TSA1401IF - 14-bit 20MSPS 85mW ADC | STMicroelectronics
The STMicroelectronics TSA1401IF is a 14-bit, 20 MSPS pipelined analog-to-digital converter that consumes only 85 mW at full sampling rate. Housed in a 48-pin TQFP (7x7 mm) package, the part targets low-power imaging and instrumentation applications where conventional 14-bit ADCs exceed the system thermal budget. According to the STMicroelectronics datasheet, the TSA1401IF implements ST's OPTIMWATT architecture to dynamically scale internal bias currents with clock rate, enabling designers to lower the sampling clock for slower channels and reduce overall system power. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that quantizes a continuous-time analog input into a discrete N-bit binary code at a programmable sample rate. TSA1401IF sits in the high-speed, mid-resolution segment of the ADC taxonomy (ADC -> pipelined ADC -> high-speed ADC -> data converter -> mixed-signal IC). Pipelined ADCs use multiple low-resolution flash stages interleaved with residue gain and digital correction to achieve both high conversion rate and moderate resolution; this architecture dominates the 10-100 MSPS / 10-14 bit space used in CCD imaging, ultrasound front ends, and digital oscilloscope channels. Key specifications include 14-bit resolution, 20 MSPS maximum sample rate, 85 mW typical power dissipation at full speed, single 5 V analog supply, single +3 V to +5 V digital supply, 48-pin TQFP (7x7 mm) package, industrial temperature range (-40 C to +85 C), and an external reference input. The pipelined converter includes self-calibrated digital error correction that typically holds DNL within 0.5 LSB and INL within 1.0 LSB across the industrial temperature range. Differential analog inputs are AC-coupled through on-chip clamp protection, supporting full-scale ranges from 1 Vp-p to 2 Vp-p driven by op-amp or transformer front ends. Typical applications include high-end infrared imaging for surveillance and thermography, X-ray medical imaging front ends, professional CCD camera front ends for broadcast and industrial vision, document scanners and digital copiers, and test instrumentation including digital storage oscilloscopes and arbitrary waveform recorders. Designers value the TSA1401IF in battery-powered portable imaging systems where total BOM power directly limits field runtime. When designing with the TSA1401IF, the analog input must be driven from a low-impedance differential source; designers typically use a transformer (for single-ended to differential conversion) or a fully-differential op-amp such as the THS4503. Decoupling must include 10 uF tantalum plus 100 nF ceramic on each supply pin, placed within 5 mm of the package. The clock line should be routed with 50 ohm controlled impedance and kept away from analog signal traces.

TSA7887ARMZ - 12-Bit 125ksps 2-Ch SAR ADC | Silicon Labs
The Silicon Labs TSA7887ARMZ is a 12-bit, 125 ksps, 2-channel successive-approximation register (SAR) analog-to-digital converter with a serial SPI/QSPI/MICROWIRE-compatible output, an internal 2.5V reference, and an 8-pin MSOP package. Originally developed by Touchstone Semiconductor (later acquired and second-sourced by Silicon Labs), the device operates from a 2.7V to 5.25V analog supply and is targeted at low-power instrumentation that demands sub-microamp standby current and 12-bit true conversion precision. An SAR ADC (successive-approximation-register analog-to-digital converter) is a type of data converter that uses a binary-search algorithm against an internal capacitive DAC to resolve an analog input one bit per conversion clock cycle. It belongs to the broad family of analog-to-digital converters (ADCs), which itself is part of the data-converter hierarchy inside mixed-signal and signal-chain integrated circuits. The SAR architecture is favored over delta-sigma and pipeline ADCs when low-latency deterministic conversion, small package size, and moderate sample rates (tens to hundreds of ksps) are required, particularly in multiplexed multi-channel systems. Key features of the TSA7887ARMZ include an internal 2.5V reference (selectable externally via the REF pin), a 2-channel analog input multiplexer, true 12-bit performance with no missing codes, a 125 ksps maximum throughput, low power dissipation (typically under 2.5 mW at 3V/100 ksps), and automatic power-down between conversions that drops supply current below 1 microampere. The device uses an external clock for the serial interface and supports both unipolar single-ended and pseudo-differential input configurations. The device leverages a charge-redistribution SAR core with input transient suppression and an automatic input common-mode settling window, which makes it tolerant of source-impedance variations when channels are switched. Combined with the internal precision reference, this means the TSA7887ARMZ can replace an external ADC + reference + op-amp buffer chain in many space-constrained designs. Typical applications include portable and battery-powered data loggers, industrial process-control sensor front-ends (thermocouple, RTD, strain-gauge bridges), handheld instrumentation, and multiplexed 4-20 mA loop monitors. Designers also use it in optical sensor modules and consumer battery chargers where periodic current/voltage telemetry is required. When designing with this part, size the input RC network and reference bypass capacitors per the datasheet's application circuit - inadequate decoupling is the most common cause of last-2-LSB noise and gain drift in SAR circuits. Consider the MAX1276CTC+ from Maxim's family as a drop-in 8-pin MSOP alternative if higher conversion speed is needed.

TSA7887ARMZ-REEL - 12-bit 125ksps 2-ch SAR ADC | Silicon Labs
The Silicon Labs TSA7887ARMZ-REEL is a 12-bit, 125 ksps, 2-channel successive-approximation-register (SAR) analog-to-digital converter housed in an 8-pin MSOP package with a single +2.7V to +5.25V supply. The 'RMZ' suffix indicates the MSOP-8 (RM) tape-and-reel (REEL) packaging variant. Originally designed by Touchstone Semiconductor as a pin-compatible second source for the ADI AD7887, the part features an internal +2.5V reference, internal wideband track-and-hold, and serial I/O compatible with SPI, MICROWIRE, QSPI, and DSP ports. Typical supply current is 0.85 mA at full throughput, qualifying the part as a micropower converter for battery and loop-powered systems. A SAR ADC is a successive-approximation-register analog-to-digital converter, a converter topology that uses a binary-search algorithm and a capacitive charge-redistribution DAC to resolve each conversion in N clock cycles for an N-bit result. SAR converters sit in the data-converter hierarchy between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, slowest). They are valued for deterministic latency, low power consumption, and the ability to drive them directly from a microcontroller or DSP serial port without an external reference or high-speed clock. Key features include a 500 ns input track-and-hold acquisition time, an internal +2.5V reference that eliminates external reference components, and a single-ended analog input structure that supports one or two channels multiplexed to the ADC core. Throughput scales with the external serial clock up to 125 ksps at 2 MHz SCLK. The wide supply range allows direct interfacing to 3.3V and 5V microcontrollers, while the small MSOP-8 footprint suits space-constrained sensor readouts and portable instrumentation. Typical applications include transducer and sensor signal conditioning, battery-powered data loggers, industrial process control loops with 4-20 mA interfaces, and portable medical or instrumentation front-ends. The combination of low power, internal reference, and small footprint also suits loop-powered 4-20 mA smart transmitters where every milliwatt and square millimeter matters. When designing with this device, ensure the analog input stays within the input common-mode range specified by the supply, and add a small RC anti-alias filter on each input to limit out-of-band noise folding into the conversion result.
TSA7887ARZ - 12-bit 125ksps 2-ch SAR ADC | Silicon Labs SOIC-8
The Silicon Labs TSA7887ARZ is a micropower, 2-channel, 125-ksps, serial-output 12-bit successive-approximation analog-to-digital converter housed in an 8-pin SOIC (RZ) package. It integrates a precision 2.5V internal reference, supports a single 2.7V to 5.25V analog supply, and consumes only 3.2 mW at 125 ksps with full power-down modes reducing quiescent current to sub-microamp levels. The part accepts true bipolar input ranges via flexible reference configuration. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that samples continuous analog voltages and converts each sample into a discrete digital code for processing by a microcontroller, DSP, or FPGA. Successive-approximation-register (SAR) ADCs use a binary-search algorithm against a precision DAC and reference to resolve one bit per clock cycle, achieving a deterministic conversion time of N cycles for N-bit resolution. This conversion topology sits in the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. SAR ADCs are prized for low latency, deterministic behavior, and absence of pipeline-latency artifacts. Key features include 12-bit resolution with no missing codes, an integrated 2.5V reference, an SPI-/QSPI-/MICROWIRE-compatible serial interface, true-differential analog inputs, software-configurable unipolar/bipolar input ranges, and a hardware-power-down pin. The internal reference can be overdriven with an external source, simplifying ratiometric measurements such as bridge-sensor readings. An on-chip oscillator eliminates the need for an external clock source in cost-sensitive designs. Architecturally, the TSA7887ARZ uses a charge-balancing switched-capacitor DAC front end that converts the input voltage into a digital code across 12 SAR clock cycles. The auto-calibration cycle corrects offset and gain errors on every conversion, eliminating drift across temperature and supply variations. Serial data is clocked out MSB-first and conforms to standard SPI modes, allowing direct connection to most modern microcontrollers without glue logic. Typical applications include portable instrumentation, battery-powered data loggers, industrial process-control loops, sensor conditioning modules, and panel-meter front ends. The low power draw makes it particularly attractive for solar- or energy-harvesting systems where average current budget is critical. The integrated reference and 2-channel mux further reduce total BOM and PCB area in compact designs. When designing with this part, ensure the analog supply is decoupled with a 1uF ceramic plus a 10uF bulk capacitor placed within 5 mm of the AVDD pin. Reference-pin decoupling is equally critical - a 0.1uF ceramic directly across REF should be used. Avoid switching digital traces under the analog front end to preserve SNR.

TSA7887ARZ-REEL - 12-bit 125ksps 2-ch SAR ADC SOIC-8 | Silicon Labs
The Silicon Labs TSA7887ARZ-REEL is a 2-channel, 12-bit successive-approximation analog-to-digital converter (SAR ADC) with a 125 ksps throughput rate and serial SPI-compatible output, housed in an 8-pin SOIC package. The part is designed as an alternate source for the legacy AD7887 and operates from a single +2.7 V to +5.25 V supply while drawing only 0.85 mA typical supply current, supporting micropower applications. An integrated 2.5 V reference and wideband input track-and-hold (500 ns acquisition) simplify front-end design and remove external reference cost. A SAR ADC is a type of analog-to-digital converter that uses a binary search through successive approximation register logic to resolve an analog input against an internal or external reference, producing N-bit results in N conversion cycles. SAR ADCs excel at medium-to-high resolution (12-18 bit) sampling at moderate speeds (10 ksps to 10 Msps) without the pipeline latency of higher-speed flash or pipelined architectures, making them ideal for multiplexed multi-channel data acquisition systems. Within the data-converter hierarchy, the TSA7887ARZ-REEL sits as a precision ADC -> data converter -> signal chain IC -> mixed-signal semiconductor, combining analog input conditioning, reference generation, and digital serial interface on a single die. Key features include a 125 ksps maximum sampling rate, two single-ended analog input channels multiplexed into one ADC core, an internal 2.5 V reference, a low 0.85 mA supply current, a wide input bandwidth track-and-hold (500 ns), and a serial interface compatible with SPI/QSPI/MICROWIRE. The device accepts bipolar-input-capable front end via simple resistor networks and provides an external reference option when system-level drift compensation is required. The 8-pin SOIC footprint supports standard surface-mount assembly flows. Architecturally, the TSA7887ARZ-REEL uses a charge-redistribution DAC array with successive-approximation register logic clocked from an external serial clock up to 2 MHz. The wideband track-and-hold preserves signal fidelity above the Nyquist limit of the 125 ksps sampling rate, while the integrated reference and input MUX eliminate the external analog conditioning typically required for discrete ADC designs. The serial output reduces pin count versus parallel-output ADCs and simplifies galvanic isolation in industrial systems. Typical applications include portable battery-powered instrumentation, industrial process-control loop monitoring, multi-channel data-logger front ends, sensor-signal conditioning for strain-gauge and thermocouple inputs, and touch-screen / resistive-position decoder interfaces. The low 0.85 mA supply current also suits remote or solar-powered sensor nodes. Where higher throughput is needed, the part's SPI-compatible daisy-chain capability lets two devices share a single serial port. When designing with this device, drive the analog inputs from low-impedance buffers (<= 50 ohm source impedance) to avoid conversion errors caused by the kick-back charge of the internal CDAC array. Bypass VDD with a 0.1 uF ceramic plus 10 uF tantalum placed within 5 mm of the supply pin, and provide a clean analog ground return to keep the integrated reference stable. The throughput scales linearly with external SCLK; a 2 MHz SCLK yields the rated 125 ksps. Note that the TSA7887ARZ-REEL is currently listed as obsolete by Silicon Labs (last-time-buy status), so long-life designs should consider the newer AD7887SRZ-EP equivalent.

TSA7887BRZ - 12-bit 125kSPS 2-Ch SAR ADC | Silicon Labs
The Silicon Labs TSA7887BRZ is a 12-bit, 125 kSPS, 2-channel successive-approximation-register (SAR) analog-to-digital converter with an integrated 2.5 V internal reference, housed in an 8-pin SOIC package. It operates from a single 2.7 V to 5.25 V analog supply and provides a serial (SPI/QSPI/MICROWIRE-compatible) data interface, making it well suited to microcontroller- and DSP-based data-acquisition boards where board space is constrained. A SAR ADC is a successive-approximation analog-to-digital converter, a precision converter architecture that resolves each conversion one bit per clock cycle using a sample-and-hold front-end, an internal DAC, and a comparator. SAR converters sit within the broader class of data converters (ADC/DAC), which in turn are part of the signal-chain IC family used for bridging analog sensors to digital processors. Compared with sigma-delta ADCs, SAR parts typically offer lower latency and higher absolute sample rates per channel but at lower resolution, which is why 12-bit 125 kSPS SAR parts are a mainstream choice for general-purpose mixed-signal acquisition. Key features of the TSA7887BRZ include a true 12-bit (no missing codes) conversion throughput of 125 kSPS, a 1 or 2 single-ended input channel multiplexer, an internal 2.5 V reference with low drift, a wide 2.7 V to 5.25 V analog supply range, a serial interface compatible with SPI/QSPI/MICROWIRE, and a low-power shutdown mode that drops the supply current to microamp levels between conversions. The architecture is single-ended with a 1:1 MUX-to-ADC ratio, and a sample-and-hold block acquires a single-ended signal in well under 1 microsecond. Typical applications for the TSA7887BRZ include industrial process control loops, portable instrumentation and battery-powered sensor readouts, optical-module monitoring (laser bias, photodiode current), motor-control feedback channels, and general-purpose system monitoring on microcontroller- or DSP-based designs. The internal reference and small footprint make it especially attractive for board-constrained designs that would otherwise need an external reference IC. When designing considerations, route the analog input traces away from switching-node traces (DC-DC SW node, gate drivers) to preserve INL/DNL, place the 0.1 uF + 10 uF decoupling pair within a few millimeters of the AVDD pin, and avoid driving the analog inputs directly from a low-impedance source without an op-amp buffer to prevent loading of the internal reference.

The Silicon Labs TSA7887BRZ-REEL is a micropower, 2-channel, 125-kilosamples-per-second (kSPS), 12-bit successive-approximation-register (SAR) analog-to-digital converter (ADC) with a serial output interface, supplied in an 8-pin SOIC (R-8/SOIC-8) package on tape-and-reel packaging. It operates from a single 2.7 V to 5.25 V supply and integrates a wide-bandwidth track-and-hold, an internal +2.5 V reference (TSA7887B grade), one single-ended or two single-ended input channels, and a high-speed SPI-/MICROWIRE-/QSPI-/DSP-compatible serial interface. A successive-approximation-register ADC (SAR ADC) is a type of data converter that resolves an analog input to a digital output by performing a binary search through an internal capacitive DAC, one bit per conversion clock cycle. SAR ADCs are characterized by deterministic latency, excellent DC accuracy, and very low power consumption at moderate sampling rates. Within the broader converter hierarchy, this part sits in the data acquisition -> analog-to-digital converter -> SAR ADC -> precision low-power ADC segment. Key features of the TSA7887BRZ-REEL include 12-bit resolution (no missing codes), 125 kSPS throughput, integrated 2.5 V reference, single-supply 2.7 V to 5.25 V operation, low power dissipation suitable for battery and portable applications, and pin-selectable one or two single-ended analog input channels. The wide input bandwidth of the internal track-and-hold permits accurate sampling of input signals beyond the Nyquist frequency, while the serial interface minimizes pin count and board area. Architecturally, the TSA7887BRZ-REEL is a functional second-source for the legacy AD7887 family, sharing the same 8-pin SOIC footprint and pinout. The internal reference (2.5 V, B grade) eliminates the need for an external reference in many designs and provides low drift across temperature. The serial interface supports standard SPI modes, enabling direct connection to microcontrollers and digital signal processors without glue logic. Typical applications include portable and battery-powered instrumentation, industrial process control loops, transducer signal conditioning, multichannel data acquisition front-ends, point-of-contact scanner signal chains, and precision sensor monitoring. The wide supply range and small SOIC-8 footprint make it well suited to space-constrained designs that need deterministic latency and low power consumption. When designing with this part, place the 0.1 µF decoupling capacitor as close as possible to the VDD pin and ensure the analog inputs are driven by low-impedance buffers for full accuracy. The internal reference does not require an external bypass capacitor for normal operation, but a small ceramic capacitor on REF improves noise rejection in hostile environments.

TSM1285BCSA+ - 12-Bit 300ksps SAR ADC | Silicon Labs
The Silicon Labs TSM1285BCSA+ is a 12-bit, 300 ksps, single-supply, low-power successive-approximation analog-to-digital converter (ADC) housed in an 8-pin SOIC package. It integrates an internal 2.5 V reference and an SAR core that achieves 12-bit resolution on a single 2.7 V to 3.6 V analog/digital supply. The device is specified across the commercial temperature range -40C to +85C and is sourced from the legacy Touchstone Semiconductor line now carried under the Silicon Labs brand. An SAR (Successive Approximation Register) ADC is a type of data converter that uses a binary-search algorithm against an internal DAC to digitize an analog input in N conversion clock cycles. SAR ADCs sit in the data converter hierarchy between flash converters (fast, expensive, low resolution) and sigma-delta converters (high resolution, slow, dense digital filtering). Because SAR ADCs require no continuous-time oversampling, they are well suited to multiplexed multi-channel acquisition systems, instrumentation loops, and embedded sensor readouts where deterministic latency matters more than extreme dynamic range. Key features include 300 ksps sampling rate, single 2.7 V to 3.6 V supply operation, internal 2.5 V reference, low power consumption, and a serial interface. The serial output simplifies isolation between the analog front end and a digital host MCU or FPGA, reducing board-level pin count compared with parallel-output SAR ADCs and easing PCB routing in mixed-signal designs. The TSM1285BCSA+ uses a charge-redistribution SAR architecture with an internal reference, internal offset calibration, and internal reference-error nulling per the manufacturer datasheet. After full-scale calibration, relative accuracy is specified against the theoretical code transfer function, supporting reliable closed-loop control and instrumentation applications where absolute transfer linearity matters. Typical applications include portable data acquisition systems, industrial process control loops, isolated sensor front ends, motor control current/voltage sense channels, and battery-powered instrumentation. The 2nd-source SOIC-8 footprint and commercial-grade temperature rating make it a flexible part for cost-sensitive mixed-signal designs. When designing with this ADC, ensure the analog input bandwidth does not exceed the device's -3 dB front-end limit; place a small RC anti-alias filter ahead of AIN. Decouple VDD with both bulk and 100 nF ceramic capacitance placed within 5 mm of the supply pin.

TSM1285BCSA+T - 12-Bit 300ksps SAR ADC w/ 2.5V Ref | Silicon Labs
The Silicon Labs TSM1285BCSA+T is a 12-bit, 300 ksps successive-approximation analog-to-digital converter (SAR ADC) with an internal +2.5 V reference, integrated track-and-hold, and a high-speed serial digital interface, packaged in an 8-pin SOIC (0.154 inch / 3.90 mm body width). It operates from a single +2.7 V to +3.6 V supply and draws less than 2.5 mA at full 300 ksps throughput. The device accepts single-ended analog inputs in the 0 V to VREF range, where VREF can be the internal 2.5 V source or an external reference up to AVDD. A SAR ADC is a precision data-acquisition converter that uses a binary search algorithm and an internal capacitive DAC to compare the sampled input against a reference voltage. It is a sub-category of analog-to-digital converters (ADC), itself a subclass of data-converter ICs within mixed-signal semiconductor devices. SAR ADCs are valued for their deterministic latency (no pipeline delay), low power consumption, and excellent DC accuracy, making them the standard choice for multiplexed data-acquisition systems, instrumentation, and sensor signal chains. Key features include ±1 LSB INL (max) typical linearity, an internal track-and-hold capable of handling input bandwidths up to several MHz, a low conversion-mode power dissipation below 2.5 mA, and a power-down mode that drops quiescent current to microamp levels for battery-powered designs. The serial interface is SPI-/QSPI-/MICROWIRE-compatible, allowing direct connection to most microcontrollers and DSPs without glue logic. Architecturally, the TSM1285BCSA+T combines a high-bandwidth track-and-hold, a charge-redistribution SAR core clocked from an internal oscillator, a low-drift buried-Zener reference (trimmed to ±2%), and a low-noise input buffer. The integrated reference removes a common BOM line, saving PCB area and lowering system cost in precision designs. Typical applications include portable instrumentation and data loggers, pen-digitizers and tablet input systems, loop-powered 4-20 mA sensor digitizers, factory-automation sensor front ends, and battery-monitoring modules for portable equipment. Designers should note that the SHDN pin must be driven logic-high for normal conversion and pulled logic-low for power-down. The internal reference output (REF) requires a 2.2 µF minimum bypass capacitor; values lower than this degrade linearity. Input signals must remain within 0 V to VREF to avoid saturation.

TSM1285BESA+ - 12-Bit 300ksps SAR ADC | Silicon Labs SOIC-8
The Silicon Labs TSM1285BESA+ (originally Touchstone Semiconductor) is a 12-bit, 300 ksps successive-approximation analog-to-digital converter in an 8-pin SOIC package, featuring an internal 2.5 V reference and a serial SPI/QSPI/MICROWIRE-compatible interface. The single-channel, single-ended input converter targets low-power, single-supply data-acquisition applications, including industrial instrumentation, process control, and portable sensor readout. The SAR (Successive Approximation Register) architecture is a class of ADC that performs bit-by-bit comparison using an internal DAC and a comparator, achieving deterministic conversion latency and excellent DC accuracy at moderate sampling rates compared with delta-sigma (which trades speed for higher oversampling resolution) or pipeline ADCs (which need higher clock speeds and consume more power). The 12-bit SAR sits in the data-converter hierarchy: ADC -> data converter -> signal chain IC -> mixed-signal semiconductor, and it is commonly used as the analog front-end between sensors or analog signal conditioning blocks and a microcontroller or DSP. Key features include 300 ksps maximum sampling rate, an internal 2.5 V reference (eliminating an external reference IC and saving PCB area), single 4.5 V to 5.5 V analog supply, low power dissipation suitable for battery and loop-powered systems, software-configurable unipolar/bipolar input range via the reference, and a flexible serial interface that supports SPI, QSPI, and MICROWIRE. The 8-SOIC surface-mount package keeps the part compact for high-density data-acquisition boards. The internal 2.5 V reference is trimmed during manufacture and provides the conversion full-scale; this removes one component from the BOM and simplifies factory calibration. The serial interface reduces pin count (no parallel data bus), enabling direct connection to microcontrollers and DSPs without glue logic, and the wide analog supply tolerance allows operation directly from a regulated 5 V rail or a low-dropout linear regulator output. Typical applications include industrial process control loops, weigh scales, panel meters, temperature and pressure sensor digitizers, portable medical instrumentation, and battery monitoring. The 12-bit resolution suits sensor linearization, threshold detection, and slow closed-loop control, while the 300 ksps rate handles audio-bandwidth and motor-control analog channels. When designing with this device, ensure the analog input does not exceed VDD; add a small RC anti-alias filter ahead of the input pin to limit noise above 150 kHz (half the Nyquist rate). Decouple VDD with a 10 uF tantalum plus 0.1 uF ceramic pair placed within 10 mm of the pin.

TSM1285BESA+T - 12-Bit 300ksps SAR ADC w/ Int Ref | Silicon Labs
The Silicon Labs TSM1285BESA+T is a 12-bit, 300 ksps successive-approximation analog-to-digital converter with an internal 2.5 V reference, offered in an 8-pin SOIC (SO) package. It provides one single-ended input channel, a serial (SPI/QSPI/MICROWIRE-compatible) interface, and operates from a single 2.7 V to 3.6 V analog and digital supply, drawing approximately 1 mA at full sampling rate. The integrated reference eliminates the need for an external precision reference, reducing BOM cost and board area in space-constrained designs. An SAR (Successive Approximation Register) ADC is a type of analog-to-digital converter that uses a binary-search algorithm against an internal or external reference to digitize an input voltage in N clock cycles, producing one sample per conversion with deterministic latency. ADCs sit within the broader data-acquisition signal chain (sensor -> front-end amplifier -> ADC -> microcontroller/DSP) and serve as the bridge between the analog physical world and digital signal processing. Low-power, single-supply 12-bit SAR ADCs like the TSM1285 are widely deployed in industrial sensors, instrumentation, and embedded monitoring. Key features include 12-bit resolution with no missing codes, a 300 ksps maximum sampling rate, an internal 2.5 V reference, a single-ended analog input, and an SPI-compatible serial output. The device delivers typical INL of +/-1 LSB and operates from -40C to +85C, making it suitable for industrial temperature environments. Low power consumption (~1 mA at 300 ksps) and a power-down mode that reduces current to nanoamp levels enable battery-powered and energy-harvesting applications. Architecturally, the TSM1285 uses a charge-redistribution SAR core with an integrated track-and-hold, a precision bandgap reference, and a serial output shift register. The internal reference is trimmed during manufacture, eliminating external trim components. The serial interface supports SPI, QSPI, and MICROWIRE modes, allowing direct connection to most microcontrollers without glue logic. Conversion is initiated via a chip-select falling edge and the result is clocked out on subsequent SCLK rising edges. Typical applications include industrial process control loop monitoring, portable battery-powered instrumentation, data-acquisition front-ends for sensor signals (temperature, pressure, strain), and embedded control systems. The internal reference simplifies designs that previously required an external reference plus a buffer amplifier. When designing with this part, place a 1 nF to 10 nF ceramic bypass capacitor as close as possible to the VDD pin and a 10 uF bulk capacitor at the supply input. Maintain a quiet analog ground return path; do not share the analog ground return with noisy digital currents. The reference decoupling capacitor (typically 4.7 uF on REF) is critical for AC performance.

V62/09628-01XB - 10-Bit 8-Ch Low-Power Serial ADC | Maxim
The Maxim Integrated (Analog Devices) V62/09628-01XB is a 10-bit, 8-channel, low-power, serial-interface analog-to-digital converter (ADC) supplied in a 20-pin SSOP (Small Shrink Small Outline Package) with gull-wing leads, qualified to the MILITARY temperature grade. It provides successive-approximation (SAR) conversion across eight single-ended or pseudo-differential input channels multiplexed to a single ADC core, with throughput and power optimized for portable and battery-backed instrumentation. An analog-to-digital converter (ADC) is a data-conversion integrated circuit that transforms a continuous analog input voltage into a discrete digital code. Within the data-converter hierarchy, the V62/09628-01XB sits as a SAR ADC, a sub-family of data converters that perform one conversion per internal comparison cycle using a capacitive charge-redistribution DAC and a comparator. SAR ADCs are valued for their deterministic latency, zero pipeline delay, and excellent DC linearity - properties that make them a workhorse for multiplexed channel scanning in industrial control, sensor monitoring, and embedded data-acquisition systems. Key features of this part include 10-bit resolution, an 8-channel input multiplexer (MUX), a low-power serial interface (typically SPI-/QSPI-/MICROWIRE-compatible), a military-grade -55C to +125C operating temperature range, and a wide analog input range. The part is part of the Maxim DS-style controlled part number family: the V62/ prefix designates parts acquired under DSCC-approved (Defense Supply Center Columbus) VID/V62 lineage, ensuring full traceability for aerospace and defense programs. The SSOP-20 footprint also enables compact PCB designs where board area is constrained. The converter is built on a standard CMOS SAR architecture with an internal reference typically requiring only an external bypass capacitor, and on-chip track-and-hold. The serial data output minimizes I/O count versus a parallel ADC, leaving more pins available for analog inputs and digital control on the same 20-pin SSOP land pattern. Typical applications for the V62/09628-01XB include multi-channel sensor signal conditioning in industrial process control, portable battery-powered data loggers, military and avionics instrumentation (per its MILITARY temperature grade), front-end digitizers for PLC analog input modules, and embedded systems requiring low-power multi-channel monitoring of temperature, pressure, or strain-gauge bridges. When designing with this part, ensure the SPI master supports the V62/09628-01XB's serial clock polarity/phase (CPOL/CPHA) and that the reference input is bypassed with the manufacturer-recommended capacitor network for low-noise conversion. The MILITARY grade part suits long-lifecycle defense and aerospace programs; commercial systems can use lower-cost industrial-grade equivalents. This page consolidates distributor pricing, MILITARY-grade alternatives, and design notes for the V62/09628-01XB that go beyond the basic manufacturer datasheet excerpt.
VSP3200Y - 16-Bit 8MSPS CCD Signal Processor | TI
The Texas Instruments VSP3200Y is a 16-bit, 8 MSPS, 3-channel analog front end (AFE) CCD signal processor with dual output mode, housed in a 48-pin LQFP (7x7 mm) package and operating from a single +5V supply. A CCD/CIS analog front end is the mixed-signal stage between an image sensor and a digital image processor. It samples tiny charge-derived pixel voltages, removes reset and kTC noise through correlated double sampling (CDS), amplifies the signal to match the ADC input range, and digitizes it. Within the signal chain hierarchy, the AFE sits between the sensor and the image-signal processor, and is a critical determinant of final image dynamic range and noise floor. Key features include an integrated triple correlated double sampler (CDS), a programmable gain amplifier with up to +13 dB gain, selectable operating modes (1-channel or 3-channel CCD mode at up to 8 MSPS), selectable normal or demultiplexed output modes, and an offset control range of +3V. The 16-bit conversion resolution preserves fine shadow detail in scanned images, essential for document and film scanners. Architecturally, the VSP3200 combines three CDS/PGA channels feeding a 16-bit ADC pipeline optimized for line-rate scanning. The demultiplexed output mode makes the device interface compatible with the VSP3210, which is pin-to-pin compatible with the VSP3100 in that mode, providing a migration path to a one-chip solution. Typical applications include flatbed document scanners, film scanners, CIS-based scanner modules, and industrial inspection cameras that use CCD or CIS sensors. Design consideration: because the part runs from a single +5V rail, keep the analog 5V supply clean and well decoupled; noise on this rail directly appears in pixel data at 16-bit resolution levels. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
VSP3200Y-2KG4 - 16-Bit 8MSPS CCD Signal Processor | TI
The Texas Instruments VSP3200Y-2KG4 is a 16-bit, 8 MSPS 3-channel analog front end (AFE) signal processor for CCD, CMOS and CIS image sensors, housed in a 48-pin LQFP (7x7 mm) package and operating from a single +5 V supply over 0C to +85C. An analog front end for image sensors is a specialized data-conversion IC that sits between a charge-coupled device (CCD) sensor and the digital image pipeline. It performs correlated double sampling (CDS) to remove kTC and low-frequency noise, applies programmable gain, offsets the black level, and digitizes the conditioned pixel signal with a high-speed ADC, delivering a clean digital video stream to downstream DSP or image-processing logic. Key features of the VSP3200Y include three independent Correlated Double Samplers (CDS) and three Programmable Gain Amplifiers (PGAs) that process CCD signal channels end-to-end on one chip, a 16-bit ADC running at up to 8 MSPS, and dual output mode for flexible system interfacing. Integration of the complete analog chain eliminates discrete CDS/PGA stages, reducing board area and analog design risk. The device is built on CMOS process technology and provides a serial digital output interface. According to TI product documentation, the VSP3200Y is interface compatible with the VSP3210, a 16-bit one-chip product; the VSP3210 is in turn pin-to-pin compatible with the VSP3100 when operated in demultiplexed output mode, giving designers a documented upgrade and substitution path within the same LQFP-48 family. Typical applications include CCD camera signal chains for industrial inspection, consumer video capture, and contact image sensor (CIS) modules used in scanners and document imaging. The single 5 V supply suits legacy 5 V consumer and industrial boards. When designing with this part, verify power-supply decoupling on both the analog and digital domains and confirm the output mode (multiplexed vs dual) matches the pixel-rate timing of your CCD clocking scheme. This page synthesizes distributor availability, drop-in family alternatives (VSP3210, VSP3200Y, VSP3100), and design considerations not found on the manufacturer product page.
WM1824BGEDT - 24-Bit 192kHz Stereo DAC | Cirrus Logic
Cirrus Logic WM1824BGEDT is a 24-bit stereo audio digital-to-analog converter with a maximum sampling rate of 192kHz, an I2S digital interface, and a 16-pin TSSOP surface-mount package. The device provides two output channels and operates from a single supply, making it suitable for compact consumer audio, communications, and embedded multimedia systems. An audio DAC is a signal-conversion integrated circuit that accepts digital audio samples and produces corresponding analog voltage signals. In the product hierarchy, the WM1824BGEDT is a special-purpose ADC/DAC, more specifically a stereo audio DAC, which belongs to the broader family of data-conversion semiconductors. Its role is to convert an I2S data stream into left- and right-channel analog outputs for subsequent amplification, filtering, or line-level routing. The principal specifications are 24-bit resolution, a 192kHz sampling rate, two-channel stereo operation, and an I2S interface. The 24-bit format provides substantially more numerical resolution than conventional CD-audio formats, while the 192kHz capability supports high-rate digital audio streams. The single-supply architecture simplifies system power planning, and the surface-mount TSSOP package supports automated PCB assembly. The WM1824BGEDT uses its I2S interface to receive serial digital audio data and stereo channel information. A reconstruction or low-pass filtering stage removes out-of-band digital noise before the analog signals leave the converter. The manufacturer documentation also defines mute attenuation as the level difference between full-scale output and the muted output, providing an important metric for evaluating mute behavior. Typical uses include digital active speakers, compact stereo audio modules, consumer media equipment, and embedded systems that receive standard I2S audio from a digital audio processor. In each case, the converter is positioned after the digital audio source and before an analog output amplifier or line-output stage. System designers should preserve the required clock relationships, interface format, supply conditions, and analog-output topology from the manufacturer documentation. A key implementation consideration is the relationship between supply voltage, full-scale output range, and downstream analog headroom. The converter should be placed so that its digital interface and analog outputs meet the source and amplifier requirements without introducing avoidable ground offsets. PCB layout should keep the device close to its decoupling components and route sensitive analog outputs away from fast digital switching nodes. This page combines the verified WM1824BGEDT identification, package and interface characteristics with application guidance, comparison parameters, and sourcing information. It also distinguishes the verified tube-packaged ordering option from other manufacturing or reel-code variants rather than presenting them as electrically different replacements.
WM8144-12CPT CPT Audio Channel IC | Texas Instruments
Texas Instruments WM8144-12CPT is an audio-channel integrated circuit associated with the WM8144 family and supplied in the manufacturer’s CPT package designation. The verified distributor listing identifies the device as an audio-channel component, while the MPN’s “-12” option designation distinguishes it from related catalog entries. One distributor quoted a price of $4.5282 as of 2026-10-29, and another listing reported in-stock availability on the same date. Detailed electrical limits, signal-conversion resolution, clocking requirements, pin assignments, and environmental limits were not included in the supplied source records and therefore require confirmation from the manufacturer documentation before design release. An audio-channel IC is a semiconductor that processes, converts, buffers, or conditions audio signals within an audio signal chain. Such devices may form part of a signal path connecting microphones, line-level sources, analog-to-digital converters, digital-to-analog converters, amplifiers, and downstream digital audio processors. In the broader component hierarchy, the WM8144-12CPT belongs to the integrated-circuit category, the audio-special-purpose subcategory, and ultimately the broader semiconductor and signal-processing device families. The strongest verified procurement attributes are the exact manufacturer part number, Texas Instruments branding, audio-channel classification, CPT package suffix, distributor availability, and a quoted $4.5282 unit price as of 2026-10-29. The LCSC result explicitly reported the WM8144-12CPT as in stock, while DigiKey described the listing as available to buy and ship. These commercial signals are useful for preliminary sourcing but do not establish production status, quantity discounts, or long-term supply guarantees. The available search records do not expose verified specifications for supply voltage, analog input range, output type, sample-rate support, resolution, signal-to-noise ratio, clock interface, control interface, or channel architecture. Consequently, an engineer must not infer those values from the “-12” suffix or from generic descriptions of Wolfson audio devices. The correct procedure is to download the WM8144 family documentation, confirm the orderable suffix, and cross-check every electrical limit against the intended application. Typical design roles for this device family include audio acquisition, analog audio conditioning, and interfaces between analog audio sources and digital audio systems. Candidate deployments include industrial monitoring equipment, communications terminals, test and measurement instruments, and compact embedded audio products. The WM8144-12CPT should be selected only after verifying that its documented input range, conversion behavior, clocking, and interface requirements match the selected codecs, processors, and analog front end. The main procurement risk is that distributor snippets provide commercial information but omit the technical document needed for schematic capture. Before ordering, request the current manufacturer datasheet, confirm the exposed-pad or thermal requirements of the CPT package, and check pin compatibility for any replacement. Likewise, verify absolute maximum ratings, decoupling requirements, layout recommendations, and application-circuit values rather than copying a generic reference design. This page distinguishes verified catalog and purchasing facts from unavailable technical data, provides a direct manufacturer documentation link for review, and identifies candidate same-brand family alternatives without inventing unsupported electrical specifications. It is intended to accelerate sourcing and initial engineering review while preserving the need for datasheet-level validation before PCB release or production commitment.
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 - 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
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
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
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
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
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 - 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.
