CS5580-ISZ 概述
Sigma-delta ADCs (also written as sigma-delta or delta-sigma) are a class of oversampling converters that trade raw speed for very high resolution and excellent noise rejection. They integrate a modulator and a digital filter, pushing quantization noise out of the baseband and producing low-noise, high-resolution output. In the IC hierarchy, the CS5580-ISZ sits as an ADC inside the Data Acquisition category, which itself belongs to Integrated Circuits (ICs) and ultimately to the broader signal-chain and power-management semiconductor family.
Key features include 16-bit resolution, a single differential or single-ended input channel, sigma-delta modulator architecture, and selectable data interfaces (serial and parallel). The 24-SSOP package provides a compact surface-mount footprint suitable for industrial control boards, instrumentation front-ends, and process-control modules. Operating from a standard 5V analog supply, the converter is designed for use with downstream microcontrollers, DSPs, or FPGA-based acquisition engines.
The CS5580's high-throughput delta-sigma architecture enables precise digitization of low-frequency, high-precision analog signals such as transducer outputs, weigh-scale bridge signals, and temperature-conditioned sensor measurements. The combination of 16-bit resolution with sigma-delta noise shaping makes it particularly well suited to measurement applications that demand low noise and excellent linearity rather than high sample rates.
Typical applications include industrial process control, weigh scales and load-cell digitizers, temperature measurement systems, and precision sensor front-ends. The wide compatibility with both serial and parallel host interfaces also makes it attractive for legacy system upgrades where an existing parallel bus is available.
When designing with the CS5580-ISZ, ensure that input signals are properly buffered and that the reference voltage is low-noise and well decoupled. Layout the analog and digital grounds as separate planes joined at a single point to avoid coupling modulator switching noise into the analog front end.

典型应用
CS5580-ISZ 适用于 7 应用s: Industrial Process Control, Weigh Scales and Load-Cell Digitizers, Temperature Measurement Systems, Precision Sensor Front-Ends, Data Acquisition Modules, Medical Instrumentation, Industrial Sensor Signal Conditioning.
Industrial Process Control
The CS5580-ISZ's 16-bit sigma-delta architecture delivers the resolution and noise rejection that 4-20 mA loop and process-variable digitizing demands. In a typical PLC analog-input module, the converter sits behind a front-end instrumentation amplifier and conditions signals from thermocouples, RTDs, or pressure transducers; the sigma-delta modulator's oversampling pushes quantization noise out of the baseband, improving effective resolution at low signal bandwidths. The dual serial/parallel interface allows the same chip to drop into legacy parallel-bus PLCs and modern serial-only controllers, supporting both brownfield retrofits and new designs.
推荐
Weigh Scales and Load-Cell Digitizers
Weigh-scale designs require high-resolution digitizing of low-frequency bridge signals with excellent common-mode rejection. The CS5580-ISZ's sigma-delta modulator architecture naturally rejects 50/60 Hz line noise through its digital filter, making it well suited to load-cell front-ends. Place the converter after a low-noise instrumentation amp (e.g., INA128-class) and a precision reference; the 16-bit resolution supports kilogram-scale commercial weighing while the 24-SSOP package keeps the BOM footprint compact for embedded scale modules.
推荐
Temperature Measurement Systems
Precision temperature acquisition with thermocouples, RTDs, or semiconductor sensors demands high resolution at low sampling rates - the exact regime where sigma-delta converters excel. The CS5580-ISZ's 16-bit resolution and integrated digital filtering provide stable readings in noisy industrial environments, while the 24-SSOP package allows compact multi-channel scanner boards. The dual serial/parallel interface simplifies integration with both microcontroller-based and DSP-based temperature loggers used in environmental chambers and process heating systems.
推荐
Precision Sensor Front-Ends
Strain gauge, pressure transducer, and flow-meter front-ends benefit from the CS5580-ISZ's combination of 16-bit resolution and sigma-delta noise shaping. The converter's high common-mode rejection and integrated digital filter simplify the analog front-end, allowing designers to omit external anti-aliasing filters in many cases. The 24-SSOP surface-mount package supports automated assembly on high-density sensor-interface PCBs used in medical, aerospace, and industrial-automation systems.
推荐
Data Acquisition Modules
Modular data-acquisition cards for PCI/PCIe backplanes, USB-based DAQs, and Ethernet-based remote-IO blocks use the CS5580-ISZ as a per-channel precision ADC. Its single-channel 16-bit sigma-delta core enables synchronized low-frequency sampling when multiple converters are clocked together, and the dual serial/parallel interface lets the same silicon drop into legacy parallel-bus DAQ architectures as well as newer serial-FPGA designs. The 24-SSOP footprint keeps channel density high on multi-channel acquisition boards.
推荐
Medical Instrumentation
Patient monitoring and diagnostic instrumentation require low-noise, high-resolution digitization of biopotential and physiological signals. The CS5580-ISZ's sigma-delta architecture, integrated digital filtering, and 16-bit resolution support accurate capture of low-frequency ECG, respiration, and temperature channels while rejecting mains-frequency interference. The 24-SSOP surface-mount package suits compact medical-device PCBs, and the dual serial/parallel interface allows flexible host-MCU integration.
推荐
Industrial Sensor Signal Conditioning
Standalone sensor-signal-conditioning modules in factory automation use the CS5580-ISZ to digitize analog 0-10 V or 4-20 mA inputs. The 16-bit resolution allows accurate scaling of industrial sensor spans, while the sigma-delta architecture's noise shaping provides stable readings in electrically noisy panel environments. The 24-SSOP package is well matched to DIN-rail-mounted signal-conditioner PCBs, and the dual interface option eases integration with fieldbus and Ethernet-IO gateways.

设计说明
Estimated: the CS5580-ISZ's sigma-delta modulator is sensitive to digital switching noise. Use a single-point star ground connecting the analog and digital ground planes directly under the converter's GND pin. Place the input-coupling capacitors, reference decoupling (typically 10uF + 0.1uF), and analog supply bypass within 5 mm of the IC. Route digital interface traces away from the analog input pins and reference traces to avoid capacitive coupling of switching edges into the analog front end.
Provide clean, low-noise analog and digital supplies to the CS5580-ISZ. The reference voltage is the dominant noise source in any sigma-delta measurement; use a low-noise precision reference (such as the REF02 or equivalent) with adequate output bypassing. Avoid switching DC-DC converters near the ADC unless followed by a low-dropout linear post-regulator and pi-filter, as ripple from a switching regulator directly degrades effective resolution.
Drive the CS5580-ISZ analog input through a low-noise, low-offset buffer or instrumentation amplifier (e.g., INA128-class). Sigma-delta converters sample at high oversampling ratios, so the input must settle within the modulator's acquisition window. For load-cell and weigh-scale designs, use a low-pass RFI input filter at the terminal block to suppress out-of-band interference that could otherwise alias into the baseband through the modulator's sampling process.
Do not assume the CS5580-ISZ and CS5581-ISZ are unconditionally pin-compatible. Although the IC-Components listing groups CS5580, CS5581, and CS5582 as similar-function Cirrus Logic parts, the exact pinout, resolution, and throughput can differ between family members. Always cross-check the target part's datasheet against the CS5580 datasheet before substituting in production. Similarly, cross-brand 24-SSOP 16-bit sigma-delta ADCs from non-Cirrus vendors must be verified pin-by-pin.
