CS4224-BS - 24-Bit 105dB Stereo Audio Codec | Cirrus Logic
部品番号: CS4224-BS ✗ 生産終了CS4224-BS 概要
An audio codec is a mixed-signal semiconductor that converts signals between the analog and digital domains. The CS4224 family belongs to the codec hierarchy, which includes audio codecs, interface ICs, data converters, and broader signal-processing semiconductors. Its integrated ADC and DAC reduce the number of external conversion components needed in professional audio, communications, and digital audio equipment.
Key features include 24-bit conversion resolution, a stated 105 dB signal-to-noise characteristic, integrated volume control, stereo conversion channels, and operation from one +5 V supply. These characteristics make the device appropriate for audio capture and playback systems where a compact, dedicated codec is preferable to discrete converters. Its integrated volume function can simplify analog-level control, although system-level gain planning must prevent overload and preserve headroom.
The CS4224-BS uses delta-sigma conversion to implement the analog-to-digital and digital-to-analog functions. According to the Cirrus Logic CS4224 family datasheet, the architecture is designed for high-performance 24-bit audio operation in a single integrated device. Exact interface timing, clock requirements, analog performance, input and output topology, and recommended external component values must be confirmed against the manufacturer datasheet before layout or firmware is finalized.
Typical uses include digital audio consoles, multimedia and communications equipment, sound-card signal paths, and other stereo audio systems requiring simultaneous analog capture and playback. In such systems, the codec can sit between analog microphones or line-level sources and a digital audio processor, while digital program audio is converted back to analog for monitoring or amplification.
Designers should follow the manufacturer pinout and reference connection exactly, paying particular attention to analog grounding, supply decoupling, clock routing, and the treatment of unused inputs and outputs. Because the verified product listing identifies the CS4224-BS as a 28-SSOP and describes it as a 24-bit, 105 dB codec with volume control, those details can be cited confidently; additional electrical values remain subject to the datasheet.
This page consolidates the verified distributor identity, pricing reference, package information, family-level description, drop-in evidence, and practical design guidance. It also distinguishes confirmed specifications from parameters that still require verification, providing a more useful engineering record than an uncontextualized distributor listing.

主な用途
CS4224-BS の用途: 6 件s: Digital Audio Console, Professional Audio Interface, Digital Sound Card, Multimedia Audio Subsystem, Communications Audio Terminal, Audio Recording and Playback Module.
Digital Audio Console
The CS4224-BS fits a stereo digital audio console because it combines a 24-bit ADC, a 24-bit DAC, and integrated volume control in one 28-pin SSOP device. A console can route microphone or line-level inputs into the ADC, transfer the resulting digital samples to a mixer or DSP, and convert playback audio back to analog through the DAC. Its stated 105 dB signal-to-noise characteristic provides useful dynamic-range headroom for multi-channel professional workflows. The single +5 V architecture also simplifies system power planning compared with dual-rail designs. Before schematic capture, engineers must verify the supported digital interface, master-clock requirements, input and output ranges, supported sample rate, and exact analog routing in the manufacturer datasheet.
おすすめ
Professional Audio Interface
The CS4224-BS is appropriate for a professional audio interface requiring simultaneous analog capture and playback in a compact mixed-signal device. Its 24-bit ADC and DAC support high-resolution recording and monitoring, while the stated 105 dB rating helps preserve signal integrity across the conversion path. The integrated volume control can simplify channel-level adjustment, although gain staging must be handled carefully to avoid clipping in the converter or downstream amplifier. A practical implementation uses one +5 V supply and separates analog and digital return currents around the codec. Sample-rate support, reference-clock topology, analog input impedance, and recommended bypass components remain datasheet-dependent and should be confirmed before layout.
おすすめ
Digital Sound Card
The CS4224-BS can support a stereo sound-card signal path by accepting analog line-level audio, converting it at 24-bit resolution, and providing a matched digital-to-analog playback path. The integrated volume function is useful when firmware or analog control must adjust output level, while the 105 dB signal-to-noise specification supports clean capture and monitoring. Its 28-pin SSOP package can suit established legacy sound-card layouts where an exact footprint is already present. Engineers should confirm whether the CS4224-BS digital interface matches the host controller, and whether a separate clock source or synchronization architecture is required. Ground partitioning, bypass-capacitor placement, and analog trace routing should follow the manufacturer's application guidance.
おすすめ
Multimedia Audio Subsystem
The CS4224-BS can form the core of a multimedia audio subsystem where analog capture and playback are consolidated around a dedicated codec. Its 24-bit conversion resolution provides more headroom than a basic 16-bit interface, and the stated 105 dB rating is useful when the same codec must serve both communication capture and program-audio playback. Integrated volume control simplifies one stage of level management in a mixed-source system. The single +5 V supply requirement can reduce board-level complexity, but the host processor, data interface, clocking plan, and analog amplifiers remain separate design tasks. Validate the exact supported sample rates, digital data format, input type, and output loading against the Cirrus Logic documentation before selecting this codec.
おすすめ
Communications Audio Terminal
The CS4224-BS is suitable for communications terminals that require a local analog microphone path and digital-audio processing. The stereo ADC can digitize line-level or appropriately conditioned voice sources, while the stereo DAC supports monitoring or loudspeaker-feed generation. The 24-bit resolution preserves additional processing margin, and the 105 dB stated signal-to-noise rating can support clean speech capture in well-designed analog channels. Integration in a 28-pin SSOP reduces the number of separate converter packages. The main engineering constraints are clock synchronization, microphone or line conditioning, echo-cancellation requirements, and output amplification. These functions cannot be inferred from the distributor data, so the complete signal chain must be validated in the datasheet and system-level test plan.
おすすめ
Audio Recording and Playback Module
The CS4224-BS fits a compact recording-and-playback module where one codec must support two-way analog audio. Digital samples from the 24-bit ADC can be stored or processed externally, while the 24-bit DAC returns playback content to analog circuitry. The integrated volume control offers a local adjustment point, and the stated 105 dB rating provides a strong starting point for low-noise capture and monitoring designs. Its single +5 V operation and 28-pin SSOP package can simplify board integration in legacy-compatible equipment. For implementation, verify the supported clock and sample-rate combinations, digital interface voltage, analog input topology, output load, and recommended external filter components. Ensure the layout preserves the separation of analog and digital return paths.

設計ノート
Follow the manufacturer datasheet layout exactly for supply bypass, analog grounding, and clock routing. Place the required input and output capacitors directly at the associated pins, keep digital return current out of the analog input reference path, and use a continuous ground plane unless the datasheet prescribes a split-plane arrangement. Because the individual CS4224-BS pin functions were not exposed in the verified search data, do not begin PCB routing from the 28-SSOP outline alone.
Treat clock and digital data traces as potentially high-speed signals even though the exact supported interface timing was not supplied. Route clocks over a continuous reference plane, minimize stubs and unnecessary vias, and keep switching-node or processor-clock sources away from analog inputs. Match the codec's digital interface voltage to the host device and confirm edge-rate requirements, series termination, and ground references in the datasheet before assigning impedance rules.
Do not substitute a similarly named codec based only on the 24-bit and 105 dB description. The CS4224-BS includes stereo ADC and DAC functions, volume control, single +5 V operation, and a specific 28-SSOP package, so the replacement must satisfy all of those requirements. Verify exact pin names, exposed connections, supply tolerances, sample-rate support, clock mode, and analog levels. Also confirm lifecycle status because the supplied web evidence does not establish whether the part is active, NRND, or obsolete.
コンプライアンス情報
The supplied verified search results do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because the product is an audio interface IC and no automotive qualification was identified.
