I²C or SPI).

ADCs/DACs - Special Purpose Part Context

The CS4360 belongs to Cirrus Logic's high-performance audio DAC family. The DZZ suffix specifically denotes the extended temperature range version, distinct from the standard commercial KZZ part. It shares architectural similarities with other multi-channel converters but is optimized for cost-sensitive home entertainment applications.

ADCs/DACs - Special Purpose Replacement Considerations

The CS4360-KZZ is the commercial temperature equivalent. For pin-compatible upgrades with enhanced features, consider the CS4361 or CS4364 series, though register maps and pinouts may differ.
