CS5320-KL - 24-Bit Sigma-Delta ADC | Cirrus Logic
MPN: CS5320-KL ✗ پایان تولیدCS5320-KL نمای کلی
An analog-to-digital converter, or ADC, converts a continuous analog voltage into a numeric representation for processing, storage, transmission, or control. A sigma-delta ADC uses oversampling, noise shaping, and digital filtering to achieve high resolution and dynamic range from a relatively narrow bandwidth. Within the semiconductor hierarchy, the CS5320-KL is an ADC, an analog mixed-signal IC, and a data-conversion device. Its low-frequency signal focus distinguishes it from wideband flash and successive-approximation converters.
The CS5320-KL provides a 24-bit conversion resolution, one analog input channel, sigma-delta modulation, and variable-bandwidth operation. Its intended signal range below 1500 Hz makes it appropriate for precision measurement rather than communications waveform capture. The 28-pin PLCC package provides a substantial lead count for reference, analog-input, digital-interface, control, and supply connections, while its 11.51 mm by 11.51 mm body supports conventional through-hole board assembly.
The CS5320 and CS5321 chipset architecture is designed for high dynamic range measurement below 1500 Hz. A dedicated analog input path supports external filtering and reference connections, while variable-bandwidth operation lets a designer balance output data rate against noise performance and system throughput. The analog-to-digital conversion architecture is suited to slow or quasi-static measurements where maximum resolution is more important than high-frequency sampling performance.
Typical uses include industrial process monitoring, precision instrumentation, audio and communications measurement, laboratory data acquisition, and embedded control systems that need a high-resolution conversion result. A system using the CS5320-KL would typically provide the reference and analog biasing required by the converter, condition the sensor or input signal, and route the digital conversion output to a controller or dedicated interface chipset.
Board design must preserve the accuracy of the reference and analog signal paths. Keep analog and digital return currents separated, place input and reference decoupling close to their associated pins, and use an anti-aliasing filter appropriate to the selected converter bandwidth. The PLCC package is not a fine-pitch surface-mount solution, so designers should also verify assembly temperature, lead coplanarity, and available PCB footprint before committing to a layout.
This product page combines the converter's core architecture and packaging details with practical comparison guidance, application fit criteria, and design considerations. It also distinguishes the verified CS5320-KL configuration from related chipset references without treating merely similar ADC functions as pin-compatible replacements.

کاربردهای معمول
CS5320-KL مناسب است برای 6 کاربردs: Industrial Process Measurement, Precision Instrumentation, Communications Signal Monitoring, Audio Amplitude Measurement, Laboratory Data Acquisition, Embedded Control and Monitoring.
Industrial Process Measurement
The CS5320-KL fits industrial process monitoring systems that measure slow sensor outputs requiring high resolution and good dynamic range. Its 24-bit sigma-delta conversion architecture and intended bandwidth below 1500 Hz are appropriate for pressure, temperature, level, and flow transducers that change slowly but require accurate amplitude representation. Place the converter behind a sensor-specific anti-alias filter, supply its reference from a stable low-noise source, and route serial conversion results to the plant controller. The main design trade-off is the 28-pin PLCC footprint, which occupies more board area than a compact mixed-signal ADC but simplifies through-hole assembly.

Precision Instrumentation
The CS5320-KL is appropriate for laboratory and bench instrumentation that measures low-frequency analog quantities with high resolution. The 24-bit result format and variable-bandwidth architecture allow conversion rate to be balanced against noise performance for different measurement spans. Use the analog input conditioning path to establish the required full-scale range and reference level, and design the output filter according to the selected bandwidth. Compared with a wideband ADC, this converter prioritizes dynamic range below 1500 Hz; compared with a small-package converter, it offers a straightforward 28-lead PLCC implementation with clearly separated analog and digital connections.
پیشنهادی
Communications Signal Monitoring
The CS5320-KL can support communications monitoring functions that measure envelope, level, or other slowly varying quantities below 1500 Hz. Its 24-bit sigma-delta architecture provides high dynamic range, while variable-bandwidth operation allows the designer to select a conversion profile suited to the measurement update rate. The analog path should include gain and filtering that prevent out-of-band energy from aliasing into the measurement. Because the device is intended for high-resolution low-frequency measurement rather than direct RF waveform digitization, system designers should use separate demodulation or frequency-conversion stages when the source contains higher-frequency content.
پیشنهادی
Audio Amplitude Measurement
The CS5320-KL is suitable for calibrated audio-level or acoustic measurement when the signal of interest lies below 1500 Hz and high-resolution amplitude data is more important than wideband audio capture. The 24-bit resolution supports detailed measurement of slowly varying levels, while the sigma-delta architecture emphasizes dynamic range. A practical implementation requires an input anti-alias filter, low-noise reference, and a digital path capable of receiving the converter's serial output. It should not be selected solely because the nominal resolution resembles an audio ADC; output rate, clocking, interface behavior, and the required input bandwidth must be verified from the manufacturer documentation.
پیشنهادی
Laboratory Data Acquisition
The CS5320-KL can serve as the conversion element in a laboratory data-acquisition channel designed for high-resolution monitoring of low-frequency sensors. Its one-input, 24-bit sigma-delta architecture simplifies multiplexing at a system level and its signal range below 1500 Hz supports slow-variable measurements. Designers should define the analog input range, reference voltage, conversion timing, and digital handshake from the manufacturer datasheet before finalizing the acquisition interface. The PLCC package provides accessible leads for inspection and rework, but its 11.51 mm by 11.51 mm body and 28-pin footprint require adequate board area and through-hole assembly clearance.
پیشنهادی
Embedded Control and Monitoring
The CS5320-KL fits an embedded monitoring controller that repeatedly measures a conditioned analog process or sensor signal and needs more resolution than a conventional 12-bit or 16-bit control-channel ADC. The 24-bit sigma-delta result and variable bandwidth provide flexibility for balancing update rate against noise, while the single input keeps the per-channel architecture straightforward. In a multichannel system, use an analog multiplexer or separate front ends ahead of the converter. Verify the digital interface and timing against the host controller, and place reference and bypass components close to their pins to prevent supply and reference disturbances from degrading the measurement.

یادداشت‌های طراحی
Route the analog input, voltage reference, and associated return paths away from digital clock and serial-data traces. Place input filtering and reference-decoupling components near the CS5320-KL rather than near the signal source. This matters because the converter's 24-bit resolution and high-dynamic-range architecture can expose reference noise and ground coupling that would be less visible at a lower resolution. Use the manufacturer system connection diagram to preserve the intended analog and digital topology.
Do not treat the 24-bit resolution as a guarantee of 24 useful bits at every conversion rate. Sigma-delta performance depends on selected bandwidth, output data rate, filter settling time, reference quality, and analog-noise spectrum. Use the manufacturer timing and frequency-response information to establish the usable noise bandwidth. Similarly, verify every one of the 28 PLCC pin functions from the pin table before laying out the PCB.
Design the analog front end as a complete signal chain. Select an anti-alias filter based on the intended signal below 1500 Hz, establish the required full-scale range, and calculate component tolerances for the gain and reference path. If a multiplexed input is used, allow enough settling time for the sigma-delta modulator and digital filter to produce a valid result after each channel change. These steps prevent channel errors that can resemble converter noise or nonlinearity.
