WM8213SCDS/V - 16-Bit 3-Channel 24MSPS AFE | Cirrus Logic
部品番号: WM8213SCDS/V ✓ 生産中WM8213SCDS/V 概要
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.

Contact Image Sensor Document Scanning
The WM8213SCDS/V fits contact image sensor systems that require multiple conditioned sensor outputs and high-resolution digitization. Its three channels provide reset-level clamping, correlated double sampling, programmable gain, and programmable offset before the signals are time-multiplexed into a single 16-bit ADC. At up to 24 MSPS, the device supports fast pixel-rate acquisition, while the 2.97 V to 3.63 V supply range simplifies integration into a 3.3 V scanner design. The 350 mW power rating and shared ADC architecture reduce the conversion channel count compared with three separate high-speed converters.
おすすめ
CCD Line-Scan Imaging
The WM8213SCDS/V is suited to CCD line-scan systems requiring sensor-compatible sampling and a compact three-channel analog front end. Correlated double sampling extracts charge-related information while reset-level clamping establishes a defined signal baseline before conversion. Programmable gain and offset allow each analog channel to be matched to its sensor output, and the three multiplexers support flexible channel selection. The shared 16-bit ADC operates at up to 24 MSPS, making the device appropriate for fast line acquisition where multiple CCD outputs must be converted through a compact package.
おすすめ
Industrial Optical Inspection
The WM8213SCDS/V supports industrial inspection equipment that acquires images from CCD or contact image sensors at high pixel rates. Its three independently adjustable analog paths allow sensor-level gain and offset calibration before the selected channel is digitized. Correlated double sampling reduces signal-source effects that are inherent to charge-transfer imaging sensors, while reset-level clamping provides repeatable baseline control. A maximum rate of 24 MSPS accommodates fast-moving production lines, and the 28-pin SSOP package keeps the analog front end compact enough for camera electronics assembled close to the sensor.
おすすめ
Barcode and Surface Profile Scanning
The WM8213SCDS/V can digitize multiple optical sensor outputs in barcode readers, label readers, and surface-profile scanners. Its 16-bit resolution retains fine variations in reflected-light measurements, while programmable gain and offset simplify adaptation to different sensor sensitivities and illumination levels. The correlated-double-sampling and clamping functions are particularly relevant when the source is a CCD-based line sensor. With three multiplexed input channels, the device supports combined acquisition paths without requiring a separate ADC for each signal, and its 24 MSPS capability covers high-speed line data capture.
おすすめ
Multi-Channel Scientific Imaging
The WM8213SCDS/V is appropriate for compact scientific imaging instruments that need three conditioned sensor channels and precise digital output. All three analog paths share a common 16-bit conversion architecture, reducing component count and simplifying synchronization relative to three independent converters. Adjustable gain and offset permit calibration of the three sensor outputs, while correlated double sampling and reset-level clamping prepare CCD-derived signals for conversion. The device's 2.97 V to 3.63 V analog and digital supply range supports 3.3 V laboratory electronics, while the 28-pin SSOP footprint assists compact instrument construction.
おすすめ
Compact Camera Electronics
The WM8213SCDS/V helps reduce analog-front-end complexity in compact camera electronics built around CCD sensors. Three conditioned inputs feed one time-multiplexed 16-bit ADC, allowing sensor signals to reach the digital processor through a controlled channel count. Its 350 mW power rating is appropriate for space- and power-conscious imaging modules, and the 24 MSPS maximum rate supports rapid pixel transfer. Because the device is supplied in a 28-pin SSOP package, board layout should allow sufficient lead spacing while keeping analog sensor traces short and separate from high-speed digital outputs.

設計ノート
Route each sensor output to its intended analog input through a short, continuous path, and keep the serial clock and data traces away from the high-impedance sensor nodes. The WM8213SCDS/V multiplexes three analog channels into one converter, so unequal trace lengths and crosstalk can appear as channel-dependent errors. Follow the ground and decoupling arrangement in the manufacturer datasheet, place local supply capacitors at the relevant pins, and provide a quiet return path beneath the analog section where the layout rules permit.
Treat the analog sensor connections, reference network, clock distribution, and serial output as separate signal domains. Correlated double sampling and programmable gain depend on clean, repeatable timing, while the 24 MSPS conversion rate increases the importance of controlled clock routing. Use short clock branches, avoid stubs, and keep switching-node or digital-return currents out of the sensor reference area. Validate eye margin, output timing, and channel-to-channel offset using the actual sensor cable, connector, and board stack-up.
Use separate local decoupling paths for the 2.97 V to 3.63 V analog and digital supplies, following the manufacturer datasheet's capacitor values and placement. The device is rated at 350 mW, but total board dissipation depends on conversion activity, clocking, supply voltage, and adjacent circuitry. Estimated calculation: a 3.3 V operating point at the stated 350 mW device rating corresponds to approximately 106 mA of device current; confirm actual operating current under the intended sampling workload before sizing upstream regulators.
