CS5351K-KZZ

ADCs/DACs - Special Purpose Overview

The CS5351K-KZZ is a 24-bit, multi-bit delta-sigma analog-to-digital converter designed for digital audio systems. It integrates sampling, anti-alias filtering, and conversion, supporting system sample rates up to 192 kHz per channel. The device delivers a typical dynamic range of 108 dB and -98 dB THD+N at 1 kHz. It operates with single-ended analog inputs and supports logic levels between 2.5 V and 5 V. Power consumption is 135 mW under standard conditions. The component is housed in a 24-pin TSSOP package and functions within a commercial temperature range of -10°C to 70°C.

ADCs/DACs - Special Purpose Feature Summary

• Advanced multi-bit delta-sigma architecture with integrated digital decimation filters
• 108 dB dynamic range and -98 dB THD+N performance
• Supports output sample rates from 2 kHz to 204 kHz across three speed modes
• Built-in high-pass filter and DC offset calibration circuitry

ADCs/DACs - Special Purpose Applications

• Audio/Video receivers
• Digital mixing consoles
• Effects processors
• CD-R and DVD-R recording systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix KZZ confirms the commercial temperature grade (-10°C to 70°C) and lead-free status. Ensure the package type matches the required 24-pin TSSOP footprint. Confirm that the supply voltage requirements align with the specified VA, VD, and VL ranges before integration into the design.

ADCs/DACs - Special Purpose Selection Notes

Select this model when a 24-bit resolution and high dynamic range are required for stereo audio digitization. The CS5351K-KZZ is suitable for applications operating in moderate ambient temperatures. For automotive or wider industrial temperature ranges, consider the CS5351K-DZZ variant instead. Verify clocking requirements against Master or Slave mode configurations.

ADCs/DACs - Special Purpose Part Context

The CS5351K-KZZ belongs to the Cirrus Logic CS5351 family of audio ADCs. It is pin-compatible with the CS5361, facilitating potential upgrades or replacements in existing designs. The KZZ suffix specifically denotes the commercial temperature rating and lead-free construction, distinguishing it from the DZZ automotive-grade version.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5351K-DZZ serves as a direct pin-compatible replacement for higher temperature environments (-40°C to 85°C). Designers should verify thermal management requirements if substituting between the KZZ and DZZ variants.
