CS5371-BS

ADCs/DACs - Special Purpose Overview

The CS5371-BS 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 requiring an external digital filter, such as the CS5376. The device features a clock jitter-tolerant architecture with a 5 V peak-to-peak input voltage range. It offers a signal-to-noise ratio of 124 dB at a 411 Hz bandwidth and -118 dB typical total harmonic distortion. Power consumption is rated at 25 mW per channel in normal mode and 15 mW in low power mode. It is housed in a small footprint 24-pin SSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Fourth-order delta-sigma modulation architecture
• High dynamic range: 124 dB SNR @ 411 Hz bandwidth
• Low total harmonic distortion: -118 dB typical
• Clock jitter tolerant design

ADCs/DACs - Special Purpose Applications

• Geophysical measurement systems
• Sonar signal processing
• Multi-channel array configurations (when paired with CS5372)

ADCs/DACs - Special Purpose Part Context

The CS5371-BS belongs to the CS5371/CS5372 family of high-performance modulators. While the CS5371 provides a single channel, the CS5372 provides dual channels. These components are typically used in conjunction with dedicated digital filters to create complete high-resolution A/D conversion systems. The 'BS' suffix indicates the specific package and temperature grade variant within this product line.

ADCs/DACs - Special Purpose Replacement Considerations

For single-channel replacements, consider the CS5371A or CS5371-BSZ. For dual-channel requirements, the CS5372 series is the direct counterpart. System integration requires verifying compatibility with the associated digital filter, such as the CS5376.
