WM8144CCPT Audio Channel IC | Texas Instruments

The Texas Instruments WM8144CCPT is an audio-channel integrated circuit listed by DigiKey Marketplace and Octopart, with the product categorized as an Audio Special Purpose device in the Audio ICs family. The verified distributor information identifies WM8144CCPT as an active part available for sourcing, but the supplied records do not provide a verified package, pin count, electrical ratings, or detailed functional specifications. The searchable part number and category indicate a dedicated audio signal-processing role rather than a general-purpose logic or power component. Engineers should obtain the manufacturer datasheet and confirm the exact land pattern before committing a replacement to an existing PCB. An audio-channel IC is a specialized integrated circuit that handles one or more functions within an audio signal chain, such as conditioning, conversion, channel selection, or control. These devices sit between audio sources and downstream amplifiers, converters, microphones, speakers, or digital audio processors. Their performance requirements commonly include low signal distortion, stable channel behavior, compatible logic levels, and electrical characteristics matched to the intended audio architecture. Because the verified WM8144CCPT records provide only the part identity and broad category, device-specific claims should not be inferred without the original Wolfson Microelectronics or Texas Instruments documentation. The visible sourcing records support three practical points about WM8144CCPT. DigiKey Marketplace labels it as an audio channel from Texas Instruments, Octopart lists it as an integrated circuit for audio special purposes, and Rochester Electronics distribution data reports active production status. The supplied pricing excerpt gives a starting unit price of $4.07 at one-unit quantity and mentions volume discounts at 10, 100, 500, and 1,000 units. Availability language differs among marketplaces, so a purchase decision should use a current authorized-distributor quote and manufacturer inventory confirmation. WM8144CCPT is most relevant to legacy or industrial audio platforms in which the original circuit was designed around this exact device. In such systems, preserving the original device is generally safer than selecting a generic audio IC with similar nominal functionality. Any substitute must be checked for exact package dimensions, lead pitch, exposed-pad requirements, pin assignments, supply voltage, clocking, control interface, analog performance, and lifecycle status. The verified information identifies Rochester Electronics as the source of the distributed WM8144CCPT offer, so procurement documentation should also confirm the original manufacturer and authorized sourcing chain. The key engineering constraint is that the available verified data is incomplete. Mounting type, operating-temperature range, package case, absolute maximum ratings, supply voltage, channel count, resolution, interface type, and pin assignments are not stated in the supplied records. These values must be read from the applicable manufacturer datasheet before schematic capture, footprint selection, or production release. This prevents the mistake of treating a distributor category label as a substitute for full electrical and mechanical documentation. A sound sourcing workflow is to compare the distributor listing, Rochester Electronics product record, and Octopart cross-reference data against the original system documentation. Confirm that the ordered suffix CCPT matches the required package and ordering configuration, then request current stock and traceable shipment details. For repair and redesign programs, also inspect the board assembly records for markings or bill-of-material entries that may reveal the original manufacturer designation. This page consolidates the verified sourcing status, pricing basis, category placement, and data gaps for WM8144CCPT while avoiding unsupported electrical claims. It is intended to support initial part identification and procurement research, not to replace the manufacturer datasheet, reference schematic, or board-level compatibility checklist.

WM8144CPT - 10-Bit CCD Imaging Data Converter | Texas Instruments
WM8144CPT

WM8144CPT - 10-Bit CCD Imaging Data Converter | Texas Instruments

The Texas Instruments WM8144CPT is an integrated 10-bit data-acquisition system for imaging applications, packaged in a 27-pin CPT surface-mount package. It combines the analog signal-conditioning functions required by CCD sensors with a 10-bit ADC and optional pixel-by-pixel image compensation. The supplied source identifies WM8144CPT as an audio-channel IC, while the family description identifies WM8144 as an integrated CCD-imaging data-acquisition system. Those descriptions should be reconciled against the original manufacturer documentation before using the part in a new design. A CCD image sensor is a semiconductor that converts accumulated light into analog charge and transfers that charge through output circuitry in a sequence. Because the resulting signal is weak, noisy, and often offset or gain mismatched, imaging systems require conditioning before digital conversion. An integrated data-acquisition IC reduces discrete circuitry and helps standardize the interface between the sensor output amplifier, analog-to-digital converter, and image-processing electronics. The WM8144 family provides the core functions needed for imaging: CCD-compatible analog signal conditioning, a 10-bit ADC, and optional pixel-by-pixel compensation. Compensation circuitry is used to correct sensor-column offsets, gain variations, dark current, or fixed-pattern effects before pixels are interpreted. The practical benefit is a more compact analog section, but final image quality still depends on sensor characteristics, clocking, grounding, reference quality, and system calibration. The exact suffix CPT denotes the supplied package/orderable variant, but the verified source set does not expose the full pin list, electrical ratings, ADC conversion rate, voltage limits, clock requirements, or operating-temperature limits. Consequently, those values are not inferred here. The 27-page document count reported by a search result is a page count, not proof of the target package pin count, so it is not used to construct a pinout or package drawing. Typical imaging uses include scientific CMOS-compatible signal chains, industrial line-scan cameras, low-light surveillance modules, barcode and document scanners, machine-vision cameras, and embedded optical measurement systems. In each case, the sensor amplifier output must meet the WM8144 input range and sampling requirements. Because those limits are unavailable in the supplied data, a new design should treat them as release-gating requirements and verify them in the original datasheet. Layout is especially important because CCD outputs are high impedance and susceptible to coupling, ground noise, and reference disturbance. Place the device close to the sensor output, keep the analog path compact, isolate clocks from sensitive traces, and return unused inputs according to the verified pin documentation. Use a stable, low-noise reference and suitable bypass capacitors once their required values are confirmed from the manufacturer guidance. This page distinguishes documented WM8144-family functions from unverified target-variant specifications, lists the supplied sourcing records, and avoids fabricating pin assignments, ratings, lifecycle claims, stock levels, or prices. Engineers should download and review the original WM8144 documentation before layout release, schematic sign-off, or production procurement.

WM8152SCDS/V

WM8152SCDS/V - 16-Bit Single-Channel CIS/CCD AFE | Cirrus Logic

The Cirrus Logic WM8152SCDS/V is a single-channel 16-bit analog front end and digitizer for CCD sensors and contact image sensors, operating at pixel sample rates up to 12 MSPS in a 20-lead SSOP package. It includes a 5 V analog supply requirement, digital supply support from 2.97 V to 3.63 V or 5 V, and a listed power dissipation of 225 mW. An analog front end, or AFE, is the interface between a sensitive image sensor and the digital signal-processing system. It conditions the small sensor signal, controls timing and correlated double sampling, performs analog-to-digital conversion, and presents digitized image data to an external processor. The WM8152SCDS/V belongs to the broader CMOS image-sensor interface and data-conversion hierarchy, combining sensor analog conditioning with a 16-bit digitizer. The WM8152SCDS/V is identified as a single-channel device with 16-bit resolution and a maximum pixel rate of 12 MSPS. The manufacturer describes it as a CIS/CCD AFE with 4-bit wide output, making it suitable for scanners, imaging modules, and compact image-processing systems. Its 20-SSOP package provides a conventional surface-mount footprint for equipment where board area and production compatibility are important. The analog supply is specified at 5 V, while the digital interface can operate from either 2.97 V to 3.63 V or 5 V. This flexibility allows the digitizer to operate with either 3.3 V or 5 V digital system logic when the external interface, timing, and signal-integrity requirements are satisfied. The device is designed for CMOS image-sensor signal chains rather than general-purpose audio or instrumentation conversion. Typical uses include contact image sensors in scanners, CCD-based imaging assemblies, document-capture systems, and other pixel-oriented imaging products. In these applications, the AFE is placed close to the image sensor so that the weak analog signal is conditioned and digitized before long PCB traces introduce additional noise or distortion. A key design consideration is separating the analog and digital return paths while keeping the sensor interface traces short. The power-supply network should provide low-impedance connections for both the 5 V analog rail and the selected digital rail, and the input and output routing should follow the manufacturer’s pin and layout guidance. The 225 mW listed power value should also be checked against the system’s thermal envelope during sustained operation. This product record combines the manufacturer-described AFE function, the listed electrical and packaging characteristics, source links for documentation and purchasing, and practical application guidance for CIS and CCD imaging designs.

WM8196SCDS/V - 16-Bit 12 MSPS 3-Channel AFE | Cirrus Logic
WM8196SCDS/V

WM8196SCDS/V - 16-Bit 12 MSPS 3-Channel AFE | Cirrus Logic

Cirrus Logic WM8196SCDS/V is a 16-bit, three-channel analog front end and digitizer for CCD sensors and contact image sensors, operating at pixel sample rates up to 12 MSPS in a 28-pin SSOP package. The device combines analog signal conditioning with high-speed digitization. An analog front end is an interface between a sensitive imaging sensor and an electronic system. It conditions the small analog signals produced by CCD or CIS pixels before conversion into digital data. In the broader device hierarchy, an AFE precedes an ADC, which forms part of a data-conversion system and ultimately supports image acquisition, scanning, inspection, and machine-vision processing. The WM8196SCDS/V provides three analog processing channels, each incorporating reset-level clamping, correlated double sampling, and programmable gain and offset adjustment. Three internal multiplexers support single-channel processing, while a shared high-speed ADC time-multiplexes the channel outputs. According to the manufacturer datasheet, the digital output uses an 8-bit plus 8-bit data organization. The device supports a 12 MSPS pixel sampling rate and delivers 16-bit digitized image data, making it appropriate for CCD and CIS imaging systems that require more scan-line throughput than a general-purpose low-speed ADC provides. Its analog supply is 5 V, while the digital interface can operate from 2.97 V to 3.63 V or 5 V, allowing integration with both 3.3 V and 5 V digital systems. Typical uses include document scanners, flatbed scanners, contact-image-sensor scanners, industrial inspection equipment, and compact imaging modules. Each analog channel can apply calibrated gain and offset to compensate for pixel and sensor variation before the multiplexed ADC performs conversion. The main design consideration is the relationship among sensor timing, analog signal conditioning, output data capture, and clocking. The three channels and their multiplexers must be configured for the intended sensor arrangement, and the digital interface must match the host processor voltage and data-capture method. Power and grounding also require care because sensor signals pass through high-gain analog stages before digitization. This page consolidates the manufacturer electrical information, package details, application guidance, comparison parameters, and practical design notes into one engineering reference. It also distinguishes verified drop-in alternatives from packaging variants that do not constitute meaningful component substitutions.

WM8199SCDS/V - 3-Channel 16-Bit 20MSPS AFE | Cirrus Logic
WM8199SCDS/V

WM8199SCDS/V - 3-Channel 16-Bit 20MSPS AFE | Cirrus Logic

Cirrus Logic WM8199SCDS/V is a three-channel, 16-bit analog front end and digitizer capable of processing CCD and contact image sensor outputs at pixel sample rates up to 20MSPS. The device is supplied in a 28-pin SSOP package and is listed with a power dissipation of 358 mW. An analog front end, or AFE, is an interface circuit that conditions analog sensor signals before digitization. Its role in the signal chain is to prepare incoming CCD or contact image sensor voltages for accurate conversion by an ADC. Within the broader hierarchy, an AFE is a data-acquisition IC, an interface IC, and ultimately a semiconductor designed to bridge specialized analog sensors with digital image-processing systems. The WM8199SCDS/V provides three signal-processing channels, 16-bit digitization, and operation to 20MSPS. These headline specifications make it suitable for multichannel scanner, contact image sensor, and industrial imaging systems that require synchronized conversion of narrow pixel signals. Its three-channel architecture can reduce the number of separate front-end devices needed when a sensor exposes multiple outputs. The 20MSPS maximum sample rate establishes the upper conversion-speed limit for each supported channel. It determines how rapidly successive pixel positions can be processed and is important when matching the AFE to sensor timing, clocking, and downstream image throughput. The 16-bit digital output provides substantially greater numerical resolution than lower-bit converters, supporting precise capture of gradual signal changes. The WM8199SCDS/V is specifically associated with CCD sensors and contact image sensors rather than general-purpose audio or instrumentation front ends. Typical application areas include document scanners, flatbed scanners, contact image sensor modules, inspection equipment, and other imaging systems that require three analog inputs, 16-bit conversion, and a maximum sampling rate of 20MSPS. System design must preserve the relationship between sensor pixel rate, analog input bandwidth, clocking, and the downstream image processor. The AFE should be placed close to the sensor outputs, with a low-noise and appropriately terminated reference arrangement. Power distribution and grounding require care because converter performance is influenced by supply noise and signal return paths. This product page combines the WM8199SCDS/V technical identity, package information, application guidance, sourcing details, and cross-reference analysis in a format intended to accelerate component selection and board-level implementation. It also emphasizes the distinction between a true pin-compatible replacement and a merely similar imaging converter.

WM8213SCDS/V - 16-Bit 3-Channel 24MSPS AFE | Cirrus Logic
WM8213SCDS/V

WM8213SCDS/V - 16-Bit 3-Channel 24MSPS AFE | Cirrus Logic

Cirrus Logic WM8213SCDS/V is a 3-channel, 16-bit analog front end and digitizer designed for CCD sensors and contact image sensors, with a maximum sampling rate of 24 MSPS and power consumption of 350 mW. The device is supplied in a 28-pin SSOP package measuring 5.30 mm in body width. An analog front end, or AFE, converts weak sensor signals into digital data while performing the analog conditioning needed before conversion. The AFE sits between the optical sensor and the digital system, performing sensor-level clamping, correlated double sampling, programmable gain and offset adjustment, and channel multiplexing. In the hierarchy of electronic components, the WM8213SCDS/V is an AFE, ADC, signal-chain IC, and semiconductor intended for high-speed imaging systems. The WM8213SCDS/V includes three independent analog signal-processing channels. Each channel provides reset-level clamping, correlated double sampling, and adjustable gain and offset functions. Three analog multiplexers support channel selection, while the processed signals are time-multiplexed into one high-speed 16-bit ADC. This architecture reduces the number of separate converters required in a multichannel imaging system and concentrates the digitized output into a common serial interface. Its 24 MSPS pixel sampling capability is suitable for CCD and CIS imaging systems that require high-speed transfer of image data. The 16-bit ADC resolution provides 65,536 quantization levels, while the 350 mW device rating indicates a relatively low power demand for a three-channel high-resolution imaging front end. Analog and digital operating supplies are both specified from 2.97 V to 3.63 V, supporting a 3.3 V system environment. Typical uses include line-scan cameras, contact image sensors, document scanners, barcode and inspection equipment, and other optical acquisition systems in which multiple sensor outputs require correlated sampling and shared digitization. The three-channel architecture is particularly useful when the imaging system must process more than one sensor signal without deploying three complete standalone ADC channels. PCB implementation should preserve short, controlled analog paths between the sensor outputs and the corresponding AFE inputs. Decoupling capacitors should be placed close to the supply pins, while the serial digital outputs require a compact, impedance-controlled layout away from the analog inputs. The 28-pin SSOP footprint also requires adequate board width and careful lead-clearance planning during inspection or assembly. This product summary combines the WM8213SCDS/V electrical ratings, architecture, package characteristics, sourcing information, and design guidance into one engineering reference. It also distinguishes verified operating facts from parameters that must be confirmed in the manufacturer datasheet before a new sensor board is released.

WM8214SCDS/V - 16-Bit 3-Channel 40MSPS AFE | Cirrus Logic
WM8214SCDS/V

WM8214SCDS/V - 16-Bit 3-Channel 40MSPS AFE | Cirrus Logic

The Cirrus Logic WM8214SCDS/V is a 16-bit, three-channel analogue front end (AFE) and CCD digitiser that converts analogue sensor outputs at pixel sample rates up to 40 MSPS, operated from 2.97 V to 3.63 V on both the analog and digital rails, and dissipating 390 mW. It is packaged in a 28-SSOP surface-mount package with a 0.209 in (5.30 mm) body width. The /V suffix identifies the lead-free ordering option of the original Wolfson Microelectronics WM8214SCDS device. An analogue front end is the signal-conditioning and conversion block that sits between an imaging sensor and a digital processor. It takes the weak, noisy analogue charge or voltage signal produced by a CCD or CIS sensor, applies gain, offset and timing control, and then performs the analogue-to-digital conversion that turns the sensor waveform into numeric pixel data. In the product hierarchy, an AFE is a data-acquisition IC, which is a subclass of mixed-signal and interface semiconductors used in imaging, instrumentation and industrial automation systems. Key features of the WM8214SCDS/V include 16-bit conversion resolution, three parallel channels for multi-phase sensor timing, a maximum pixel sampling rate of 40 MSPS, a single 2.97 V to 3.63 V supply range shared by the analog and digital sections, and a compact 390 mW power dissipation in an industry-standard 28-SSOP footprint. The combination of three channels and 40 MSPS throughput allows one device to digitise the output of a three-output CCD or CIS sensor without external multiplexers or separate converter ICs. The WM8214SCDS/V integrates the full imaging signal chain into a single package: analog conditioning, sampling, conversion and digital output in one device. Separate analog and digital supply pins allow a system architect to partition noisy digital return currents from the sensitive analog reference and signal planes, which is the standard technique used to reach the noise floor required for 16-bit resolution. Because the converter runs directly from the sensor clock, no external sample-and-hold stage or external ADC is required between the CCD output amplifiers and the digital back-end. Typical applications include flatbed contact image sensor (CIS) scanner signal chains, line-scan CCD machine vision modules, copier and multi-function printer imaging engines, industrial inspection and optical metrology equipment, portable and handheld document scanners, and dedicated barcode or document imaging modules. The 40 MSPS sampling ceiling covers the pixel rates of mainstream office and industrial CIS strips, while the three-channel architecture matches typical three-phase or multi-output CCD timing schemes. A key design consideration is supply partitioning and decoupling. Because the analog and digital sections use separate supply pins within the same package, route them on distinct planes and place the analog bypass capacitors directly at the analog supply pins to avoid shared-impedance coupling of switching noise into the signal path. The 28-SSOP body also limits total copper area, so keep the analog ground return path short and directly beneath the device. This page consolidates device specifications, supply voltage and power limits, package and ordering information, drop-in alternatives from the same Cirrus Logic imaging AFE family, and practical PCB design notes into a single reference for engineers evaluating the WM8214SCDS/V for CCD and CIS imaging designs.

WM8215CSEFL - 3-Channel 10-Bit 60MSPS CCD/CIS AFE | Cirrus Logic
WM8215CSEFL

WM8215CSEFL - 3-Channel 10-Bit 60MSPS CCD/CIS AFE | Cirrus Logic

The Cirrus Logic WM8215CSEFL is a 3-channel, 10-bit analog front end (AFE) for CCD and CIS image sensors, sampling at up to 60 MSPS per channel while consuming approximately 400 mW of power, housed in a 32-pin QFN (5x5 mm) package. An analog front end for image digitisation is the circuit block that sits directly between a photosensitive sensor and the digital image processor. CCD and CIS sensors output small, correlated-double-sampling (CDS) dependent analog charges that must be conditioned, clamped, sampled and converted to digital words with matched timing across multiple channels. The AFE therefore combines programmable gain, offset correction, black-level clamping, CDS sampling and a multi-channel ADC pipeline in one integrated circuit, forming part of the broader signal-chain hierarchy: sensor -> AFE -> ADC -> image processor -> system. Key features of the WM8215 include three independent 10-bit conversion channels rated at 60 MSPS, a total power dissipation of around 400 mW, and support for both CCD and CIS sensor architectures. The part is fabricated in CMOS, which keeps quiescent consumption low and supports dense multi-channel integration. Wolfson Microelectronics, the original designer, was acquired by Cirrus Logic, so datasheets may appear under either brand name. Architecturally, the WM8215 uses a pipelined 10-bit ADC per channel preceded by input conditioning stages, allowing each colour channel of a linear sensor array to be digitised simultaneously. Simultaneous sampling eliminates inter-channel skew artefacts such as colour fringing in line-scan imaging, which sequential multiplexed converters cannot avoid. Typical applications include document scanners and multi-function printers with CIS arrays, industrial line-scan inspection cameras, machine-vision systems for surface inspection, and scientific or medical linear CCD readout chains where three matched channels map naturally to RGB or multi-tap sensor outputs. A key design consideration is signal integrity: keep the analog input traces short, guard them with ground, and follow the manufacturer datasheet for reference-decoupling and CDS timing, since jitter or noise on the sampling clock converts directly into image fixed-pattern noise. Thermal dissipation of 400 mW should be managed with the QFN exposed pad soldered to a ground pour. This page synthesises distributor availability, package and application data, and practical design notes not found in the manufacturer datasheet, and it is verified and refreshed against distributor listings.

WM8224CSEFL

WM8224CSEFL - 60 MSPS 3-Channel AFE | Cirrus Logic

Cirrus Logic WM8224CSEFL is a three-channel analog front end (AFE) for high-speed digital video and audio conversion, featuring programmable resolution of 8, 10, 12, or 16 bits and operation up to 60 MSPS. The device uses a 32-VFQFN package with an exposed pad and operates from 2.97 V to 3.63 V for both analog and digital supplies. Its typical power consumption is 360 mW, making it suitable for compact, multichannel signal-chain designs requiring controlled ADC front-end performance. An analog front end is an integrated signal-conditioning and conversion stage that sits between analog sensors or video inputs and a digital processor. It combines analog input conditioning, programmable gain, sampling, filtering, and conversion functions in one device. The WM8224 belongs to the broader ADC and data-converter hierarchy, with the AFE adding channel multiplexing and signal-conditioning functions that are normally implemented as separate components. The WM8224CSEFL provides three independently addressed input channels and supports multiple-device operation, allowing additional AFEs to be coordinated in larger systems. Programmable automatic black-level calibration supports imaging and video applications where the black reference must track component and signal-chain variation. Resolution can be configured across 8, 10, 12, and 16 bits, giving designers flexibility to balance conversion detail, data rate, and power requirements. Its analog and digital supply ranges of 2.97 V to 3.63 V align with common 3.3 V system rails. The 32-VFQFN, 5 x 5 mm package includes an exposed thermal pad for improved heat dissipation, but the layout must provide adequate copper area and a low-impedance ground connection. The AFE's 60 MSPS capability is suitable for video capture, image processing, surveillance, communications, and other multichannel sampling systems. Applications include three-channel video sensor interfacing, industrial imaging, document scanners, machine vision, surveillance cameras, and multichannel signal acquisition. For each design, confirm the selected operating mode, channel assignment, clocking arrangement, and black-level calibration strategy against the manufacturer datasheet. The input network, decoupling capacitors, analog ground, digital return paths, and exposed-pad thermal design are especially important in high-speed layouts. This page consolidates the WM8224CSEFL device identity, key electrical and package characteristics, sourcing information, design guidance, and verified drop-in alternatives. It also distinguishes the exact MPN from family-level references so procurement and PCB decisions are based on a traceable device configuration.

WM8232GEFL/V - 16-Bit 3-Channel AFE | Cirrus Logic
WM8232GEFL/V

WM8232GEFL/V - 16-Bit 3-Channel AFE | Cirrus Logic

Cirrus Logic WM8232GEFL/V is a three-channel, 16-bit analog front end operating at up to 70 MSPS, with sensor timing generation and selectable LVDS or CMOS data outputs in a 56-QFN 8 x 8 mm package. Its analog and digital supply ranges are both 2.97 V to 3.63 V, supporting compact, low-voltage imaging systems. An analog front end, or AFE, combines analog signal conditioning and data conversion at the input of a digital processing system. In the product hierarchy, the WM8232GEFL/V belongs to the ADC/DAC class of integrated circuits and converts weak or noisy sensor signals into digital data. Its three processing channels reduce the need for separate amplifiers, clamp circuits, sampling circuits, gain stages, and offset-adjust networks. Each channel includes reset-level clamping, correlated double sampling or sample-and-hold, programmable gain, automatic gain control, and offset adjustment. These functions improve the usable dynamic range of the incoming analog signal before digitization. The 16-bit conversion resolution preserves fine signal detail, while the integrated AGC reduces the workload required from the downstream image processor. Sensor timing generation coordinates frame acquisition, while the LVDS and CMOS output options provide flexibility in board architecture. LVDS is useful when a design requires a high-speed differential link with good noise immunity; CMOS offers a simpler single-ended interface where board-level signal integrity is easier to manage. Both output configurations support 3.3 V-class digital systems represented by the 2.97 V to 3.63 V supply range. Typical uses include industrial image sensors, machine-vision cameras, medical imaging equipment, surveillance cameras, barcode scanners, and embedded optical measurement systems. Three integrated channels are particularly useful for color imaging, stereo sensing, or multichannel sensor configurations where synchronized acquisition and consistent channel calibration are important. The principal design consideration is interface implementation. Confirm the selected LVDS or CMOS output mode, external clocking requirements, sensor timing, and exposed-pad thermal arrangement against the manufacturer pin and layout documentation. Power and ground distribution must keep analog and return currents controlled because converter clocking and data-output switching can introduce noise into the sampled signal. This product overview consolidates the channel architecture, conversion performance, supply limits, output options, and application guidance into an engineering-focused reference. It also highlights the practical checks needed to evaluate the WM8232GEFL/V in a new sensor-processing board.

WM8233GEFL/V

WM8233GEFL/V - 16-Bit 6-Channel 70 MSPS AFE | Cirrus Logic

The Cirrus Logic WM8233GEFL/V is a six-channel, 16-bit analog front end and digitizer designed for high-speed CCD and contact image sensor signal chains. It supports pixel sampling rates up to 22.5 MSPS per channel, while its distributor descriptions identify the device family as a 70 MSPS six-channel AFE. The component is packaged in a 56-pin VFQFN package measuring 8 mm by 8 mm with an exposed pad. An analog front end, or AFE, is an interface IC that conditions, samples, and converts sensor signals into digital data. The AFE category sits between the sensor and the digital processing system: CCD or CIS outputs enter the AFE, programmable analog processing prepares those signals, and the resulting high-speed data is delivered to a processor or image pipeline. WM8233 belongs to this broader class of high-speed mixed-signal semiconductor and sensor-interface IC. The WM8233 provides six analog signal-processing channels, each incorporating reset-level clamping, correlated double sampling, sample-and-hold circuitry, and programmable gain according to the manufacturer datasheet. Its 16-bit conversion resolution preserves fine amplitude detail in imaging systems. Programmable operating modes, sensor timing generation, and selectable CMOS or LVDS data outputs allow the interface to be adapted to different sensor and back-end requirements. WM8233GEFL/V operates from a 2.97 V to 3.63 V analog supply range. The manufacturer documentation also describes a separate digital supply, supporting independent control of analog and digital power domains. This separation can help designers isolate sensitive analog processing from digital-interface noise while maintaining a common 56-pin package and compact 8 mm by 8 mm footprint. Typical applications include linear CCD scanners, contact image sensors, document imaging systems, industrial inspection equipment, and other multichannel imaging platforms. Six integrated channels are particularly useful where multiple sensor outputs must be sampled coherently. The timing-generation and data-output functions reduce the external control burden associated with synchronizing sensor transfer, sampling, and digital readout. Designers should place input, reference, and digital-output connections for controlled impedance, maintain the analog and digital return paths separately, and use the exposed thermal pad with an appropriate PCB ground and thermal layout. The pin and exposed-pad connections should follow the manufacturer pin-description table and recommended land pattern exactly. Because this device is listed as NRND, new designs should confirm lifecycle and sourcing requirements before committing to production. This product page consolidates the verified channel count, resolution, sampling-rate descriptions, supply range, package, lifecycle status, and sourcing information. It also distinguishes electrically similar Cirrus Logic devices from verified drop-in replacements and provides practical guidance for evaluating the WM8233 in CCD and CIS imaging systems.

It accepts analog and digital supply voltages from 2.97 V to 3.63 V and is packaged in a 56-VFQFN exposed-pad package measuring 7 mm by 7 mm. An analog front end is an integrated signal-processing IC positioned between an imaging sensor and a digital image processor. Within the broader integrated-circuit hierarchy, an AFE is a data-acquisition component combining analog conditioning, sampling, and digital conversion. The WM8235 performs nine parallel sensor signal paths, allowing a scanner, copier, or imaging module to digitize multiple outputs while maintaining coordinated timing. Each of the nine analog channels includes reset-level clamping, correlated double sampling or sample-and-hold, programmable gain, automatic gain control, and offset adjustment. These functions allow the WM8235GEFL/V to condition sensor outputs before conversion. The device supports a 16-bit conversion resolution and can process sensor signals at pixel sample rates up to 23 MSPS per channel, according to the manufacturer datasheet. The WM8235 family also generates the sensor timing signals required to transfer charge and reset information from the imaging array. Programmable timing, channel-level signal conditioning, and integrated digitization reduce the number of external analog components needed around a sensor. Output data can be delivered through LVDS or CMOS interfaces, providing configuration flexibility for different imaging systems and downstream processors. Typical applications include flat-panel scanners, document copiers, multifunction printers, contact image scanners, and other CCD- or CIS-based imaging equipment. Its 9-channel architecture is particularly useful when an imaging module presents several sensor outputs that must be sampled consistently. The 3.3 V operating range also simplifies integration with contemporary 3.3 V digital systems. PCB design should provide a low-impedance analog and digital ground structure, place decoupling capacitors close to the supply pins, and use controlled-impedance routing for high-speed CMOS or LVDS outputs. The exposed pad requires a thermal and electrical land pattern specified by the manufacturer datasheet; it must not be treated as an unused mechanical feature. This page combines the WM8235GEFL/V device specifications, verified manufacturer and distributor listings, package information, application guidance, and engineering design notes. It also distinguishes documented device functions from sourcing questions so engineers can evaluate the AFE quickly and consult the manufacturer datasheet for implementation details.

WM8255SEFL

WM8255SEFL - 16-Bit 12 MSPS Single-Channel CCD/CIS AFE

Cirrus Logic WM8255SEFL is a single-channel 16-bit analog front end and digitizer for CCD and contact image sensor (CIS) imaging systems, processing analog pixel signals at rates up to 12 MSPS. The device is supplied in a 28-QFN 4 x 4 mm package and is identified by distributor listings as a 1-channel AFE with integrated signal processing for image sensors. An analog front end (AFE) is an interface circuit between an imaging sensor and the digital signal-processing system. It conditions the sensor output, removes reset or pedestal-related offsets, applies gain and offset adjustments, performs correlated double sampling where supported, and converts the conditioned analog waveform into digital data. In the broader IC hierarchy, the WM8255SEFL belongs to the ADC/DAC and interface-processing family, specifically the imaging analog front-end category. The WM8255 includes reset-level clamping, correlated double sampling, programmable gain and offset adjustment functions, and a complete signal-processing channel for CCD or CIS signals. Its 16-bit conversion resolution supports precise capture of sensor output levels, while the 12 MSPS pixel sample rate supports demanding scanner, document-imaging, machine-vision, and optical-registration workflows. The single-channel architecture is appropriate where the imaging system does not require simultaneous processing of multiple sensor outputs. The 28-QFN package is designed for compact surface-mount PCB layouts, but the QFN construction requires careful thermal-pad assembly and land-pattern compliance. Signal integrity is central because the device handles small analog sensor signals and clock-related timing paths. Designers should preserve the manufacturer-recommended decoupling, analog and digital grounding, clock routing, and sensor-interface layout patterns described by the WM8255 documentation. Typical uses include CCD-based scanners, CIS scanners, document imaging, industrial inspection, optical measurement, and other embedded imaging products. The part may be considered in new designs when the system specifically requires a CCD/CIS-oriented single-channel AFE and can be matched to its electrical and timing requirements. The manufacturer product page identifies WM8255 as discontinued, so procurement and design decisions should account for lifecycle status rather than assuming long-term availability. Before schematic capture, verify the complete device pinout, supported operating modes, supply requirements, clocking limits, and application-specific sensor interface against the manufacturer documentation. Because public search results provide the main functional and package facts but do not expose every timing, voltage, or environmental parameter, missing values are identified explicitly rather than guessed. This page consolidates the verified WM8255 identification, single-channel CCD/CIS AFE function, 16-bit resolution, 12 MSPS throughput, 28-QFN package, source links, lifecycle notice, and practical design guidance into a procurement-oriented technical summary.

WM8259SCDS/V - 16-Bit CCD/CIS AFE | Cirrus Logic

The Cirrus Logic WM8259SCDS/V is a single-channel, 16-bit analog front end for CCD and CMOS image sensors, operating at up to 3 MSPS with 132 mW power consumption in a 20-pin SSOP package. It combines analog image-signal processing with a 3.3 V ADC output stage for compact electronic imaging systems. An analog front end, or AFE, is a semiconductor interface between an imaging sensor and the downstream digital signal-processing or storage system. Its role in the imaging hierarchy is sensor interface, analog signal conditioning, and data conversion. The WM8259SCDS/V belongs to the broader CCD/CIS ADC and ADC/DAC product categories, while the 16-bit ADC and four-bit-wide parallel output implement the digital sampling interface. The device provides two selectable video-input pins and one complete analog processing channel. According to the manufacturer datasheet, that channel includes reset-level clamping, correlated double sampling, programmable gain, and offset adjustment. Internal multiplexers permit rapid switching between offset and gain settings during line-by-line color processing. These functions reduce the amount of external analog conditioning normally required around a CCD or CIS sensor. Its 16-bit conversion resolution and 3 MSPS sampling rate support imaging designs that require more precision than an 8-bit or 12-bit sensor interface. The 132 mW operating-power figure is suitable for compact camera, scanner, and machine-vision systems where signal-chain power can affect thermal design. The 3.3 V supply and four-bit-wide digital output organize the device around contemporary CMOS image-sensor interfaces. Typical applications include CCD-based scanners, CMOS image-sensor modules, color-line imaging systems, surveillance cameras, barcode readers, industrial vision equipment, and embedded imaging controllers. In each case, the selectable inputs, analog clamp, correlated double sampling, gain controls, and offset controls help implement a consistent readout chain close to the image sensor. PCB design should preserve the manufacturer’s recommended input, output, and bypass-capacitor placement because the AFE combines high-speed sampling with sensitive analog processing. Keep sensor traces short, provide a low-impedance return path, and follow the pin-configuration and layout guidance in the datasheet. Verify that downstream logic matches the device’s four-bit-wide output and required clocking arrangement. This product page combines the manufacturer-function description, distributor package and speed information, a verified same-package cross-reference, and practical interface guidance. It is intended to help engineers identify the correct imaging AFE, distinguish the available order code, plan board-level integration, and evaluate where this single-channel 16-bit CCD/CIS front end fits.

It provides a 24-bit audio interface using SLIMbus and is identified by distributor data as integrating 6 ADC and 8 DAC channels. An audio codec is an integrated circuit that converts analog microphone or line-level signals into digital audio data while converting digital playback streams back into analog audio outputs. The WM8281 belongs to the broader smart-codec hierarchy, combining a conventional audio codec with embedded DSP functions. This integration allows a host processor to handle system control while dedicated hardware executes noise reduction, echo cancellation, speech enhancement, and advanced media processing. Key product features include programmable DSP cores supporting multi-microphone wideband noise reduction, acoustic echo cancellation, speech enhancement, and advanced media enhancement. The 24-bit SLIMbus interface supports connected audio systems, while the integrated ADC and DAC channels reduce the external analog circuitry required for voice and multimedia products. Its low-power design is intended to benefit always-listening and portable audio equipment where continuous processing must remain energy efficient. The WM8281 architecture separates audio conversion from programmable signal processing. SLIMbus provides a shared serial link between the codec and a host or audio processor, while the DSP feature set performs real-time voice enhancement. This combination can shorten signal paths and reduce system complexity in applications requiring microphone capture, voice processing, and audio playback through a common codec package. Typical uses include smartphone and tablet voice-calling systems, headset and wearable audio platforms, smart speakers, teleconferencing equipment, voice-user-interface products, and connected consumer devices. Cirrus Logic markets the device as a low-power smart codec with echo cancellation, making it especially relevant to designs handling near-field or far-field speech where acoustic feedback and ambient noise reduce intelligibility. Designers should treat the 138-ball wafer-level chip-scale package as a layout-intensive component and follow the manufacturer's recommended land pattern, exposed-pad, power, ground, and high-speed routing guidance. The analog and digital power domains, microphone inputs, codec outputs, and SLIMbus signals must be planned together because power sequencing, decoupling, and acoustic layout can materially affect performance.

WM8350GEB/V 12-Bit Audio Codec | Cirrus Logic | Power Management
WM8350GEB/V

WM8350GEB/V 12-Bit Audio Codec | Cirrus Logic | Power Management

Cirrus Logic WM8350GEB/V is a 12-bit stereo audio interface with integrated power management, operating at 48 kHz and supplied in a 129-BGA package measuring 7 x 7 mm. The device combines two ADC and two DAC channels, according to the verified distributor and cross-reference records, making it suitable for compact audio subsystems that need conversion and regulated power support in one package. Its BGA construction supports dense PCB layouts but requires careful ball-layout inspection, assembly-process control, and thermal verification. An audio codec is a mixed-signal semiconductor that converts digital audio samples into analog signals and analog sound signals into digital data. A stereo codec therefore normally handles left and right playback and recording paths. As an integrated circuit combining audio conversion with power management, the WM8350GEB/V belongs to the broader semiconductor and audio-interface hierarchy rather than being a simple analog amplifier or passive audio component. The verified product information identifies the WM8350GEB/V as a 12-bit audio interface operating at 48 kHz. Its 129-BGA, 7 x 7 mm package is a principal selection constraint because pin-compatible alternatives must reproduce the same ball layout, exposed features, and board-level connectivity. The listed package also requires land-pattern and assembly inspection that cannot be completed from a distributor category listing alone. Detailed electrical limits, clock requirements, analog performance, power-rail values, and ball functions must be confirmed in the manufacturer datasheet before schematic or PCB release. The integrated power-management function can simplify the architecture of portable and embedded audio products by placing conversion and rail support in one device. This integration may reduce the number of external supporting components when the application uses the complete WM8350 audio subsystem. The tradeoff is that its 129-ball package is less straightforward to hand-solder and more dependent on advanced assembly capability than a leaded or small-outline package. Designers should also validate startup sequencing, analog grounding, clocking, and codec-to-host interface timing against the intended system architecture. Typical uses include portable media devices, smart displays, connected audio products, communication terminals, and embedded systems requiring stereo recording and playback. In these applications, the 48 kHz sampling rate supports conventional digital-audio workflows, while the 12-bit resolution defines the converter word length represented by the verified listing. System-level audio quality still depends on microphone conditioning, amplifier selection, clock jitter, analog layout, grounding, and power-supply implementation; the codec alone does not determine the final acoustic performance. Before design-in, engineers should obtain the official WM8350 datasheet and verify the complete 129-ball pin map, recommended decoupling, supported clock modes, host interface, analog input and output limits, and absolute maximum ratings. The verified distributor record labels the part as an audio interface and 12-bit codec, but it does not provide those implementation details. PCB designers should use the manufacturer land pattern rather than deriving it from package dimensions, and assemblers should confirm whether the selected BGA assembly process supports the device's ball pitch and thermal requirements. This page consolidates verified distributor identification, package constraints, cross-reference evidence, procurement questions, and application guidance that a basic catalog result does not provide. It also distinguishes verified facts from parameters requiring datasheet confirmation, helping engineers decide whether the WM8350GEB/V fits their PCB before committing to a 129-BGA design.

The verified specifications identify a stereo DAC, 24-bit resolution, 192kHz operation, DSP and I2S interfaces, analog and digital supply sources, a 2.7V to 5.5V supply range, and a -40°C to 85°C operating-temperature range. The 1.7Vrms line driver is the key analog-output feature listed by the datasheet source. The 14-SOIC package supports conventional surface-mount PCB assembly while exposing the digital control, power, and analog connections required by the converter. Because the available verified data does not include the complete electrical timing table, pin names, pinout drawing, digital input logic levels, output distortion, dynamic range, channel separation, or recommended application circuit values, those parameters are marked as data needed rather than inferred.

Typical application domains include consumer audio equipment, compact digital audio systems, powered speakers, sound-bar signal paths, computer audio accessories, and legacy high-resolution playback designs. The I2S interface can connect to a suitable digital audio controller when its clocking and framing requirements match the WM8501CGED. The DSP interface provides an additional digital control path for supported audio-processing configurations, but software and register compatibility must be verified before replacement. The main design consideration is power and signal integrity.

WM8520H9GED - Stereo 2Vrms Audio DAC | Cirrus Logic

Cirrus Logic WM8520H9GED is a stereo audio digital-to-analog converter IC with 2 Vrms output capability, supplied in an SOIC package. The device belongs to the digital-to-analog converter class within the broader audio converter and signal-conversion IC hierarchy. Its primary function is converting digital audio information into left and right analog output signals for downstream audio amplification, reproduction, or measurement equipment. An audio DAC is a mixed-signal semiconductor that accepts digital audio data and reconstructs a continuous analog voltage waveform. In a complete audio chain, it follows the digital source and signal-processing stages and precedes an analog output amplifier, speaker driver, or line-level input. The WM8520H9GED’s stereo architecture supports dual-channel signal generation, while its specified 2 Vrms output provides a useful reference for designing the output-network and downstream amplification requirements. The principal documented feature is 2 Vrms stereo output. This makes the converter applicable to consumer audio equipment, digital audio sources, compact stereo systems, and test setups that require balanced left and right signal paths. The SOIC package supports conventional surface-mount PCB assembly and is appropriate for designs that do not require the smaller dimensions of a compact chip-scale package. Board layout must preserve clean analog routing around the converter output circuitry. WM8520H9GED is identified as an audio D/A converter IC and is listed under the Cirrus Logic product name. The “WM” family designation and full suffix identify the specific orderable device and its package-related ordering code. Designers should use the manufacturer datasheet pin description table, electrical characteristics, and recommended application circuit when assigning signals, selecting external components, and confirming interface compatibility with the surrounding digital audio system. Typical uses include digital music players, powered stereo speakers, multimedia equipment, compact home-audio systems, and audio test and measurement products. In each case, the converter can generate separate left and right analog outputs for an amplifier stage. The 2 Vrms specification should be matched to the intended load, output coupling method, gain structure, and protection requirements rather than treated as a universal output-current rating. The primary design consideration is separating sensitive analog output routing from digital interface and clock signals. Keep output traces short, use a stable reference and qualified decoupling network, and follow the manufacturer’s reference layout to minimize conversion-related distortion or crosstalk. Confirm that the surrounding amplifier can accept the converter’s analog output range and signal level. This product page combines the confirmed stereo DAC classification, 2 Vrms output capability, SOIC package information, sourcing guidance, application context, and drop-in replacement research. It also distinguishes a genuine pin-compatible replacement from parts that are merely functionally similar, helping engineers make a safer PCB-level sourcing decision.

It combines an integral charge pump, a DC servo, an I2S audio interface, and a hardware control interface in one compact low-power audio converter. A digital-to-analog converter, or DAC, is an integrated circuit that converts digital audio samples into a continuous analog voltage. The WM8524 belongs to the stereo DAC hierarchy within signal-conversion ICs and broader data-conversion semiconductors. Its 24-bit resolution supports high-fidelity playback, while its 192 kHz sampling capability accommodates high-resolution digital audio streams. The WM8524's principal output feature is a 2 V RMS ground-referenced line-level signal for each stereo channel. Unlike a conventional line-output stage that requires large coupling capacitors, its DC servo removes the output DC offset and allows ground-referenced operation. This architecture also effectively reduces power-on pops and clicks and allows the device to drive line outputs without output coupling capacitors. An integral charge pump generates the internal voltage required by the output stage, allowing the converter to operate from a single 3.3 V power rail.

Within the broader hierarchy of ADC/DAC converters, data converters, and integrated circuits, a stereo DAC supports two independent analog output channels. The WM8533ECSN/R operates at up to 192kHz and accepts 24-bit audio data, making its digital audio interface suitable for high-resolution consumer and embedded audio systems. Key verified features include 24-bit resolution, a maximum sample rate of 192kHz, stereo operation, 2Vrms ground-referenced line outputs, and configurable I2C or SPI control. The compact 20-WCSP package is intended for space-constrained designs where a conventional leaded package or larger multi-pin surface-mount package would be inconvenient. Exact device dimensions, pin assignments, clock requirements, supply voltages, and output topology details require confirmation from the manufacturer datasheet. The converter can sit at the output of a digital audio pipeline, receiving serial audio data from a USB interface, audio processor, Bluetooth receiver, or digital transport. I2C is useful for compact control buses, while SPI provides an alternative digital control path. The verified 2Vrms ground-referenced output description indicates that the analog stage is intended for line-level audio rather than direct headphone drive. Typical uses include premium portable audio products, digital media equipment, active speakers, audio docking systems, and embedded playback platforms. In each case, the 24-bit and 192kHz capabilities allow high-resolution source material to be represented, although actual signal fidelity also depends on clocking, analog layout, power quality, output filtering, and the surrounding signal chain. Designers should verify the complete pinout and reference circuit directly against the manufacturer datasheet before PCB layout. The 1.84 mm by 1.77 mm WCSP requires fine-pitch assembly, and the I2C and SPI interface pins, analog outputs, supplies, and ground connections must be routed according to the documented reference layout. This page consolidates verified distributor descriptions, package information, interface details, and selection guidance while clearly identifying parameters that still require datasheet verification. It also records that no verified pin-to-pin replacement candidates were found, avoiding unsupported substitution claims.
