CS5361-KSZR

ADCs/DACs - Special Purpose Overview

The CS5361-KSZR is a 24-bit, multi-bit delta-sigma audio analog-to-digital converter (ADC) manufactured by Cirrus Logic. It features two differential analog inputs and supports system sampling rates up to 192 kHz per channel. The device integrates a 5th-order modulator with digital filtering and decimation, eliminating the need for external anti-alias filters. Key electrical specifications include a typical dynamic range of 114 dB and -105 dB THD+N. It operates on a single 5 V analog supply and logic supplies between 2.5 V and 5 V, consuming approximately 135 mW. The component is housed in a 24-pin SOIC package.

ADCs/DACs - Special Purpose Feature Summary

• Advanced Multi-bit Delta-Sigma Architecture: Uses a 5th-order modulator followed by digital filtering and decimation to remove the need for external anti-alias filters.
• High Performance: Delivers 114 dB dynamic range and -105 dB THD+N at 192 kHz sampling rates.
• Integrated Calibration: Includes an internal high-pass filter and DC offset calibration circuitry to prevent recording DC levels.
• Flexible Interface: Supports Left Justified and I²S serial audio formats with master or slave clocking modes.

ADCs/DACs - Special Purpose Applications

• A/V Receivers
• DVD-R and CD-R Recorders
• Digital Mixing Consoles
• Audio Effects Processors

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'KSZR' against official documentation, as standard datasheets list 'KSZ' (SOIC) and 'KZZ' (TSSOP). Confirm availability status, as some distributors indicate limited supply or end-of-life conditions for this family. Ensure the ordering information matches the required package type and temperature range (-10°C to 70°C) before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the CS5361-KSZR for applications requiring high-fidelity stereo audio conversion without external anti-alias filtering. Choose this part over the CS5381 if pin compatibility is needed but different feature sets are not required. Ensure the design accommodates the 24-pin SOIC footprint and provides separate decoupling for VA, VD, and VL supplies to maintain noise performance.

ADCs/DACs - Special Purpose Part Context

The CS5361 belongs to Cirrus Logic's line of 24-bit audio ADCs designed for professional and consumer audio systems. It is pin-compatible with the CS5381. The '-KSZ' suffix denotes the commercial temperature range (-10°C to 70°C) and the 24-pin SOIC package. The '-R' suffix typically indicates reel packaging, though verification with the manufacturer is recommended.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5361-KZZ is the TSSOP package equivalent within the same commercial temperature range. For automotive or extended temperature requirements (-40°C to 85°C), the CS5361-DZZ is the appropriate alternative. No direct functional substitutes are listed in the provided documentation.
