CS5372-BS - 24-Bit Dual ΔΣ Modulator | Cirrus Logic
MPN： CS5372-BS ✓ 啟用中CS5372-BS 概覽
A delta-sigma modulator is a signal-conversion building block that noise-shapes quantization error away from the measurement band. The CS5372 belongs to the broader delta-sigma modulator family within data-conversion ICs, with the CS5376 digital filter forming the companion conversion stage in the manufacturer-described measurement system. This separation allows the analog front end and digital filtering to be optimized independently.
The CS5372-BS provides 24-bit resolution and a maximum serial conversion rate of 512 kS/s across two channels. Its fourth-order architecture is intended for high-dynamic-range acquisition, while the low-power design supports extended measurement-system run times. The serial interface simplifies connection to digital filter and processing hardware, and the 24-pin SSOP package supports compact, surface-mounted instrumentation.
The device is intended to be used with the Cirrus Logic CS5376 digital filter to create a complete high-resolution analog-to-digital measurement system. This architecture is particularly relevant when sensor outputs require narrow-band extraction, strong rejection of out-of-band noise, and high resolution without requiring a conventional high-speed flash converter directly at the analog input.
Typical applications include geophysical survey instruments, sonar measurement front ends, seismic data-acquisition systems, precision industrial monitoring, and low-frequency sensor instrumentation. In these systems, the CS5372-BS can convert differential or single-ended analog sensor signals into a high-resolution digital bitstream for subsequent filtering and processing.
Designers should follow the manufacturer pin-description and application tables when assigning analog inputs, references, clocking, and digital interfaces. Decoupling, grounding, and clock implementation directly affect modulator performance, so the recommended layout and component values should be taken directly from the manufacturer datasheet and its CS5376 companion-filter recommendations.

典型應用
CS5372-BS 適用於 6 應用s: Geophysical Survey Instrumentation, Sonar Signal Acquisition, Seismic Data Acquisition, Precision Industrial Sensor Monitoring, Low-Level Environmental Measurement, High-Resolution Measurement Test Equipment.
Geophysical Survey Instrumentation
The CS5372-BS fits two-channel geophysical measurement systems requiring high-resolution conversion of low-level sensor signals. Its fourth-order delta-sigma architecture and 24-bit serial interface are intended to work with the CS5376 digital filter, allowing out-of-band noise reduction and high-resolution extraction from seismic or other geophysical waveforms. The two channels reduce the number of separate modulator devices needed for paired measurements. In a field instrument, the CS5372-BS can feed the CS5376 for digital decimation before storage or processing. Designers should implement the manufacturer reference and filter network, preserve clean analog grounding, and use the specified clock and decoupling arrangements to prevent environmental noise from limiting the measurement chain.
推薦
Sonar Signal Acquisition
The CS5372-BS is suitable for sonar acquisition front ends that need two high-resolution measurement channels and a serial interface to a companion digital filter. The fourth-order delta-sigma stage supports narrow-band signal extraction, while the CS5376 performs digital filtering and decimation to create a complete measurement system described by the manufacturer. Its conversion capability of up to 512 kS/s provides a defined digital-output rate for downstream processing. In a sonar receiver, the modulator should be placed close to the front end and configured according to the manufacturer reference. Keep sensitive analog nodes compact, follow the prescribed grounding scheme, and validate clock jitter and reference stability across the operating temperature range.
推薦
Seismic Data Acquisition
The CS5372-BS can serve as the analog-to-digital modulator in portable seismic acquisition equipment where two sensor channels, low power, and high resolution are important. Its 24-bit serial output is designed for connection to the CS5376 companion digital filter, which completes the high-resolution conversion system described by the manufacturer. The fourth-order architecture is suited to extracting wanted low-frequency or narrow-band energy from broadband sensor output. Engineers should use the recommended analog input network, external filtering, reference implementation, and bypass capacitors from the manufacturer documentation. Clock and layout choices also matter because the seismic signal chain can have wide dynamic range, making reference drift, ground coupling, and clock jitter important system-level considerations.
推薦
Precision Industrial Sensor Monitoring
The CS5372-BS is appropriate for industrial monitoring equipment that measures two low-level analog channels and requires a high-resolution digital representation. Its fourth-order delta-sigma modulation and 24-bit serial interface permit use with the CS5376 digital filter for final decimation and filtering. This can suit process-control diagnostics, condition-monitoring instruments, and precision test systems that benefit from separating analog modulation from digital filtering. The component should be implemented using the manufacturer reference circuit, including its recommended input filtering, reference, grounding, and decoupling arrangements. Because industrial environments can introduce conducted noise and ground shifts, engineers should evaluate shielding, isolation, analog routing, and clock-source quality rather than assuming the nominal converter resolution alone determines measurement accuracy.
推薦
Low-Level Environmental Measurement
The CS5372-BS can be used in environmental monitoring instruments that require simultaneous acquisition of two sensor outputs at high resolution. Geophones, vibration sensors, and other low-level transducers benefit from a fourth-order delta-sigma front end, particularly when the system can employ the CS5376 for narrow-band filtering and decimation. The CS5372-BS supports a 24-bit serial transfer at rates up to 512 kS/s, leaving digital processing to the companion filter. Portable deployments also benefit from the low-power positioning of the device. Use the manufacturer-specified analog network and grounding scheme, and pay particular attention to moisture, contamination, reference stability, and EMI around the sensitive inputs because environmental measurement accuracy can be degraded by sources outside the converter itself.
推薦
High-Resolution Measurement Test Equipment
The CS5372-BS is a practical front-end choice for test and measurement instruments requiring 24-bit resolution, two channels, and a documented path to a companion digital filter. The manufacturer identifies the CS5376 as the intended partner for producing a high-resolution analog-to-digital system, while the modulator supports serial rates up to 512 kS/s. This arrangement allows instrumentation designers to concentrate high-resolution conversion in the analog domain and perform decimation, filtering, calibration, and analysis digitally. PCB implementation should closely follow the manufacturer layout because analog leakage, clock quality, reference noise, and ground separation can affect the complete measurement path. Use the pin-description and application tables in the manufacturer datasheet when connecting transducers, external filters, clock circuitry, and the CS5376.

- Manufacturer-described companion-filter path (對比CS5368-DQZR)
設計說明
Implement the analog input, reference, clock, and digital-output sections according to the manufacturer layout guidance. Keep sensitive analog traces short, route them away from high-current or switching circuitry, and maintain the recommended separation between analog and digital ground connections. The CS5372-BS relies on a companion digital filter such as the CS5376, so the serial-interface routing between the two devices should be checked for timing margin, signal integrity, grounding, and connector or via assignments.
Treat clock quality as part of the measurement chain. A stable clock with low jitter helps preserve the modulator's effective performance, while excessive clock noise can increase error in the converted signal. Follow the manufacturer's clock-generation and decoupling recommendations, avoid routing clock traces beside sensitive analog inputs, and verify the complete interface between CS5372-BS channels and the CS5376 digital filter under operating temperature and supply-load conditions.
Do not substitute a related CS537x device based only on the family name. Channel count, package suffix, serial timing, supply voltage, clocking, reference implementation, and pin assignment must all be checked. The CS5371 is a one-channel member, CS5372A-ISZ is a related but distinct ordering, and CS5372-BSR is a closely named ordering variant. Use the manufacturer ordering table and pin descriptions before treating any of them as an interchange for the CS5372-BS.
