CS4223-KS - 24-Bit 105dB Stereo Audio Codec | Cirrus Logic
부품 번호: CS4223-KS ✗ 단종CS4223-KS 개요
An audio codec is an interface integrated circuit that converts between analog audio signals and digital audio data. The CS4223 belongs to the broader codec hierarchy, which includes digital-to-analog converters, analog-to-digital converters, audio interface ICs, and signal-conversion semiconductors. In this device, stereo delta-sigma ADC and DAC sections share the same integrated package and serial digital audio connection.
The primary verified performance features are 24-bit resolution, 105 dB dynamic range, stereo conversion, a 24-bit serial interface, operation from one +5 V supply, and low power consumption. These characteristics suit professional audio equipment, multichannel sound systems, consumer audio electronics, industrial monitoring, and embedded audio platforms where analog audio must be captured or reproduced using a digital signal path.
The CS4223/4 family uses delta-sigma conversion techniques, allowing analog stereo signals and digital audio data to share a compact mixed-signal package. The CS4223-KS distributor description identifies this specific option as a 24-bit audio codec without volume control. That distinction is important because volume-control functionality must be verified in the manufacturer documentation before assuming equivalent behavior between CS4223 and CS4224 variants.
Typical circuit roles include receiving digital audio data for conversion to stereo analog outputs and accepting stereo analog inputs for conversion to digital data. System designers must provide suitable input and output filtering, stable analog supply and ground distribution, correct serial-interface timing, and signal routing appropriate to the codec's application. The single +5 V supply simplifies rail planning, although analog and digital return-current paths still require careful PCB partitioning.
Before layout, compare the exact CS4223-KS pinout and electrical limits against the selected schematic revision. The public search results identify the package as 28-pin SSOP, but they do not provide a complete verified pin table in the supplied data; no pin names are therefore inferred here. Likewise, sample rate, clock range, analog input and output range, and recommended external component values require confirmation in the manufacturer datasheet.
This product page consolidates the verified distributor descriptions, manufacturer-family data, package information, and practical selection considerations for the CS4223-KS. It separates confirmed specifications from unavailable parameters and focuses comparison on genuine same-package family options rather than presenting unrelated codecs as drop-in replacements.

일반적인 애플리케이션
CS4223-KS 적합 용도: 6 애플리케이션s: Stereo Digital Audio Recording, Professional Audio Playback, Digital Audio Interface and Conversion, Consumer Audio Equipment, Industrial Audio Monitoring, Legacy Audio Equipment Restoration.
Stereo Digital Audio Recording
The CS4223-KS fits a stereo recording front end because it combines a 24-bit analog-to-digital converter with a 24-bit digital-to-analog converter and a 105 dB dynamic-range rating. According to the Cirrus Logic datasheet, the converters use delta-sigma technology and operate from one +5 V supply. The codec can receive analog stereo input, expose digital audio data through its 24-bit serial interface, and support monitoring through the integrated DAC section. The design should use a stable +5 V source and keep analog input traces away from high-speed digital signals. The exact sample rates, clock requirements, input range, and anti-alias filter values are not present in the supplied data and must be taken from the manufacturer documentation.
추천
Professional Audio Playback
The CS4223-KS can support a stereo playback subsystem where digital source data is converted to analog audio with 24-bit resolution and a 105 dB dynamic-range specification. The integrated stereo DAC avoids assigning separate converter packages to each output channel, while the serial interface provides a compact connection to a digital audio source. Because the CS4223 variant is identified as operating without volume control, gain adjustment should be implemented elsewhere in the signal chain. According to the Cirrus Logic family documentation, the device runs from a single +5 V supply and uses delta-sigma conversion. Output filtering, clocking, and analog grounding must follow the reference application circuit.
추천
Digital Audio Interface and Conversion
The CS4223-KS is suitable for equipment that must translate between analog stereo audio and a 24-bit digital serial stream. Its integrated ADC and DAC sections allow a shared digital audio architecture to support both capture and playback without separate converter packages for every channel. The 105 dB dynamic-range figure provides a useful selection criterion for mixed-signal equipment, while the single +5 V operating requirement simplifies the power tree. System designers must still allocate a clean analog supply path, implement the manufacturer-recommended input and output filters, and verify supported serial formats and clock modes. The supplied sources do not state the complete digital interface timing table.
추천
Consumer Audio Equipment
The CS4223-KS can be used in consumer audio products that require integrated stereo conversion rather than separate ADC and DAC packages. Its 24-bit conversion resolution, 105 dB dynamic range, and low-power single-supply operation align with compact playback and recording products. The manufacturer identifies the part as an audio codec without volume control, so the product architecture needs a separate gain-control or attenuation strategy when user-adjustable volume is required. As the Cirrus Logic datasheet describes delta-sigma converters, external analog filtering and careful PCB partitioning remain essential. Package availability and lifecycle should also be checked before committing a modern consumer design to this legacy codec.
추천
Industrial Audio Monitoring
The CS4223-KS can serve in industrial monitoring equipment that captures stereo analog activity or returns digital audio as an analog signal. The integrated 24-bit ADC and DAC provide a consistent conversion format, while the 105 dB dynamic-range specification is useful when designing measurement, communications, or acoustic-monitoring equipment. The single +5 V supply can simplify installation inside compact control systems, but industrial deployments must verify temperature limits and long-term availability because those data were not included in the supplied sources. Grounding should separate converter returns from digital processor currents, and input protection must be designed around the manufacturer-supported analog range. Exact sample-rate and clock configuration remain subject to the manufacturer datasheet.
추천
Legacy Audio Equipment Restoration
The CS4223-KS is particularly relevant when restoring or maintaining legacy equipment that already uses the CS4223/4 codec architecture. Its 28-pin SSOP package, 24-bit serial interface, and single +5 V supply support board-level replication when the original schematic specifies this variant. Because the available market status appears inconsistent across distributor and broker listings, purchasers should confirm whether the part is new, factory-reconditioned, or sourced through brokerage before installation. Matching the original footprint alone is insufficient: pin names, clock polarity, analog levels, and support components must match the archived design. The absence of volume control must also be confirmed against the replaced assembly.

설계 노트
Route analog input and output connections away from the 24-bit serial clock and data lines, and keep the codec ground return continuous beneath the device where the manufacturer layout guidance permits. The verified family operates from a single +5 V supply, but analog and digital currents still need separate return paths to prevent converter noise from coupling into the audio channels. Use the manufacturer reference layout for decoupling, filter placement, and exposed analog input or output routing.
Provide a low-noise +5 V source with local high-frequency bypass placed close to the supply pins according to the manufacturer recommendation. Do not assume that a single-supply codec eliminates the need for power filtering because upstream switching converters can inject noise through the supply rail. Validate the actual power-consumption figure and operating limits from the datasheet because those numerical values are absent from the supplied search data.
Do not substitute a CS4224-family part solely because it has the same 28-pin SSOP outline; the verified distinction is that CS4223 operates without volume control while CS4224 includes that function. Before a drop-in substitution, compare the complete pinout, serial-clock requirements, analog input and output ranges, recommended filters, and absolute maximum ratings. The suffix also determines ordering-code characteristics that were not available in the supplied data.
Keep the digital audio bus short, route clock and data consistently, and terminate the interface according to the host device and manufacturer interface specification. The supplied data confirms a 24-bit serial interface but does not provide its voltage standard, clock frequency, edge requirements, or supported serial modes. Those timing and electrical details must be verified before layout sign-off or a host-device swap.
