CS4226-BQ 6-Channel Surround Sound Codec | Cirrus Logic
MPN: CS4226-BQ ✓ نشطCS4226-BQ نظرة عامة
An audio codec is a mixed-signal integrated circuit that converts between analog audio signals and digital audio data. Within the semiconductor hierarchy, it is an interface IC and audio codec rather than a conventional amplifier or standalone converter. The CS4226 combines delta-sigma conversion stages, a stereo ADC path, six DAC channels, independent channel-volume functions, and digital control into one device for multichannel audio systems.
The principal feature of the CS4226-BQ is its six-channel DAC architecture with independently selectable volume control for each output. This allows a multichannel system to balance individual speaker or surround channels in software. The device also provides a stereo ADC, an I2C/SPI control interface, and a frequency range suitable for conventional digital audio streams. Its single 5 V operating region simplifies analog and digital supply planning when the rest of the system uses a compatible rail.
The CS4226 family uses delta-sigma conversion techniques rather than the R-2R ladder architecture associated with some high-end audio converters. Delta-sigma converters integrate a noise-shaping and digital-filtering process into the conversion path. The CS4226 datasheet identifies the component as a surround-sound codec, and its control-port listings include SCL/CCLK, SDA/CDOUT, AD1/CDIN, AD0/CS, LRCK, SCLK, and the six DAC data inputs and outputs.
Typical uses include surround-sound decoding in home theater equipment, multichannel amplifier systems, active speaker electronics, AV receivers, and other equipment requiring several independently controlled digital audio outputs. A stereo source can be routed into the codec's digital conversion and processing architecture, while separate digital streams or channels can be assigned to the six DAC outputs. The device can also be paired with external amplifiers when the required output power exceeds the codec's signal-routing role.
Designers should treat the CS4226-BQ as a mixed-signal device and preserve clean separation between analog and digital return currents. The 5 V supply must remain within the specified 4.75 V to 5.25 V range, and unused analog, digital, and control resources should be terminated according to the manufacturer datasheet. PCB layout, grounding, clocking, and supported data-format details must be confirmed from the complete CS4226 documentation before a production design is released.
This page consolidates verified distributor and datasheet information, organizes the commercial and technical selection questions engineers commonly need, and explicitly identifies parameters that require confirmation from the manufacturer documentation. That distinction is important because the public search results verify the core codec identity, package, supply range, temperature range, interface types, and sampling range but do not expose every electrical, timing, pin-level, and lifecycle detail.

التطبيقات النموذجية
CS4226-BQ مناسب لـ 6 التطبيقs: Home-Theater Surround-Sound Processing, Multichannel Active-Speaker System, AV Receiver and Soundbar Platform, Digital Audio Recording Front End, Industrial Audio Control Console, Powered Speaker Network Controller.
Home-Theater Surround-Sound Processing
The CS4226-BQ fits a home-theater codec stage because it combines a stereo ADC, six DAC channels, and independently selectable volume control in one 44-pin TQFP device. A receiver or surround processor can convert incoming analog audio into digital data and distribute controlled analog outputs to external left, center, right, surround, and related channels. Its 4.75 V to 5.25 V supply range supports a conventional 5 V codec rail, while the -40 °C to +85 °C rating provides broad temperature margin. The six-channel architecture reduces the number of separate converters required, although amplifier selection and analog-output loading still depend on the manufacturer specifications.

Multichannel Active-Speaker System
The CS4226-BQ is suitable for an active-speaker control board that requires independently balanced digital-audio channels. Its six DAC outputs and per-channel volume functions allow one codec to receive digital streams, convert them to analog audio, and apply separate level settings before the signals enter power-amplifier modules. The 4 kHz to 50 kHz verified sampling range covers standard digital-audio use cases, while I2C and SPI interfaces provide practical options for system control. Because external amplifiers perform the high-current drive stage, the CS4226-BQ remains a centralized conversion and routing device rather than the speaker-output power stage.
موصى به
AV Receiver and Soundbar Platform
A compact AV receiver or soundbar can use the CS4226-BQ to consolidate multichannel conversion into one mixed-signal device. The stereo ADC supports analog source capture, the six DAC outputs provide surround-channel destinations, and independent volume control enables channel-level calibration through the control interface. Its 10 mm by 10 mm 44-pin TQFP package leaves more board area than six separate converters would require, although careful grounding remains necessary. The 5 V operating range is compatible with common consumer audio power trees, and the industrial temperature rating also permits use in professionally deployed room-audio equipment.

Digital Audio Recording Front End
The CS4226-BQ can serve in an audio-recording front end that needs both stereo analog capture and multiple digital output destinations. Analog inputs pass through the codec's stereo ADC for digital processing, while the six DAC paths provide independently controlled analog outputs for monitoring, mixing, or downstream amplification. The verified 4 kHz to 50 kHz range covers multiple standard sampling rates, and selectable I2C or SPI control supports either configuration-oriented or higher-throughput integration. Interface format, master-clock requirements, and codec latency must be confirmed from the datasheet so the chosen transport and software timing remain compatible.
موصى به
Industrial Audio Control Console
The CS4226-BQ suits industrial audio-control equipment requiring several independently adjusted output channels over a broad temperature interval. Its verified -40 °C to +85 °C range supports environments beyond the -10 °C to +70 °C rating of the related CS4226-KQ variant, while the 4.75 V to 5.25 V supply range supports a regulated 5 V rail. Independent volume control simplifies per-channel calibration in consoles, monitoring stations, or machine-control audio panels. The design must still account for the codec's mixed-signal layout, control-signal timing, analog grounding, and the external power needed by loudspeakers.
موصى به
Powered Speaker Network Controller
The CS4226-BQ can act as the central conversion and control component in a powered speaker network. A controller receives digital audio streams, uses the codec's six-channel DAC architecture to create analog line-level outputs, and applies independent channel volume before those signals reach external amplifiers. The I2C and SPI control options let the controller software configure operating state through a microcontroller or system bus. The integrated 44-pin TQFP arrangement reduces the footprint relative to multiple converters, but each design must verify supported sample formats, clocking, output loading, and bypass behavior against the complete Cirrus Logic documentation.

ملاحظات التصميم
Treat the analog and digital sections as separate return-current domains even though both are housed in one mixed-signal package. Place the codec decoupling capacitors at the corresponding supply pins, keep the I2C or SPI control routing away from sensitive analog inputs, and use the manufacturer's recommended reference and analog-return connections. The verified data does not provide the complete pin map or grounding schematic, so PCB implementation should follow the CS4226 datasheet layout rather than an inferred generic TQFP arrangement.
Design the codec rail for 4.75 V to 5.25 V operation and verify ripple, startup behavior, and the requirements for each analog and digital supply node in the manufacturer documentation. The verified results identify a single nominal 5 V operating region but do not provide separate rail tolerances, current limits, or sequencing rules. A regulated 5 V source with local high-frequency bypassing is therefore a starting point, not a substitute for the complete power-supply recommendations in the CS4226 datasheet.
Do not assume that all similarly suffixed CS4226 orders are interchangeable without checking the ordering table. The verified evidence shows that CS4226-KQ has a narrower -10 °C to +70 °C range, while CS4226-DQ and CS4226-BQZ are listed with the same -40 °C to +85 °C range as CS4226-BQ. Lead-free status, grade codes, marking, and qualification requirements can still differ. Compare the exact orderable code and manufacturer product-selection records before releasing a replacement.
Confirm the supported audio-word format, master-clock relationship, bit clock, latch signal, and supported sampling rate before finalizing the digital audio connection. The verified 4 kHz to 50 kHz range establishes the broad sampling limit, but it does not prove that every format is valid at every rate. Route clocks and data away from analog inputs, maintain return paths under the data lines, and use source-synchronous timing margins from the datasheet rather than assuming interface compatibility from the I2C/SPI label alone.
معلومات الامتثال
