CS5351-BS 108 dB 192 kHz Audio ADC | Cirrus Logic
N.º de pieza: CS5351-BS ✗ Fin de vidaCS5351-BS Descripción general
An audio ADC is a data-converter IC that accepts analog left and right audio signals and converts them into digital words suitable for transmission, recording, playback, or digital signal processing. In the broader component hierarchy, the CS5351-BS is an ADC, a data converter, and a specialized digital-audio integrated circuit. Its integrated anti-alias filtering reduces the need for separate external analog filtering before the conversion stage.
The CS5351 uses a fifth-order, multi-bit Delta-Sigma modulator followed by digital filtering and decimation. This architecture is intended to support 24-bit conversion results at sample rates up to 192 kHz per channel. The manufacturer identifies the device as a complete analog-to-digital converter for digital audio systems, and the available product information describes overflow detection for both left and right channels, with the multiplexed overflow indication presented as an active-low open-drain signal on pin 15.
The device is intended for applications where accurate stereo capture and high-resolution digital representation are valuable. Typical uses include professional digital audio equipment, multichannel recording systems, consumer audio processors, digital mixers, and high-performance playback or monitoring equipment. The 192 kHz per-channel rate supports very high-bandwidth digital audio workflows, while the 108 dB dynamic-range figure defines the principal signal-to-noise performance target.
Because the CS5351-BS is an integrated converter, board layout and power-supply design remain important even when no external anti-alias filter is required. The analog and digital sections should be routed according to the manufacturer datasheet, with attention to grounding, decoupling, clock integrity, and keeping switching or high-current digital signals away from the analog inputs. The CS5351 family is marked NRND, so lifecycle planning should confirm availability or an approved replacement before beginning a long-running production design.
This page combines manufacturer information, distributor availability, lifecycle status, and application guidance to provide an engineering-focused overview. It also distinguishes documented CS5351-BS facts from parameters that require confirmation in the manufacturer datasheet, helping designers evaluate the converter without treating incomplete specifications as verified production data.

Aplicaciones típicas
CS5351-BS es adecuado para 6 aplicacións: Professional Digital Audio Recording, High-Resolution Digital Mixer, Digital Audio Monitoring System, Consumer High-Fidelity Audio Processor, Digital Amplifier Feedback Path, Audio Test and Measurement Equipment.
Professional Digital Audio Recording
The CS5351-BS fits professional stereo capture because it delivers 24-bit conversion, 108 dB dynamic range, and sample rates up to 192 kHz per channel. It can sit between the analog preamplifier and a digital recorder or DSP while performing sampling, A/D conversion, and anti-alias filtering in one device. The integrated fifth-order multi-bit Delta-Sigma path reduces the need for separate anti-alias circuitry, although the source impedance, reference quality, clock jitter, and PCB grounding remain important. Designers should verify the exact input range and supply requirements from the manufacturer datasheet rather than infer them from the 108 dB performance figure.
Recomendado
High-Resolution Digital Mixer
The CS5351-BS is appropriate for a digital mixer input stage requiring stereo 24-bit conversion at up to 192 kHz per channel. Its 108 dB dynamic range and integrated anti-alias filtering make it suitable for capturing multiple mixer channels through suitable line preamplifiers before routing the serial data into a mixing engine. The converter supports direct digital processing without a separate external anti-alias filter stage. Key implementation details include low-noise analog routing, a stable master clock, separate analog and digital supply considerations, and short traces that minimize coupling from mixer display, relay, and power-converter circuitry.
Recomendado
Digital Audio Monitoring System
The CS5351-BS can convert analog monitor-source signals into high-resolution digital data for a digital monitoring path. Its 24-bit output and 192 kHz maximum rate suit applications that preserve source detail during capture, while the 108 dB dynamic range provides a defined signal-to-noise target. The converter is used after a calibrated input stage and before a digital routing or processing engine. Because the verified data does not specify full-scale input or clock requirements, the design must use the manufacturer electrical data to set gain, anti-alias margins, and clock topology. Grounding and analog-digital partition layout remain critical to preserve the advertised performance.
Recomendado
Consumer High-Fidelity Audio Processor
The CS5351-BS can serve as the stereo ADC in a high-fidelity consumer audio processor that accepts analog line inputs and passes 24-bit digital audio to a DSP or DAC. Its integrated sampling and anti-alias function simplifies the converter block, while operation up to 192 kHz provides a path for high-rate processing. The design must still provide safe input attenuation or gain stages, a clean reference, and filtering appropriate to the selected source bandwidth. Low-level analog traces should remain away from display converters, switching regulators, and digital clock lines. The NRND lifecycle status should be checked against the product roadmap before new consumer platforms commit to the device.
Recomendado
Digital Amplifier Feedback Path
The CS5351-BS can provide high-resolution feedback or error-sensing in digital amplifier and feedback-control systems requiring stereo analog measurement. Its 24-bit resolution, 108 dB dynamic range, and 192 kHz per-channel capability support precise signal representation when the sampled result is processed digitally. The converter should be connected to a low-noise input stage with controlled source impedance and bandwidth. Clock jitter, analog supply noise, and layout coupling can affect the measurement path even when the converter itself operates within specification. Validate the selected -BS footprint and complete pinout against the manufacturer datasheet because the supplied search data does not provide every supply, clock, or electrical limit.
Recomendado
Audio Test and Measurement Equipment
The CS5351-BS is suitable for audio measurement equipment that converts left and right analog test signals into high-resolution digital data for analysis. Its 192 kHz maximum sample rate and 24-bit output support broadband audio capture, while 108 dB dynamic range provides a useful baseline for precision test systems. The analog source, attenuation network, and clock must be designed carefully to avoid becoming the limiting noise source. High-resolution conversion also benefits from controlled grounding, short analog traces, low-jitter clock distribution, and power rails that remain stable across the input range. The manufacturer datasheet remains necessary for verified input full scale, supply voltages, timing, and calibration considerations.

Notas de diseño
Partition the PCB so that the CS5351-BS analog input section, reference circuitry, and associated ground return are separated from digital clock, serial output, switching-regulator, and display circuitry. Keep the analog traces short and place input and bypass components close to their pins. Although the converter includes anti-alias filtering, the layout must still suppress high-frequency coupling before conversion. Review the manufacturer recommended layout and component placement in the datasheet before releasing the PCB.
Use a low-jitter, stable master clock and route it as a short, controlled-impedance clock network. The supplied data does not state the required clock frequency, so the frequency and timing must be taken from the manufacturer datasheet. Avoid routing the clock adjacent to analog inputs, keep return paths continuous, and use only the documented drive and termination method. If the converter operates near 192 kHz per channel, clock jitter and digital coupling become increasingly relevant to the usable audio signal chain.
Provide stable analog and digital supplies with the decoupling network specified by the manufacturer. The verified snippets do not provide supply-voltage values or current limits, so no unsupported voltage or dissipation calculation is included here. Place required capacitors at the relevant pins with short ground returns, use separate filtering paths for analog and digital rails where supported, and keep switching inductors and high-current paths away from the converter. Verify operating current and power dissipation against the datasheet for the chosen clock and sample-rate conditions.
Do not treat the 108 dB dynamic-range specification as permission to omit input gain control, source-impedance management, or an appropriate bandwidth plan. The converter also provides an active-low, open-drain overflow indication on pin 15; use the documented multiplexing and pull-up arrangement rather than driving that net as a push-pull output. Because the CS5351 family is NRND, confirm lifecycle status and obtain an approved second source before committing to a new production design.
Información de cumplimiento
The supplied verified snippets do not explicitly state compliance declarations for the exact CS5351-BS orderable part. Compliance must be confirmed through the current Cirrus Logic product page, the manufacturer datasheet, or an authorized distributor's material-declaration records.
