CS4222-BS - 20-Bit Stereo Audio Codec | Cirrus Logic
MPN: CS4222-BS ✗ Akhir HayatCS4222-BS Ringkasan
An audio codec is a mixed-signal semiconductor that converts audio between digital data and analog voltage signals. Within the broader integrated-circuit hierarchy, a codec belongs to the interface and audio-converter class, combining an ADC, DAC, volume control, and associated analog circuitry in one device. The CS4222 family therefore reduces the number of separate converters required in a stereo audio system while simplifying synchronization and analog-output implementation.
The verified manufacturer information identifies a 20-bit resolution, four-channel audio configuration, delta-sigma conversion architecture, and single +5 V operation. Its on-chip output buffer produces differential line-level outputs for the left and right channels. The documented nominal output is 2.83 Vpp, or 1 Vrms, for each single-ended output at full-scale digital input, with a 2.3 V common-mode voltage. The corresponding differential signal is 5.66 Vpp, or 2 Vrms).
The CS4222-BS also incorporates volume control, allowing playback amplitude to be adjusted within the codec rather than solely through external analog gain stages. This integration can simplify system architecture, but the exact control interface, supported audio data formats, converter performance, clock requirements, and recommended external networks must be confirmed from the manufacturer datasheet before layout or firmware development. Those detailed values are not present in the supplied verified extracts and are therefore not inferred here.
Typical implementation roles include legacy stereo multimedia systems, audio capture and playback modules, digital mixing equipment, and embedded audio subsystems requiring separate transmit and receive paths. In such equipment, the codec can accept digital audio at its ADC input and provide amplified analog left and right outputs for external coupling, headphone, or line-stage circuitry. Its differential outputs may offer better rejection of common-mode noise than single-ended outputs when paired with a balanced receiver.
A critical design consideration is that the codec cannot be evaluated from resolution alone. Designers should verify the complete interface protocol, sample-rate range, clocking scheme, analog input range, output-load capability, power sequencing, and external component recommendations in the manufacturer datasheet. The documented 10 kΩ output loading must also be respected because heavier loads can alter output level and distortion even if the nominal operating voltage remains correct.
This product page consolidates verified CS4222-BS specifications, distributor availability references, package information, and engineering guidance into one searchable source. It also separates documented data from unresolved parameters, helping engineers avoid unsupported assumptions while evaluating this audio codec for a new or legacy PCB design.

Aplikasi Biasa
CS4222-BS patut untuk 6 aplikasis: Stereo Audio Playback, Stereo Audio Capture, Legacy Multimedia Audio Module, Digital Mixing Console, Industrial Audio Control Panel, Audio Interface Retrofit.
Stereo Audio Playback
The CS4222-BS is suitable for a stereo playback subsystem that requires digital-to-analog conversion, integrated volume control, and differential line-level outputs. Its 20-bit DAC architecture and nominal 2.83 Vpp, or 1 Vrms), single-ended output give the downstream receiver a defined signal level, while the paired differential outputs provide 5.66 Vpp, or 2 Vrms). The 28-pin SSOP implementation consolidates several analog functions, although the final load stage must respect the documented 10 kΩ output-load recommendation unless additional drive capability is verified.
Disebarkan
Stereo Audio Capture
The integrated stereo ADC path makes the CS4222-BS applicable to analog audio capture modules that must convert left and right line-level signals into digital data. Its documented 20-bit stereo conversion resolution supports precision-oriented designs, while operation from one +5 V supply can simplify mixed-signal power planning. Designers still need to verify the supported sample rates, digital audio format, analog input range, anti-alias filtering, clock source, and input coupling requirements in the complete manufacturer datasheet before finalizing the analog front end.
Disebarkan
Legacy Multimedia Audio Module
The CS4222-BS can fit a legacy multimedia audio module requiring a single-package codec with both recording and playback capability. Its 28-pin SSOP package, integrated volume control, four-channel configuration, and single +5 V operation simplify board partitioning compared with a design using discrete ADC and DAC devices. For repair and modernization projects, designers should preserve the original clock topology and pin functions, and they should confirm whether obsolete-market inventory includes date codes, traceability, and manufacturer-authorized documentation.
Disebarkan
Digital Mixing Console
A digital mixing console can use the CS4222-BS as a local stereo conversion and level-control element when its documented digital interface matches the console architecture. Integrating the DAC, ADC, and volume control reduces interstage wiring and keeps the analog output stage close to the digital signal path. The designer must still account for channel routing, sample-rate compatibility, clock distribution, latency, and grounding. Differential outputs are useful in a studio environment where ground potential differences could affect a single-ended receiver.

Industrial Audio Control Panel
The CS4222-BS may serve in an industrial audio-control panel that plays system announcements while capturing microphone or line-level feedback. The stereo ADC and DAC paths provide a consolidated mixed-signal interface, and differential outputs can improve robustness when routed toward a balanced amplifier over longer internal wiring. Because lifecycle status and several detailed operating parameters are unresolved in the supplied extracts, an industrial implementation should include supply filtering, ESD protection, startup testing, and a sourcing plan for long-term maintenance.
Disebarkan
Audio Interface Retrofit
The CS4222-BS is useful in retrofit work where an existing board expects a 28-pin SSOP stereo codec with differential outputs and a +5 V analog supply. Retaining the original component can minimize PCB changes and preserve calibrated analog behavior when no verified modern replacement has the same pin assignment and digital protocol. Before installation, engineers should compare revision-specific schematics, test all supply rails, inspect socketed parts for corrosion, and confirm clock and data-line timing with an oscilloscope because silent digital-interface errors can resemble converter faults.

Catatan Desain
Route the analog input, analog output, and digital clock or data paths with their respective return paths in mind. The verified material identifies differential outputs and a 2.3 V common-mode level, so receiver grounding should be compatible with those outputs. Keep the codec and its documented input and output networks close together, maintain a quiet analog return, and avoid routing switching-node traces beneath the audio circuitry. The exact component placement must follow the manufacturer’s reference layout because it was not included in the supplied extracts.
Plan the +5 V rail for both converter operation and output-buffer requirements, then follow the manufacturer’s recommended bypass network rather than selecting arbitrary capacitors. The documented 10 kΩ output-load recommendation and nominal 2.83 Vpp single-ended output are important limits, but quiescent current, allowable ripple, and startup behavior are not available in the verified excerpts. Verify those specifications before sizing the supply or adding decoupling, and use measured load transients to identify any audible modulation of the analog output.
Do not assume that any 20-bit stereo codec is a drop-in replacement for the CS4222-BS. Digital codec compatibility depends on the exact pin assignment, audio word format, clock ratios, voltage levels, control interface, and register behavior. The supplied cross-reference results did not verify a pin-compatible alternative, so replacement work requires a side-by-side datasheet review and bench measurement. Also avoid driving the outputs below the documented 10 kΩ load without confirming current and stability limits.
Maklumat Kesediaan
The supplied distributor extract says RoHS status requires verification and does not provide conclusive declarations for RoHS, REACH, lead-free status, halogen-free status, or conflict minerals. AEC-Q100 is not applicable because the product is an audio codec rather than an automotive-qualified device.
