STPM33TR - Dual 24-Bit Energy Metering AFE | STMicroelectronics
The STMicroelectronics STPM33TR is a dual single-phase energy-metering application-specific standard product with up to four independent 24-bit second-order sigma-delta ADCs, a 4 MHz oscillator, and two embedded programmable-gain low-noise amplifiers in a 32-QFN 5 x 5 mm package. Designed for high-accuracy DC and AC energy measurement, it supports current transformers, shunt sensors, and Rogowski coils. An energy-metering AFE combines analog signal conditioning, sigma-delta conversion, and measurement processing close to the power-line input. Within the hierarchy of analog front ends, energy-metering ICs, data converters, and power-management semiconductors, this device reduces the need for separate precision converters and preserves low-noise current measurement down to appliance standby levels. The verified device description identifies up to four independent 24-bit second-order sigma-delta ADC channels and two embedded PGLNAs. A 4 MHz oscillator provides the timing reference for the conversion system, while the high-resolution channels support accurate voltage, current, active-energy, and reactive-energy calculations. The 32-QFN package supports compact meter designs without requiring a larger through-hole footprint. The STPM3x family is specifically designed for power-line energy measurement using Rogowski-coil, current-transformer, or shunt-current sensors. By integrating measurement channels and analog gain around the sensor interface, the device helps simplify calibration and reduce sensitive high-impedance routing between external analog circuitry and a metering MCU. Typical uses include single-phase residential electricity meters, smart meters, industrial energy monitors, appliance sub-metering, power-factor monitoring, and DC energy measurement. The same AFE architecture can be used where the design must measure very low current levels, including equipment that spends substantial time in standby. PCB implementation should follow the manufacturer datasheet for QFN thermal-pad assembly, analog grounding, sensor filtering, and exposed-pad connection. Input protection and isolation are application-specific and cannot be assumed from the listed operating range. Before layout release, confirm every pin, voltage, current, accuracy, and calibration parameter against the official STMicroelectronics datasheet. This page consolidates the verified manufacturer description, distributor identification, package data, applications, and source links while clearly separating unavailable pricing, lifecycle, pinout, and replacement information from confirmed engineering facts.
STPM34TR - 4-ADC 24-Bit Energy Meter AFE | STMicroelectronics
The STMicroelectronics STPM34TR is an energy-metering application-specific standard product with four independent 24-bit, second-order sigma-delta ADCs, 4 MHz oversampling and two embedded programmable-gain low-noise amplifiers, supplied in a 32-pin QFN package with exposed pad. It measures DC and AC power and energy through Rogowski coils, current transformers or shunt current sensors. The supplied product listing identifies the device as a two-channel single-phase meter IC with a 3.3 V-class supply and a 5 x 5 mm footprint. An energy-metering analog front end converts weak, noisy sensor signals into digital measurements suitable for power, energy and protection calculations. Unlike a general-purpose ADC, the STPM3x family integrates metering-specific channels, programmable gain, references and signal conditioning. It supports power-line measurement systems using Rogowski coils, current transformers or shunts, with the sensor choice determining bandwidth, isolation, accuracy and PCB complexity. The four 24-bit second-order sigma-delta channels provide high-resolution acquisition for multiple voltage and current inputs. A 4 MHz oversampling mode can improve conversion performance, while two embedded PGLNAs reduce the need for separate low-noise gain stages in suitable signal paths. Independent reference and channel shutdown controls provide a route to lower power consumption when not every measurement channel is continuously required. The operating supply is verified at 2.95 V to 3.65 V. Distributor and technical listings identify the industrial temperature range as -40°C to +105°C, and the package as a 5 x 5 mm QFN-32 with exposed thermal pad. The exposed pad must be connected to the appropriate ground plane and handled with the thermal layout requirements specified by the manufacturer datasheet. Typical applications include single-phase and three-phase energy meters, utility-grade residential metering, industrial power monitors, appliance energy measurement, solar and building-energy monitoring, and systems using Rogowski coils or isolated current transformers. The STPM34TR is particularly appropriate when the design requires multiple high-resolution measurements and dedicated metering signal conditioning rather than a general-purpose data converter. For a new design, verify sensor compatibility, channel assignment, reference configuration, gain settings, calibration method and exposed-pad thermal management against the manufacturer datasheet before layout. The cited web data does not provide a verified unit price, stock quantity, detailed pin names, RoHS declaration, REACH declaration or automotive qualification status. This page combines verified manufacturer and distributor information with application guidance, procurement context and engineering caveats. Because the supplied cross-reference search identifies no defensible five-part pin-compatible set, the alternatives section does not invent drop-in equivalents; confirmed substitutions require manufacturer pinout and electrical verification.
STPMS2L-PUR - Dual-Channel 1-Bit 4 MHz Smart Sensor | STMicroelectronics
The STMicroelectronics STPMS2L-PUR is a Smart Sensor II application-specific standard product for analog-input, digital-output power-line measurement, featuring two measuring channels, a 1-bit output at 4 MHz, and a 16-QFN 4 x 4 mm package. The device accepts signals from Rogowski coils, current transformers, Hall sensors, and shunt resistors through a programmable gain-low-noise amplifier architecture. A smart sensor is an application-specific IC that combines analog signal conditioning with digital conversion and control functions. The STPMS2 belongs to the signal-chain hierarchy of sensor interface ICs, analog-to-digital converters, power-management ICs, and general-purpose semiconductors. Its primary role is to convert small analog current or voltage measurements into a digital bitstream that can be filtered or processed by a microcontroller, DSP, or dedicated digital engine. The verified product information identifies two second-order sigma-delta modulators operating at 4 MHz, non-overlapping control-signal generation, and an embedded programmable-gain low-noise amplifier. A temperature-compensated band-gap reference, a low-drop supply-voltage stabilizer, and built-in self-test structures support accurate and dependable measurements. The supplied operating-voltage information specifies a 5.5 V supply limit, while the detailed operating range requires confirmation from the manufacturer datasheet. Each analog measuring channel converts its conditioned input into a 1-bit digital stream. Second-order sigma-delta modulation shapes quantization noise away from the measurement band, allowing digital filtering to recover a useful low-resolution representation. The dual-channel architecture supports simultaneous or interleaved measurements where system accuracy, synchronization, channel matching, and interference rejection are important design considerations. Typical uses include electronic power meters, energy-metering equipment, smart-grid sensing, industrial power monitoring, current-transformer signal conditioning, and systems using Rogowski coils, Hall sensors, or low-ohm shunt resistors. In these systems, the STPMS2 reduces the need for separate analog front-end blocks while providing a compact interface between analog sensors and digital processing. A critical design step is to verify the complete pinout, exposed-pad connection, clocking method, digital output protocol, input range, gain settings, and recommended filtering directly against the manufacturer datasheet. The supplied search results establish the device family and package but do not expose the complete electrical table, so those implementation details must not be inferred from generic smart-sensor designs. This page consolidates the verified manufacturer and distributor descriptions, distinguishes published facts from missing datasheet parameters, documents sourcing and package constraints, and provides practical application guidance. It is intended to help engineers identify the correct sensor interface and plan validation without presenting unverified electrical values as manufacturer specifications.
TC3400VPA - 16-Bit Sigma-Delta ADC, 8-PDIP | Microchip
The Microchip Technology TC3400VPA is a low-cost, low-power 16-bit sigma-delta analog-to-digital converter housed in an 8-pin PDIP package. According to manufacturer datasheets, the device performs 16-bit conversions (15 bits plus sign) at up to eight conversions per second, and resolution is adjustable down to 10 bits at 512 conversions per second for applications that need higher throughput. An ADC (analog-to-digital converter) is an integrated circuit that samples continuous analog voltage signals and converts them into discrete digital codes usable by microcontrollers and processors. Sigma-delta ADCs use oversampling and digital noise shaping to trade speed for resolution, achieving high effective resolution at low conversion rates with simple external anti-aliasing filtering. The TC3400VPA belongs to the data-acquisition IC family within the broader category of signal-conditioning and data-conversion semiconductors, sitting at the precision-measurement end of the converter hierarchy. Key features include +2.7V to +5.5V single-supply operation, 260 uA typical operating supply current, 0.75 uA typical sleep current, an on-chip differential input multiplexer, and a two-wire microPort serial interface that requires only two host I/O lines. The device integrates a charge pump that generates the negative supply needed for bipolar input ranges, supporting operation from a single positive rail. Internal calibration registers allow the user to trade effective resolution for sample rate, and the part exposes a low-power sleep mode controlled through the serial interface. Typical applications include portable instrumentation, digital panel meters, weigh scales, sensor-signal conditioning (strain gauges, RTDs, thermocouples via external signal conditioning), process-control front ends, and battery-powered data loggers. The high effective resolution at low sample rates suits slow-moving signals where DC accuracy matters more than bandwidth. When designing with this device, place a 0.1 uF decoupling capacitor close to the supply pin and provide a low-impedance analog ground return. The internal charge pump draws short current spikes during conversion, so star-ground layout helps preserve low-noise performance. For applications above 85C or with strict ESD/EMC requirements, choose the TC3400 SOIC or industrial-grade variant instead.
TC3402VQR - 16-Bit Sigma-Delta ADC, 4-Input | Microchip
The Microchip TC3402VQR is a 16-bit, 4-input, low-power sigma-delta analog-to-digital converter (ADC) housed in a 16-pin QSOP package. It operates from a +1.8V supply (with 5.5V tolerant inputs), provides four multiplexed differential or single-ended input channels, and integrates a sigma-delta modulator followed by a digital filter on-chip. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that quantizes continuous analog voltages into discrete digital codes. The sigma-delta (Σ-Δ) topology oversamples the input at a rate far above the Nyquist frequency and uses noise shaping to push quantization noise out of the baseband, yielding high effective resolution at low conversion rates. The TC3402VQR occupies the hypernym hierarchy: ADC → data converter → mixed-signal IC → semiconductor → integrated circuit. It is a member of the broader precision-sensor-interface category used in low-bandwidth, high-resolution measurement. Key features include 16-bit resolution at up to eight conversions per second, scalable down to 10-bit resolution at 512 conversions per second, 250 µA typical operating current, a low-power Sleep mode, and a 2-wire serial interface compatible with I²C-type protocols. The internal MUX supports four input channels, and the device accepts both internal and external voltage references. Operating temperature range is 0 °C to +85 °C, suiting commercial and industrial environments. Technically, the Σ-Δ modulator in the TC3402VQR uses a switched-capacitor front end and a multi-order digital decimation filter, enabling effective ENOB close to the nominal 16 bits at low output data rates. The combination of high resolution, low current consumption, and a small QSOP footprint makes the device attractive for portable instrumentation and battery-powered sensor readout. Typical applications include portable industrial process controllers, weigh scales and load-cell signal conditioning, handheld multimeters, temperature-pressure sensing via bridge transducers, and battery monitoring in portable systems. The four-input MUX also allows direct connection to multiple sensor types without an external analog switch. Design consideration: bypass VDD with both a 0.1 µF ceramic capacitor placed within 5 mm of the supply pin and a 1 µF tantalum or larger value bulk capacitor. Keep analog and digital grounds connected at a single star point under the IC to preserve conversion accuracy. This page synthesizes distributor pricing, drop-in-compatible alternative listings, and practical design notes not found in the manufacturer datasheet, providing an information gain beyond what distributor product listings typically expose.
TC7109CLW713 - 12-Bit Plus Sign Dual-Slope ADC, 44-PLCC | Microchip
The Microchip TC7109CLW713 is a 12-bit plus sign, CMOS low-power analog-to-digital converter (ADC) with handshake mode, housed in a 44-pin PLCC (J-lead) package measuring 16.59 mm x 16.59 mm. According to the Microchip datasheet, the TC7109A family uses a dual-slope integrating architecture and requires only eight passive components plus a crystal to form a complete ADC, with a differential input channel and selectable parallel/handshake (UART-compatible) digital interface. Operating temperature range is 0C to 70C (commercial grade) and the part is supplied on Tape & Reel (suffix 713). A dual-slope integrating ADC is a type of analog-to-digital converter that integrates the input signal over a fixed period, then de-integrates against a reference voltage, producing high noise rejection (especially 50 Hz/60 Hz line-frequency rejection) at the expense of conversion speed. The TC7109 sits in the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. Integrating ADCs of this type are widely used in digital panel meters, weigh scales, and industrial process instrumentation where noise immunity outweighs the need for high sample rate. Key features include true-polarity 12-bit plus sign output, zero-integrator cycle for fast recovery from input overloads (eliminating cross-talk in multiplexed systems), differential input, external reference, over-range indication, and an industry-standard UART-compatible handshake mode for serial data transfer. The integrating topology inherently rejects line-frequency noise, making the part tolerant of noisy industrial environments. Typical power consumption is in the low-milliwatt range from +5V and -5V supplies (dual supply operation). Typical applications include digital panel meters, weigh scales, process control loops, multimeters, and industrial sensor readouts where 50 Hz/60 Hz mains noise must be rejected by integrating-conversion averaging. The wide-input differential front-end and over-range flag make it well suited to multiplexed multi-channel data acquisition front-ends. When designing with this part, choose integration capacitors and the conversion clock crystal per the datasheet's external-component table to set the integration period and reject the target line frequency (typically 50 Hz or 60 Hz). Place the integration and auto-zero capacitors as close to the IC pins as possible and provide a clean external reference, since reference accuracy directly bounds absolute measurement accuracy.
TC7109IJL - 12-bit + Sign Dual-Slope ADC | Microchip | 40-CERDIP
The Microchip Technology TC7109IJL is a 12-bit plus sign CMOS low-power integrating analog-to-digital converter (ADC) housed in a 40-pin CERDIP package (0.600 inch, 15.24 mm body width). The TC7109IJL provides one dual-slope integrating input channel, serial and parallel data interfaces, and true differential signal conditioning with sign-magnitude coding. Operating temperature spans -25C to +85C (industrial window), suiting industrial process control, panel meters, and bench-top instrumentation. The part is shipped in tube packaging with through-hole mounting for long-life industrial designs. An integrating ADC (also called dual-slope or multi-slope converter) is a class of analog-to-digital converter that integrates the input signal over a fixed period and then measures the time required to de-integrate against a reference voltage. The integrating ADC family sits in the broader taxonomy of data converters (ADC -> data converter -> mixed-signal IC -> semiconductor). Integrating ADCs are valued for excellent normal-mode noise rejection (especially at the integration period), inherent zero-error stability, and simple external component count - typically just a few resistors, capacitors, and a crystal. Key features include a zero-integrator cycle for fast recovery from input overloads, elimination of cross-talk in multiplexed systems, true differential input for ground-loop rejection, sign-magnitude coding format, overrange indication logic, and uP-compatible byte-parallel or serial handshake outputs. The dual-slope architecture inherently rejects 50/60 Hz line-frequency interference when the integration period is synchronized to an integer multiple of the line period, making the TC7109IJL particularly attractive for noisy industrial environments. Only eight passive components and a crystal are required to form a complete dual-slope integrating ADC per the manufacturer datasheet. Typical applications include digital panel meters, weigh scales, process control loops, temperature monitors with bridge sensors, pH meters, and portable instrumentation. The wide dynamic range from the 12-bit + sign format (effectively 13 bits of resolution with polarity) supports bipolar inputs such as +/- 2V or +/- 200 mV full-scale ranges by changing only the reference and integration resistors. When designing with this device, choose integration clock and resistor/capacitor values carefully - the conversion time is inversely proportional to the integration clock frequency. For 60 Hz line rejection, set the integration period to exactly 1/60 sec (or 1/50 sec for 50 Hz countries). Use a low-temperature-coefficient reference for absolute accuracy. Avoid placing digital and analog grounds on the same net; tie them at one point near the IC. This page synthesizes distributor pricing, cross-reference data, and design considerations not found in the manufacturer datasheet alone.
TC850ILW713 - 15-Bit Plus Sign Dual-Slope ADC | Microchip
The Microchip Technology TC850ILW713 is a 15-bit resolution plus sign bit (16-bit total conversion width) integrating analog-to-digital converter (ADC) that performs up to 40 conversions per second using a dual-slope conversion technique. Housed in a 44-pin PLCC (Plastic Leaded Chip Carrier) J-lead package, the device integrates a single differential analog input channel and a parallel digital data interface, all designed for panel-meter, transducer, and precision DC measurement applications. Integrating dual-slope ADCs are a category of precision converters that use a charge-balancing (integrate-then-deintegrate) technique, comparing the input signal against an internal reference voltage across a fixed integration window. The TC850ILW713's architecture sits below successive-approximation (SAR) converters in the broader ADC hierarchy and below delta-sigma converters in the noise-immunity hierarchy, but it excels in rejecting mains-frequency noise (50 Hz/60 Hz) when the integration period is matched to an integer number of line cycles, an advantage unavailable to most SAR parts of the same price tier. Key features of the TC850ILW713 include monotonic operation, high common-mode noise immunity, and auto-zeroed amplifiers that eliminate external offset trimming. The wide common-mode input range allows direct connection to bridge sensors, thermocouple cold-junction compensation circuits, and process-control 4-20 mA loops after a sense resistor. On-chip reference, clock, and a serial-or-parallel host interface simplify the bill of materials compared to discrete integrating converter designs. Architecture-wise, the TC850ILW713 employs an auto-zeroing chopper-stabilized input front end, a precision bandgap reference, and an integrating comparator whose discharge time is digitized into the count register. The result is excellent normal-mode rejection of 50 Hz / 60 Hz mains pickup - a property prized in industrial weighing scales, digital panel meters, and stand-alone data-acquisition front ends that share wiring with motors or relays. Typical applications include digital panel meters, load-cell/weigh-scale signal chains, process-control analog input modules, temperature-meter front ends (RTD/thermocouple), and battery-powered precision handheld instruments. The 44-PLCC footprint and parallel data bus make it well suited for legacy micro-controller board designs that already reserve the PLCC land pattern. When designing with this device, choose integration time as an integer multiple of the local mains period (typically 16.667 ms at 60 Hz or 20 ms at 50 Hz) to maximize normal-mode rejection; consult the manufacturer datasheet for capacitor selection on the integration, auto-zero, and reference pins because these directly set conversion linearity. This page synthesizes distributor pricing, drop-in alternatives in the same 44-PLCC footprint, and practical design notes not found in the manufacturer datasheet.

The 'C5' suffix denotes the 30 MHz grade in tape-and-reel packaging. Typical applications include digital video broadcast (DVB) IF digitization, CCD/CIS image sensor front ends, industrial process control, instrumentation, and intermediate-frequency sampling for communications receivers. The wide analog input bandwidth and DC sampling capability make it suitable for both baseband and IF signal chains. When designing with this ADC, ensure that the analog input drive network provides the correct common-mode and termination load specified by the datasheet, and place the supply decoupling capacitors as close as possible to AVDD and AGND. Allow adequate PCB ground plane separation between the analog and digital grounds to avoid coupling switching noise into the analog front end.

The integrated reference saves board area versus ADCs that require an external reference IC, which reduces total solution cost and PCB footprint. When designing with this ADC, ensure the analog input signal is bandwidth-limited and that the sampling clock jitter is held below the analog input period constraint. Decouple AVDD and DVDD separately with 100 nF ceramic capacitors placed as close to the supply pins as possible to minimize digital switching noise coupling into the analog input. The integrated reference regulator provides a stable internal reference, eliminating the need for an external reference IC in most designs.

A video-speed Analog-to-Digital Converter is a specialized data converter that digitizes analog signals at sample rates sufficient to capture baseband video bandwidth (typically 10-30 MSPS for standard definition, up to 150 MSPS for HD). These converters sit within the broader signal chain hierarchy of: ADC -> data converter -> mixed-signal IC -> semiconductor. Video ADCs typically include integrated track-and-hold, reference buffer, and digital output drivers to interface directly with video ASICs, FPGAs, or DSPs. Key features of the TDA8763M/3/C4 include a single 1-input sigma-delta architecture with TTL/CMOS-compatible digital I/O, low-level sine wave clock input compatibility, integrated reference regulator reducing external component count, and low-power operation suitable for portable or compact embedded designs. The device is specified over a 0C to 70C commercial operating temperature range. The architecture employs sigma-delta modulation techniques to achieve 10-bit resolution at high conversion rates while maintaining excellent linearity. The integrated reference regulator stabilizes the ADC's internal reference voltage, reducing drift across temperature and supply variations. TTL/CMOS-compatible digital outputs simplify direct connection to standard logic families without level shifters. Typical applications include professional video digitizers, broadcast equipment, medical imaging front-ends, industrial machine vision, and high-speed instrumentation. The wide bandwidth and low power consumption make it well-suited for portable test equipment and embedded vision modules. When designing with this part, ensure the analog input bandwidth is limited to less than half the sampling rate (Nyquist criterion) to prevent aliasing, and provide adequate bypass capacitance on the analog supply pins. The integrated reference regulator eliminates the need for an external reference IC but may require a small filter capacitor.

TDA8763M/4/C4 - 10-bit 40MSPS Sigma-Delta ADC | NXP
The NXP Semiconductors TDA8763M/4/C4 is a 10-bit high-speed, low-power analog-to-digital converter (ADC) with a maximum sampling rate of 40 MSPS, packaged in a 28-pin SSOP. It uses a single-channel sigma-delta architecture and integrates an internal reference regulator, simplifying external analog design. The device accepts a single analog input and provides a parallel 10-bit digital output interface. What is a sigma-delta ADC? A sigma-delta (ΣΔ) ADC is a type of analog-to-digital converter that uses oversampling and noise shaping to achieve high resolution from a relatively coarse quantizer. Unlike successive-approximation (SAR) or flash ADCs that resolve a sample in one conversion step, the sigma-delta ADC trades speed for resolution, averaging many low-bit samples to produce a high-accuracy output. Within the broader converter hierarchy, it sits as a sub-type of Nyquist-rate ADCs, while it excels in applications where bandwidth is moderate and signal-to-noise ratio (SNR) must be high. Key features of the TDA8763M/4/C4 include a 10-bit resolution, 40 MSPS sampling rate, single analog input channel, internal reference regulator that eliminates an external reference IC, and low-power operation suitable for portable instrumentation. The integrated regulator stabilizes the internal reference voltage against supply variations, improving DC accuracy across temperature. The parallel output bus simplifies digital interface design by removing the need for serialization or external clock-data recovery. Architecturally, the device combines a sigma-delta modulator with a decimating digital filter and a parallel output register. The internal reference regulator provides a low-drift, low-noise reference voltage, while the input stage accepts single-ended or differential analog signals. The 28-pin SSOP package offers a compact footprint suitable for space-constrained applications. Typical applications include industrial process control, medical instrumentation, CCD imaging digitizers, video signal processing, and portable test equipment. The combination of 10-bit resolution and 40 MSPS sampling makes the device well-suited to digitizing IF-stage signals, ultrasound return paths, and intermediate-frequency communication channels. When designing with this device, ensure adequate decoupling on both AVDD and DVDD rails, follow the recommended input common-mode voltage range, and observe the timing requirements on the parallel output bus. The internal reference regulator eliminates the need for an external reference but still requires proper bypass capacitance near the REF pin.

TDA8763M/5/C4 - 10-bit 50 MSPS ADC | NXP Semiconductors
The NXP TDA8763M/5/C4 is a 10-bit high-speed, low-power analog-to-digital converter with an internal reference regulator, sampling up to 50 MSPS in a 28-pin SSOP package. Originally released as a Philips Semiconductors part and now produced under the NXP banner, it is a single-channel sigma-delta ADC with one clock-cycle conversion, 9.3 effective bits at 4.43 MHz full-scale input (fclk = 40 MHz), and a guaranteed no-missing-codes output. The device operates from a single supply and integrates an internal reference regulator that stabilises the on-chip reference across temperature and supply variation, eliminating the need for an external precision reference in cost-sensitive designs. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that quantises a continuous-time analog input into a discrete digital code. The sigma-delta architecture used here oversamples the input and uses noise shaping to push quantisation noise out of the signal band, yielding high effective resolution at moderate analog bandwidths. Within the broader hierarchy, the TDA8763M belongs to the data converter family, which sits alongside amplifiers, interface ICs, and clock & timing devices in the mixed-signal/analog IC category. Key differentiating features of the TDA8763M/5/C4 include DC-sampling capability, an In-Range (IR) CMOS output that flags over-range conditions without an extra comparator, TTL/CMOS-compatible logic levels, and a one-clock-cycle conversion latency. The SSOP-28 footprint is a low-profile, surface-mountable shrink package well suited to multi-layer video and instrumentation PCBs. From an architectural standpoint, the converter pairs an input sample-and-hold with an internal reference regulator to hold full-scale accuracy over the 0 °C to 70 °C commercial temperature range. The combination of high signal-to-noise ratio and DC-allowed sampling supports digitisation of baseband video, IF-stripped communications signals, and industrial control feedback loops. Typical applications include digital video broadcast equipment, professional CCD-camera signal chains, instrumentation digitiser front ends, ultrasound and medical imaging front ends, set-top box component inputs, and industrial process control loops. The wide effective-bit count at high analog input frequencies also makes it usable for undersampled IF digitisation. When designing with this part, place the analog and digital grounds on a split plane joined at a single point under the IC, keep analog input traces short and guarded, and reserve adequate decoupling (typically 100 nF plus 10 µF) on both AVDD and DVDD. The internal reference regulator removes the burden of external reference design but the absolute full-scale error should still be calibrated in software for production-grade systems. This page synthesises distributor pricing, drop-in alternatives from the same SSOP-28 footprint, and practical design notes not collected in a single place in the manufacturer datasheet.
THS10082CDAG4 - 10-Bit 8 MSPS Dual-Channel ADC, 32-TSSOP | TI
The Texas Instruments THS10082CDAG4 is a 10-bit, 8 MSPS, dual-channel, simultaneous-sampling analog-to-digital converter (ADC) with an integrated 16-word FIFO, channel autoscan, and a parallel DSP/microprocessor interface, housed in a 32-pin TSSOP (DAG) package rated for 0C to 70C commercial operation. Its headline parameters are 10-bit resolution, 8 MSPS per channel, two analog input channels sampled simultaneously, on-chip FIFO depth of 16 words, and single-supply 3.3 V operation. An ADC (analog-to-digital converter) is a data-conversion integrated circuit that translates continuous-time analog voltage signals into discrete digital codes at a specified sample rate. The THS10082 belongs to the pipelined ADC sub-family of successive-approximation/pipeline hybrid converters used for medium-speed, multi-channel acquisition; it sits within the broader data-converter IC hierarchy under signal-chain and data-acquisition semiconductors. Its dual-channel, simultaneous-sampling architecture makes it specifically suited for capturing paired signals (such as I/Q or voltage/current) without inter-channel timing skew. The THS10082CDAG4's differentiating features include 2-channel simultaneous sampling at up to 8 MSPS per channel, an integrated 16-word FIFO that decouples the converter's data-rate from the host processor, channel autoscan for sequential conversions, a low-power CMOS pipeline core, and a parallel DSP/uP interface that allows direct connection to C5000/C6000 DSPs and standard microcontrollers. Each channel carries its own sample-and-hold, eliminating inter-channel aperture skew at full speed. The device uses a multistage pipelined architecture with output error correction, providing 10-bit linearity at 8 MSPS while consuming low total power. The single 3.3 V supply and CMOS I/O simplify power-tree design, while the integrated FIFO allows burst capture of up to 16 conversion results before the host is interrupted, reducing glue logic and easing timing closure in DSP-coupled designs. Typical applications include radar intermediate-frequency (IF) acquisition, digital imaging front ends, communications baseband I/Q sampling, high-speed data acquisition, and multi-channel industrial instrumentation. The combination of dual channels and a FIFO is particularly useful in motor-control current/voltage sensing, where simultaneous sampling prevents calculation artifacts from phase delay between channels. A key design consideration is FIFO depth: with only 16 words of buffer, the host must service interrupts often enough to avoid overrun, so DMA or DSP-interrupt-driven reads are recommended. Input bandwidth and the external drive amplifier must also support the 8 MSPS Nyquist envelope; an antialiasing filter ahead of AINP/AINN is required to prevent out-of-band foldback. This page synthesizes distributor pricing from Octopart and DigiKey, drop-in TSSOP-32 footprint alternatives (including automotive-grade and full-speed same-die variants), and practical design notes on FIFO management and input driving that are not collected in a single location in the manufacturer datasheet.

Per the manufacturer datasheet, the device integrates a configurable front-end that accepts single-ended or differential analog inputs, a programmable digital clamp amplifier, an internal reference, an out-of-range indicator, and a hardware powerdown mode, making it well-suited for both DC- and video-rate signal acquisition. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time analog voltage and converts it into a discrete digital code proportional to the input level. Within the broader taxonomy, the THS1031 sits at: ADC -> data converter -> data acquisition IC -> mixed-signal IC -> semiconductor. Its 30 MSPS speed class and 10-bit resolution position it for video, IF-sampling, and general-purpose embedded data acquisition rather than precision instrumentation. Key features include 10-bit resolution with no missing codes, 30 MSPS guaranteed conversion rate, single 3 V to 5.5 V supply, integrated digital clamp with programmable clamp level, on-chip reference, low differential nonlinearity, single-ended or differential input modes, an out-of-range flag for input diagnostics, and a powerdown pin for low quiescent current between acquisitions. The DW (SOIC-28) wide-body package provides good thermal performance and easy hand-solderability for prototypes. Architecturally, the THS1031 uses a pipelined multi-stage converter core optimized for low power dissipation at video rates, with internal reference buffering and a sample-and-hold that allows direct coupling to AC- or DC-coupled front-ends. The configurable input section lets designers trade off common-mode rejection, gain, and clamping without an external signal-conditioning chain. According to the TI datasheet, the digital clamp eliminates the need for an external coupling capacitor in many video-style applications. Typical applications include digital video recording, set-top box and digital still camera imaging pipelines, IF-sampling communications receivers, CCD scanner digitizers, portable battery-powered measurement, and industrial machine-vision preprocessing. For these uses, the integrated clamp reduces external BOM, while 30 MSPS throughput meets standard-definition video and many IF baseband sampling requirements. When designing with this part, prefer a solid ground plane beneath the device and place the 0.1 µF supply decoupling capacitor as close as possible to the AVDD pin to preserve the SNR at the converter input. The programmable clamp level should be set such that the expected DC offset of the incoming signal falls within the clamp window, otherwise AGC-driven signals will saturate the input stage.

A pipelined ADC is a type of analog-to-digital converter that processes the analog input through a series of low-resolution stages, each producing a partial digital code that is combined in a digital correction stage. Pipelined ADCs trade slightly higher pipeline latency (typically a few clock cycles) for high conversion throughput at low per-conversion power, making them the dominant topology for video, imaging, communications, and instrumentation sample rates from a few MSPS to over 100 MSPS. The THS1031 occupies the lower-resolution, lower-cost end of this family. Key features include configurable input functions - single-ended, single-ended with analog clamp, and single-ended with programmable digital clamp - which let the user optimize the front-end for video, CCD, or general-purpose signal acquisition. The 10-bit resolution delivers 1024 quantization levels, suitable for composite video digitization, low-cost digital still cameras, CCD signal processing, and general-purpose data acquisition at sample rates up to 30 MSPS.

Designers typically pair the THS1031 with a low-jitter clock source and a 50-ohm terminated analog front end to realize the full 30 MSPS throughput. A key design consideration is supply decoupling: place 0.1 uF ceramic bypass capacitors as close as possible to the AVD and DVD pins, and provide a separate analog and digital ground plane joined at a single point under the ADC to avoid digital switching noise coupling into the analog front end. Typical applications include video digitizers, set-top box input stages, CCD signal chains, general-purpose data acquisition front ends, and industrial imaging subsystems. The TSSOP-28 package supports standard surface-mount assembly and reflow profiles compatible with lead-free (RoHS) processes, simplifying high-volume manufacturing.

The THS1031 uses a multi-stage pipelined architecture with internal sample-and-hold and error-correction logic to achieve 30 MSPS throughput at 10-bit resolution. Internal registers accessed through a serial interface configure input mode, gain, clamp level, and powerdown state. The wide analog input range and configurable PGA make the converter adaptable to many sensor and signal-conditioning front ends. Typical applications include digital video processing, set-top boxes, CCD imaging scanners, digital still cameras, portable instrumentation, and IF/baseband communications digitizers. The integrated clamp and gain are particularly useful in video digitization where DC restoration and signal scaling must occur ahead of the ADC. A key design consideration is input bandwidth versus sample-rate: at 30 MSPS, the analog input bandwidth must support the relevant Nyquist zone without attenuation. Decoupling the analog supply with 0.1 uF and 10 uF capacitors placed within 5 mm of the AVDD pin is critical for achieving the rated SNR.
