CS5372-BSZR

ADCs/DACs - Special Purpose Overview

The CS5372-BSZR is a two-channel, high dynamic range, fourth-order delta-sigma modulator manufactured by Cirrus Logic. Designed for geophysical and sonar applications, it features clock-jitter-tolerant architecture and fully differential analog inputs capable of handling 5 Vpp signals. The device operates with a single or dual power supply configuration, supporting VA+ levels of +5 V or +2.5 V. It generates an oversampled serial bit stream at 512 kbits per second when driven by a 2.048 MHz master clock. Key performance metrics include a typical signal-to-noise ratio of 127 dB within a 215 Hz bandwidth and total harmonic distortion of -118 dB.

ADCs/DACs - Special Purpose Feature Summary

• Fourth-order delta-sigma architecture optimized for high-resolution measurement between DC and 1600 Hz
• High dynamic range with SNR up to 127 dB @ 215 Hz bandwidth (2 ms output) and THD typically -118 dB
• Low power consumption: 25 mW per channel in normal mode and 15 mW per channel in low-power mode
• Supports multi-channel system configurations using combinations of CS5371 and CS5372 devices

ADCs/DACs - Special Purpose Applications

• Geophysical data acquisition systems
• Sonar signal processing
• High-resolution A/D measurement systems
• Multi-channel seismic data acquisition units

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'Z' suffix indicates RoHS compliance and halogen-free status as per standard Cirrus Logic naming conventions. Confirm the 'S' package code corresponds to the 24-pin SSOP form factor. Ensure the 'B' grade designation meets the specified temperature range of -40°C to +85°C. Cross-reference the specific ordering code against current manufacturer documentation to confirm availability and exact electrical tolerances.

ADCs/DACs - Special Purpose Selection Notes

Select the CS5372-BSZR for applications requiring two independent high-performance channels in a compact footprint. Pair with CS5376A or CS5378 digital filters to complete the A/D conversion chain. Ensure the external voltage reference provides less than 1 µVrms noise in the measurement bandwidth. Design anti-alias filters with a -3 dB corner at 8 kHz for normal mode or 4 kHz for low-power mode to maintain loop stability.

ADCs/DACs - Special Purpose Part Context

The CS5372 is part of the CS5371/CS5372 family of low-power, high-performance modulators from Cirrus Logic. While the CS5371 provides a single channel, the CS5372 integrates two channels into one 24-pin SSOP package. This family is specifically engineered to replace older discrete solutions in precision measurement environments, offering superior dynamic range and lower power dissipation compared to previous generation audio or industrial ADCs.
