CS5351K-KZZR

ADCs/DACs - Special Purpose Overview

The CS5351K-KZZR is a commercial-grade, 24-bit stereo audio analog-to-digital converter from Cirrus Logic. It utilizes an advanced multi-bit delta-sigma architecture to achieve 108 dB dynamic range and -98 dB THD+N at sampling rates up to 192 kHz per channel. The device integrates sampling, anti-alias filtering, and digital decimation, eliminating the need for external anti-alias filters. It operates with analog supply (VA) between 4.75 V and 5.25 V, logic supply (VL) between 2.37 V and 5.25 V, and digital supply (VD) between 3.1 V and 5.25 V. The component is housed in a 24-pin TSSOP package and supports serial audio interfaces including I2S and Left-Justified formats.

ADCs/DACs - Special Purpose Procurement Notes

Verify that the specific ordering suffix KZZR corresponds to the lead-free, reel-packaged variant intended for surface-mount assembly. Confirm the commercial temperature grade (-10°C to +70°C) aligns with system requirements, as automotive variants (DZZ) offer extended ranges. Ensure power supply decoupling capacitors are placed close to the device pins to maintain specified noise rejection ratios.

ADCs/DACs - Special Purpose Selection Notes

Select this component when pin compatibility with the CS5361 is required but the specific performance metrics of the CS5351 are sufficient. Choose based on the required operating temperature range; the KZZ suffix denotes commercial grade, while DZZ denotes automotive grade. Verify that the system clocking architecture supports either Master or Slave mode configurations as defined by the M/S pin state.

ADCs/DACs - Special Purpose Part Context

The CS5351 belongs to the Cirrus Logic CS53xx series of high-performance audio ADCs. It shares the same 24-pin TSSOP footprint and pinout as the CS5361, facilitating direct board-level upgrades or replacements where minor differences in specifications do not impact system design. The KZZR designation indicates the commercial temperature range and tape-and-reel packaging format.

ADCs/DACs - Special Purpose Replacement Considerations

The datasheet explicitly states the CS5351 is pin compatible with the CS5361. Designers should verify that the target application can accommodate any differences in absolute maximum ratings or specific electrical characteristics between the two models before substitution.
