CS5371-BSZ

ADCs/DACs - Special Purpose Overview

The CS5371-BSZ is a single-channel, high dynamic range, fourth-order delta-sigma modulator manufactured by Cirrus Logic. Designed for geophysical and sonar applications, it functions as an analog-to-digital front-end when paired with the CS5376 digital filter. The device features a clock jitter tolerant architecture and supports single or dual power supply configurations. It operates within a specified temperature range of -40°C to 85°C and is housed in a 24-pin SSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Fourth-order delta-sigma modulation architecture
• High dynamic range with 124 dB SNR at 411 Hz bandwidth
• Low total harmonic distortion (-118 dB typical)
• Low power consumption: 25 mW per channel (normal mode)

ADCs/DACs - Special Purpose Applications

• Geophysical data acquisition systems
• Sonar signal processing
• High-resolution A/D measurement systems

ADCs/DACs - Special Purpose Part Context

The CS5371-BSZ belongs to the CS5371 family of low-power, high-performance modulators. The 'BSZ' suffix indicates a specific package variant (SSOP) and lead-free compliance status within the Cirrus Logic product line. It is part of a system solution that includes the CS5376 digital filter to achieve complete high-resolution conversion capabilities.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5371A serves as a functional equivalent within the same family. Verification of pin compatibility and electrical parameter alignment with the CS5376 digital filter is required before substitution.
