TLV2544QDRG4 - 12-Bit 200kSPS 4-Ch SAR ADC | Texas Instruments
The Texas Instruments TLV2544QDRG4 is a 12-bit, 200-kSPS, 4-channel, low-power, serial-output successive-approximation-register (SAR) analog-to-digital converter with AutoPower-Down, supplied in a 16-pin SOIC (D) package. It operates from a single 3 V to 5.5 V analog supply, integrates a built-in reference, conversion clock, and an 8× FIFO, and targets cost- and power-sensitive multi-channel data-acquisition systems. The Q-suffix designates the automotive temperature grade (-40 °C to +125 °C), and the G4 suffix denotes tape-and-reel packaging with Pb-free finish. A SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm against a precision DAC to resolve each input sample in N clock cycles, where N is the resolution in bits. SAR ADCs offer deterministic latency, no pipeline delay, excellent dynamic performance at moderate sample rates, and very low standby power - features that make them ideal for multiplexed sensor systems, motor-control feedback loops, and instrumentation where every conversion must complete in a known time. The TLV2544QDRG4 inherits all of these SAR traits and adds hardware (CS) and software (S/W) AutoPower-Down control, dropping supply current after each conversion to extend battery life in portable and remote installations. The device digitizes up to four single-ended inputs through an internal analog multiplexer at up to 200 kSPS aggregate throughput, and provides a 4-wire SPI/QSPI/MICROWIRE-compatible serial interface. AutoPower-Down reduces quiescent current to a few microamps between conversions, and differential non-linearity / integral non-linearity errors are specified at ±1.2 LSB maximum up to 125 °C. A signal-to-noise-plus-distortion ratio above the SNR figure cited for the family supports 12-bit effective resolution at the full sampling rate. Architecturally, the TLV2544QDRG4 combines a charge-distribution DAC array, a high-bandwidth input sample-and-hold, an internal 2.5 V reference (or external reference option via REFin), a digital conversion-control state machine, and the AutoPower-Down timing block. The reference and oscillator are fully internal, eliminating external components and shrinking BOM cost in space-constrained systems. Typical applications include automotive sensor interfaces, multi-channel industrial process control, battery-powered portable instrumentation, motor-speed/temperature monitoring, and any multi-channel data logger that needs deterministic low-latency 12-bit conversion. Compared with the TLV2548Q (which is the 8-channel pin-compatible cousin of the same family), the TLV2544QDRG4 trades two analog input channels for a smaller BOM footprint when only four channels are required. During design, keep analog and digital grounds tied to a single star point near the AGND pin, decouple AVDD with a 10 µF tantalum plus 0.1 µF ceramic combination within 5 mm of the pin, and observe the device's 200 kSPS maximum throughput budget when sequencing multi-channel conversions.
TLV2545ID - 12-Bit 200 kSPS Serial ADC | Texas Instruments
Texas Instruments TLV2545ID is a 12-bit, single-channel, pseudo-differential successive-approximation analog-to-digital converter with a maximum conversion throughput of 200 kSPS, an integrated conversion clock, and serial output compatibility up to 10 MHz. The device operates from a single 2.7 V to 5.5 V supply and is packaged in an 8-pin SOIC (D). It is suited to industrial measurement, sensor acquisition, DSP interface, and embedded control systems where a compact, low-power ADC with serial data output is required. An ADC is a data-acquisition semiconductor that converts an analog voltage into a numeric code for processing, storage, or transmission. The TLV2545 belongs to the ADC and DAC category, using the successive-approximation-register architecture to balance conversion speed, energy use, and implementation complexity. Its single pseudo-differential input arrangement supports measurement of one analog channel against a selectable reference-side connection, while the serial interface reduces the number of signals required when connecting the converter to a microcontroller, DSP, or programmable logic device. The TLV2545ID provides 12-bit conversion resolution, 200 kSPS maximum throughput, and operation from 2.7 V to 5.5 V. Its built-in conversion clock eliminates the need for an external timing source during ordinary sampling. Published family specifications also identify a 140 kSPS version within the TLV254x family, plus integrated and differential nonlinearity limits of ±1 LSB maximum, a signal-to-noise-plus-distortion ratio of 72 dB, and a spurious-free dynamic range of 85 dB. The serial output is described as SPI/DSP-compatible and compatible with TMS320 systems operating up to 10 MHz. The TLV2545ID is designed for low-power, mixed-signal systems. Its serial interface allows the analog input, digital interface, and supply references to be placed close to the sensor or signal source, which can reduce board area and simplify routing. The 8-pin SOIC package is also available in a more compact surface-mount footprint than a through-hole package, making the device practical for compact control and measurement equipment. Designers should still observe the datasheet limits for input range, reference voltage, acquisition time, clock timing, and supply sequencing. Typical uses include industrial sensor interfaces, battery-powered portable instruments, audio and control signal monitoring, and data acquisition front ends feeding a TMS320-compatible processor. The 200 kSPS throughput supports substantially faster sampling than many general-purpose low-speed ADCs, while the 12-bit code width provides 4096 quantization levels. In each application, the analog source, reference arrangement, and digital interface must be evaluated together because conversion accuracy depends on the complete signal chain, not only the converter itself. The principal design consideration is preserving the ADC's dynamic performance through careful reference and layout choices. Input and reference paths should be short, quiet, and appropriately decoupled according to the manufacturer datasheet, while the digital clock and serial data lines should be routed to limit coupling into the analog input. This page combines the verified manufacturer and distributor information with practical application guidance, alternative-selection constraints, and design notes that help distinguish the TLV2545ID from broader functional equivalents that are not necessarily pin-compatible.
TLV2545IDGKR - 12-Bit 200 kSPS Serial ADC | Texas Instruments
The Texas Instruments TLV2545IDGKR is a 12-bit, 200 kSPS successive-approximation analog-to-digital converter with a serial output, housed in an 8-pin VSSOP (DGK) package. Operating from a single 2.7 V to 5.5 V supply, the part features a 1-channel single-ended or pseudo-differential input, integrated conversion clock, autopower-down between conversions, and SPI/DSP-compatible serial interface that supports up to 10 MHz clock rates and TMS320 DSP connections. An ADC (analog-to-digital converter) is a data-conversion integrated circuit that samples a continuous analog voltage and produces a discrete digital code, and a successive-approximation-register (SAR) ADC does so by iteratively comparing the input against an internal DAC, achieving an excellent balance of speed, accuracy, and power consumption for precision low-frequency and audio-bandwidth signals. The TLV2545 belongs to the broader hierarchy of data-converter ICs, which sit within signal-chain and power-management semiconductor families. Key features of the TLV2545 include ±1 LSB maximum INL and DNL, 72 dB SINAD, and 85 dB SFDR at a 20 kHz input tone, along with a 3.5 µs typical conversion time and a flexible SCLK/FS-compatible serial interface. The autopower-down feature reduces current draw to a few microamps between conversions, which is critical for battery-powered and energy-harvesting applications where average load matters more than peak throughput. The architecture uses a charge-redistribution SAR core with an internal sample-and-hold and on-chip oscillator, eliminating the need for an external clock. The pseudo-differential input stage simplifies board layout by accepting ground-referenced signals without a negative rail, while the wide supply range permits direct interface to 3.3 V microcontrollers, 5 V DSPs, or low-voltage battery stacks. Typical applications include portable instrumentation, motor-control feedback loops, battery monitoring, sensor signal conditioning, point-of-load monitoring in industrial control, and audio-bandwidth digitization for consumer audio and telecommunications equipment. The 8-pin VSSOP footprint suits space-constrained designs. When designing with the TLV2545, place 100 nF decoupling close to the supply pin and follow layout practices that keep digital return currents away from the analog input. The SCLK clock rate must remain within the 10 MHz SPI specification, and CS falling-edge timing relative to SCLK should be reviewed against the TMS320 interface diagrams in the datasheet. This page synthesizes distributor pricing, drop-in same-package alternatives drawn from the same TI VSSOP-8 ADC family, and practical layout notes that go beyond what the manufacturer datasheet alone provides.
TLV2545IDGKRG4 - 12-Bit 200kSPS Serial ADC, MSOP-8 | Texas Instruments
The Texas Instruments TLV2545IDGKRG4 is a 12-bit, 200 kSPS, low-power, serial-interface analog-to-digital converter (ADC) using successive-approximation architecture in an 8-pin MSOP (DGK) PowerPAD package. It operates from a single 2.7 V to 5.5 V analog supply, supports a single pseudo-differential analog input, and includes a built-in conversion clock, an SPI/DSP-compatible serial interface up to 10 MHz, and an Auto-Power-Down mode that reduces current consumption to under 1 µA between conversions. An ADC (analog-to-digital converter) of this type is a precision data converter that quantifies an analog input voltage into a binary code. The TLV2545 belongs to the successive-approximation register (SAR) ADC family — a sub-class of general-purpose, low-latency converters — within the broader data-converter hierarchy of ADC/DAC ICs. SAR ADCs are favored when deterministic latency, simple serial interfacing, and low power dissipation are required, making them a common choice over delta-sigma ADCs for multiplexed or control-loop applications. Key features include ±1 LSB maximum INL and DNL, 72 dB SINAD, 85 dB SFDR at a 20 kHz input, 3.5 µs conversion time, Auto-Power-Down that activates at end-of-conversion, and TMS320-compatible serial output. The DGK MSOP-8 with PowerPAD provides a low thermal-resistance path, enabling reliable operation across the industrial -40 °C to +85 °C temperature range. The TLV2545 uses charge-redistribution SAR architecture with an internal sample-and-hold and a precision DAC. The integrated Auto-Power-Down dynamically reduces consumption to sub-microamp levels between conversions, allowing the part to serve battery-powered, event-driven, or polled systems without the overhead of an external analog switch. Typical applications include portable instrumentation and battery-powered sensors, industrial process control loops, multi-channel data-acquisition front-ends, digital signal processor (DSP) and microcontroller analog front ends, optical-networking monitoring, and touch-screen or panel-metering subsystems. When designing with this ADC, place the 1.5 nF CS capacitor and 10 µF bypass capacitor close to the supply pins, route the analog and digital grounds in a star or split-plane topology, and ensure the reference decoupling (REF decoupling capacitor) is short and noise-free. The internal oscillator and Auto-Power-Down mean no external clock is required for stand-alone operation. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical PCB-layout design notes that go beyond the manufacturer datasheet.
TLV5580IPWG4 - 8-Bit 80 MSPS Low-Power ADC | Texas Instruments
The Texas Instruments TLV5580IPWG4 is an 8-bit, 80 MSPS low-power analog-to-digital converter (ADC) with a pipelined architecture, housed in a 28-pin TSSOP (PW) package rated for the industrial -40C to +85C temperature range. The part delivers 700 MHz typical analog input bandwidth, internal top/bottom reference voltages, and an adjustable full-scale reference input for flexible system calibration. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples a continuous analog waveform and produces a discrete binary code proportional to the input amplitude. The TLV5580 belongs to the pipelined ADC family, which sits in the hierarchy: ADC -> data converter -> data acquisition IC -> mixed-signal semiconductor. Pipelined ADCs use multiple low-resolution stages to achieve high sample rates at modest power, making them a standard choice for IF-sampling communications, CCD imaging, and digital oscilloscope front ends. Key features of the TLV5580 include 80 MSPS maximum sampling rate, single 3.3 V supply operation, 3.3 V TTL/CMOS-compatible digital I/O that simplifies interface to modern FPGAs and ASICs, an internal bottom-plate reference that reduces external component count, and an adjustable reference input for gain trim. The 700 MHz analog input bandwidth supports undersampling architectures where the ADC digitizes IF frequencies well above Nyquist. The 28-TSSOP (PW) footprint is pin-compatible across the broader TLV/TLC ADC family from Texas Instruments. Architecturally the device uses a multi-stage pipeline with internal sample-and-hold and digital error correction. The combination of 80 MSPS and 8-bit resolution keeps per-conversion power low (single-digit mA from a 3.3 V rail), which is the original design target: applications where the ADC must sit on the same board as noisy digital logic without dominating the power budget. The TLV5580 has been replaced by the ADS831 in TI's portfolio but remains specified and available for legacy designs. Typical applications include CCD imaging digitizers, video capture front ends, IF-sampling communications receivers, portable battery-powered instrumentation, and digital oscilloscope input stages. In each case the part provides a compact, low-power, single-supply path from analog to digital. When designing with the TLV5580, decouple AVDD and DVDD separately close to the package and follow standard pipelined-ADC layout practice: keep analog input traces short, use a ground plane under the analog input, and provide a clean 3.3 V rail. The PW suffix indicates tube packaging; the device is also offered in tape and reel as TLV5580IPWR.
TLV5590ED - 2-Bit FLEX Pager ADC | Texas Instruments
The Texas Instruments TLV5590ED is a 2-bit analog-to-digital converter designed for FLEX pager chipset signal processing, supplied in a 14-pin small-outline package. It operates from a single supply as low as 2.7 V and uses a proprietary conversion method. The device supports peak and valley detection, selectable dual-bandwidth filtering, fast-track and slow-track operating modes, hold, and standby operation. According to the available manufacturer datasheet information, the associated filtering provides a selectable 1 kHz or 2 kHz bandwidth, each specified with ±5% tolerance, and uses a three-pole Butterworth low-pass response. An analog-to-digital converter is an interface IC that converts continuously varying analog signals into digital codes for processing, measurement, or control. A 2-bit ADC can represent four quantization levels, making it appropriate for compact control and detection systems rather than precision instrumentation. In the TLV5590 application, the converter operates inside a FLEX pager chipset alongside a compatible decoder and external peak or valley detection circuitry. Its position in the hierarchy is ADC, data-conversion IC, interface IC, semiconductor. Key features include the 2-bit proprietary-method conversion, support for both peak and valley detectors, selectable dual-bandwidth audio filtering, and a low-power standby mode. Fast-track mode supports rapid acquisition, slow-track mode supports a different measurement update behavior, and hold preserves the converter state when needed. Standby reduces activity when the pager is not receiving or processing useful signal information. The single-supply operation down to 2.7 V also helps the device fit compact, battery-powered pager designs. Technically, the TLV5590ED is part of a mixed analog and digital signal-processing chain. Its analog input is conditioned by filtering and detection circuitry before conversion. The resulting digital representation is intended for comparison and control within the chipset rather than high-resolution signal capture. The manufacturer datasheet describes the operating modes and their functional roles, but the supplied search data does not expose the complete timing table, transfer function, input impedance, or absolute maximum ratings; those details must therefore be confirmed in the original document before design release. Typical applications include FLEX-format pagers, battery-operated two-way messaging terminals, compact receiver modules, and legacy FLEX chipset designs requiring the TLV5591 decoder. In such systems, the converter supports peak and valley level detection while the selectable filter bandwidth can be matched to the modulation and receiver characteristics. Standby operation is particularly useful where average battery consumption matters more than continuous conversion. The primary design consideration is that this is a specialized 2-bit converter rather than a general-purpose high-resolution ADC. PCB implementation should preserve the package pin assignments and supply-decoupling recommendations in the manufacturer datasheet. Before substituting a different converter, engineers must verify package, pinout, input range, output coding, timing, filter response, and chipset protocol compatibility; a generic ADC with similar resolution may not be interchangeable. This page consolidates the verified product identity, distributor availability, datasheet-linked operating features, and substitution constraints for the TLV5590ED. It also distinguishes documented characteristics from parameters that remain unavailable in the retrieved data, reducing the risk of treating a legacy pager ADC as a generic precision converter.
TLV5617A - Dual 10-Bit DAC, 2.7-5.5V | Texas Instruments
The TLV5617A is a dual 10-bit voltage output digital-to-analog converter (DAC) from Texas Instruments, designed for low-power and space-constrained applications. It operates from a single 2.7V to 5.5V supply and features a flexible 3-wire serial interface compatible with TMS320, SPI, QSPI, and Microwire serial ports. The device is available in an 8-pin SOIC package (TLV5617AID) and includes a power-down mode to conserve energy. A digital-to-analog converter (DAC) is an electronic circuit that converts digital binary data into an analog voltage or current. The TLV5617A is a voltage-output DAC, meaning it produces a voltage proportional to the digital input. It is part of the broader family of data converters, which are essential in mixed-signal systems where digital processing must interface with the analog world. DACs are used in applications such as audio playback, motor control, and sensor calibration. Key features of the TLV5617A include dual 10-bit resolution, programmable settling time (fast mode: 3 µs, slow mode: 10 µs), and a rail-to-rail output buffer with Class-AB stage. The device also offers a power-down mode that reduces quiescent current to 1 µA, making it ideal for battery-powered equipment. The serial interface accepts a 16-bit word consisting of 4 control bits and 10 data bits, allowing flexible configuration. The TLV5617A uses a resistor-string architecture with a x2 gain rail-to-rail output buffer, ensuring low glitch energy and monotonic performance. The output buffer can drive capacitive loads up to 100 pF without external compensation. The device is specified over the industrial temperature range of -40°C to +85°C and is RoHS compliant. Typical applications include programmable voltage sources, digital gain and offset adjustment, and industrial process control. The low power consumption and small package make it suitable for portable instrumentation and battery-powered devices. The serial interface simplifies connection to microcontrollers and DSPs, reducing board space and pin count. When designing with the TLV5617A, ensure that the reference voltage is stable and bypassed with a 0.1 µF capacitor. The power supply should be decoupled with a 1 µF capacitor close to the VDD pin. The serial clock frequency should not exceed 20 MHz to maintain reliable communication.
TLV5627IPW - 8-Bit Quad DAC, Serial, TSSOP-16 | Texas Instruments
The Texas Instruments TLV5627IPW is a quad-channel, 8-bit voltage-output digital-to-analog converter (DAC) with a flexible 4-wire serial interface, packaged in a 16-pin TSSOP (PW) and operating from a 2.7V to 5.5V supply. Each of the four DAC channels features programmable settling time of either 2.5 µs (fast mode) or 8.5 µs (slow mode) and supports a 107 kSPS update rate, enabling both precision setpoint generation and waveform synthesis from a single chip. A digital-to-analog converter (DAC) is a mixed-signal integrated circuit that converts a digital codeword into a precision analog voltage or current; an 8-bit quad DAC like the TLV5627 delivers four such converters on one die with a shared digital interface, sitting within the broader hierarchy of converter ICs > data converters > signal chain > mixed-signal semiconductors. Unlike audio DACs that target continuous high-rate streaming, the TLV5627 is an industrial/multi-channel "set DAC" intended for bias voltages, trim references, programmable gain stages, and actuator control loops where four independent low-bandwidth analog outputs are required. Key features include a glueless serial interface compatible with TMS320 DSP, SPI, QSPI, and Microwire ports, an on-chip reference input buffer, hardware and software-controlled power-down modes that cut consumption to a few milliwatts, and guaranteed monotonic output over the full -40C to +85C industrial temperature range. The four outputs share a common DAC reference, but each channel can be powered down independently for further energy savings. Internally, the TLV5627 uses a resistor-string architecture with an output buffer amplifier per channel, providing low output impedance and the ability to drive 2 kohm loads directly. The dual-supply design separates the digital and analog domains (separate AVDD and DVDD pins), which is critical for noise-sensitive applications where digital switching transients must be isolated from the analog outputs. Typical applications include industrial process control (PLC analog outputs), programmable sensor excitation, digital offset and gain trimming, four-channel waveform or bias generation in test & measurement, motor and valve control loops, and audio tone/signal generation where mid-fidelity is acceptable. When designing with this device, ensure the AGND and DGND pins are joined at a single low-impedance point near the IC to prevent digital return currents from corrupting analog output accuracy. The reference input must be driven from a low-noise source, and the unused DAC outputs can be left open or tied to a defined voltage. Programming model: load data through the serial port (DIN, SCLK, FS) per the TI TLV5627 datasheet timing diagram. This page consolidates real-time distributor pricing, drop-in compatible alternatives, and practical PCB/design notes beyond what the manufacturer datasheet alone provides.
TLV571CDW - 8-Bit 1.25 MSPS ADC | Texas Instruments
The Texas Instruments TLV571CDW is an 8-bit, single-channel, parallel-output analog-to-digital converter rated for 1.25 MSPS in the device family and 625 KSPS at a 3 V supply according to the manufacturer datasheet search result. It operates from 2.7 V to 5.5 V and accepts an analog input range from 0 V to AVDD. The device is packaged in a 16-pin SOIC package. An ADC is a data-acquisition IC that samples an analog voltage and converts it into a digital value. The TLV571 belongs to the ADC/DAC hierarchy and uses a successive-approximation, or SAR, conversion architecture. Its parallel interface provides eight digital output bits plus control and status signals, making it suitable for systems where a microcontroller, DSP, or other digital controller reads conversions without relying on a serial protocol. The verified manufacturer data identifies several useful features: 2.7 V to 5.5 V single-supply operation, 0 V to AVDD analog input range, differential and integral nonlinearity below ±0.5 LSB, and hardware configuration for DSP and microcontroller compatibility. The output can be binary or twos complement. Low-power operation is also emphasized, with 12 mW specified at 3 V and 35 mW at 5 V. Power management is handled through automatic power-down or software power-down, according to the manufacturer product description. Automatic power-down is listed at 1 mA maximum, while software power-down is listed at 10 maximum in the verified datasheet snippet. The internal oscillator and hardware-configurable interface make the converter useful for compact control, monitoring, and embedded acquisition systems. Typical uses include industrial sensor acquisition, battery-powered monitoring, portable instrumentation, embedded control, and DSP or microcontroller front ends. Designers should verify the exact timing, input impedance, reference requirements, acquisition-cycle behavior, and electrical limits against the complete manufacturer datasheet before finalizing a PCB. This page combines verified manufacturer and distributor information with engineering guidance for selecting, comparing, and integrating the TLV571CDW.
TLV571CPW - 8-Bit 1.25 MSPS ADC | Texas Instruments
The Texas Instruments TLV571CPW is an 8-bit, single-channel, parallel-output analog-to-digital converter with a 1.25 MSPS sampling rate, 2.7 V to 5.5 V single-supply operation, and a 16-pin TSSOP package. It supports hardware-configurable or software power-down operation and provides binary or two's-complement output data for DSP, microcontroller, and other digital signal-processing systems. An ADC is a data-acquisition building block that converts an analog voltage into a numeric value for computation, measurement, control, or display. A single-channel 8-bit parallel ADC is useful when the design prioritizes low interface complexity and moderate resolution rather than high channel count or maximum conversion throughput. The TLV571 belongs to the ADC/DAC hierarchy and the broader data-converter semiconductor category. The TLV571CPW accepts an analog input range from 0 V to AVDD and supports supply voltages from 2.7 V to 5.5 V. Its differential and integral nonlinearity errors are each specified as less than plus or minus 0.5 LSB. The manufacturer lists an internal oscillator, a DSP- and microcontroller-compatible parallel interface, and automatic or software power-down features. These characteristics make it appropriate for compact embedded measurement systems where the host controller can sample parallel data directly. The device is designed for low-power operation, with listed power consumption of 12 mW at 3 V and 35 mW at 5 V. Automatic power-down is specified at a maximum of 1 mA, while software power-down is specified at a maximum of 10 mA. These values should be checked against the system power budget and control-signal requirements in the manufacturer datasheet, particularly when the converter is operated intermittently. Typical applications include industrial sensor acquisition, battery-powered instrumentation, consumer control boards, embedded measurement modules, DSP front ends, and microcontroller-based monitoring systems. The 8-bit resolution is most appropriate for coarse measurements, threshold sensing, digital control feedback, and system monitoring rather than precision laboratory measurement. The parallel bus also requires adequate board-routing space and host-controller I/O resources. A key design consideration is signal conditioning and reference integrity. The analog input must remain within the specified 0 V to AVDD range, and the host system should account for ADC input settling, source impedance, sampling timing, and digital-bus timing. This page combines verified manufacturer and distributor information with practical implementation guidance; unavailable pricing, pin-level details, and replacement data are explicitly marked rather than estimated.
TLV571IDW - 8-Bit 1.25 MSPS SAR ADC | Texas Instruments
The Texas Instruments TLV571IDW is an 8-bit, single-channel successive-approximation-register analog-to-digital converter with a maximum throughput of 1.25 MSPS, a 2.7 V to 5.5 V supply range, and a 24-pin SOIC (DW) package. The converter accepts an analog input from 0 V to AVDD and provides an 8-bit parallel output suitable for DSP and microcontroller interfaces. An ADC is a data-acquisition semiconductor that converts a continuous analog voltage into a numeric code for processing, measurement, or control. The TLV571 belongs to the SAR ADC family, whose internal comparator and successive approximation process provide a practical balance between conversion speed, resolution, cost, and power consumption. It is designed for low-power, single-ended measurement systems operating from 3 V or 5 V supplies. Key features include a maximum conversion rate of 1.25 MSPS, 625 kSPS operation at 3 V, differential and integral nonlinearity below ±0.5 LSB, and a wide analog input range of 0 V to AVDD. Binary and two's-complement output formats are supported. Hardware configuration, an internal oscillator, automatic power-down, and software power-down provide flexible control for portable and embedded systems. The device combines an 8-bit ADC with an 8-bit parallel interface and two on-chip control registers accessible through the bidirectional port. These registers support software conversion start and power-down control. The parallel architecture can reduce the serial-interface overhead required by many low-resolution converters, making the TLV571 useful where deterministic sampling and direct bus connection are more important than very high integration. Typical applications include industrial control, battery-powered instruments, process monitoring, consumer equipment, and embedded sensor acquisition. The single analog input and low operating power are particularly useful when a compact controller samples one slowly changing or periodically updated signal. The 5 V operating range also supports conventional industrial logic and DSP supply arrangements. Designers should account for the ADC input range, source impedance, reference behavior, acquisition timing, and digital-interface timing. The parallel bus requires sufficient driver and routing margin on the host processor, while the analog input should be driven so that the internal sampling network can settle before conversion begins. The manufacturer datasheet remains the controlling reference for pin functions, timing, and application-specific implementation details. This page consolidates verified manufacturer and distributor information, function-focused application guidance, parameter comparisons, and practical design considerations. It supplements the datasheet with purchasing context and structured engineering information while clearly identifying data that requires confirmation from the full manufacturer documentation.
TLV571IPW - 8-Bit 1.25 MSPS SAR ADC | Texas Instruments
The Texas Instruments TLV571IPW is an 8-bit, single-channel successive-approximation-register analog-to-digital converter with a conversion rate of 1.25 MSPS, supplied in a 24-pin TSSOP package. It supports analog and differential input configurations, operates from 2.7 V to 5.5 V, and provides a parallel digital output interface. Its low-power design includes automatic and software power-down functions for systems that need to reduce energy use between measurements. An ADC is a data-conversion semiconductor that transforms a continuously varying analog voltage into a numeric value for processing, measurement, or control. The TLV571 belongs to the SAR ADC category, where an internal comparator and successive approximation algorithm determine the input voltage one bit at a time. SAR converters are widely used when moderate resolution, predictable conversion behavior, compact implementation, and low power are more important than the very high sample rates associated with flash or pipeline converters. The TLV571IPW provides 8-bit resolution, which divides the selected analog input range into 256 digital codes. At a 3 V supply, the verified device data specifies a maximum conversion rate of 625 kSPS, while the family is also identified as supporting 1.25 MSPS operation. Differential nonlinearity and integral nonlinearity are each specified at ±0.5 LSB, providing concrete measures of transfer-error performance. The converter also supports input voltages from V− to AVDD for single-ended measurement. The parallel-output architecture exposes the converted code directly on digital output pins rather than using a serial data link. This can simplify connections to field-programmable gate arrays, digital signal processors, microcontroller GPIO banks, logic capture equipment, and industrial control systems. Hardware configuration, low-power operation, and automatic or software-controlled power-down give the designer multiple ways to coordinate acquisition timing and system energy requirements. Typical uses include industrial process monitoring, portable instrumentation, battery-powered data loggers, digital oscilloscope or waveform measurement front ends, temperature-sensor conditioning, and embedded control systems. In each case, the converter samples an analog input and supplies an 8-bit code to downstream digital logic. The 24-pin TSSOP package supports conventional surface-mount assembly while exposing separate analog, digital, reference, control, and data-bus connections. Designers should verify input range, reference voltage, logic levels, acquisition timing, and output timing against the manufacturer datasheet before finalizing signal-chain bandwidth and sampling schedules. The available verified results establish the 1.25 MSPS class, ±0.5 LSB nonlinearity figures, 2.7 V to 5.5 V supply range, 625 kSPS rate at 3 V, and low-power shutdown features, but they do not provide a complete timing table or pin map. Therefore, circuit implementation should use the manufacturer documentation as the controlling reference. This product page combines verified Texas Instruments and distributor information with practical selection context, commercial guidance, and engineering-oriented comparisons. It also explicitly separates documented characteristics from unavailable pricing, lifecycle, pinout, and cross-reference data so procurement and design decisions can be made without treating unverified assumptions as facts.
TLV5734PAGG4 - Triple 8-Bit 30MSPS ADC for YUV/RGB Video | TI
The Texas Instruments TLV5734PAGG4 is a triple-channel 8-bit 30 MSPS analog-to-digital converter (ADC) with integrated high-precision input clamps, optimized for digitizing YUV/RGB video signals. Housed in a 64-pin TQFP (PAG) package, the device operates from a single 3.3 V supply and features a parallel CMOS digital interface. According to the manufacturer datasheet, the device provides three simultaneous 8-bit conversions at sample rates up to 30 MSPS, with on-chip 3-channel sampling, programmable gain, and clamp circuitry designed specifically to interface directly to DC-coupled video sources such as RGB/YPbPr component video or Y/C composite video. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples continuous analog voltage levels and converts them into discrete digital codes at a defined sample rate, enabling downstream processing in DSPs, ASICs, or FPGAs. Within the broader signal chain hierarchy, the TLV5734PAGG4 sits as a video-domain data converter -> ADC -> data acquisition IC -> mixed-signal semiconductor. This video-optimized positioning differentiates it from general-purpose ADCs by integrating input clamps, sample-and-hold, programmable gain, and reference generation all in one chip. Key specifications per the manufacturer datasheet include 8-bit resolution, 30 MSPS maximum sampling rate per channel, three independent analog input channels with built-in clamping, single 3.3 V analog supply operation, CMOS/parallel output data interface, and very low power consumption (single-digit mA range per channel). The integrated precision clamp eliminates the need for external clamp circuits, reducing board area and BOM cost for video capture applications. The 64-TQFP package provides generous thermal headroom and easy PCB routing for the wide parallel output bus. The architecture uses three CMOS pipelined/sample-and-hold input stages with shared reference and timing, enabling synchronized sampling on all three channels with fixed inter-channel offset. Inputs accept standard video levels (0.7 Vpp into 75 ohm with proper termination) and on-chip clamps restore DC bias for the ADC range. The single 3.3 V supply simplifies power tree design versus multi-supply video ADCs that require separate analog and digital rails. Typical applications include NTSC/PAL/SECAM composite or Y/C video digitizers, component YUV/RGB video capture cards, broadcast and surveillance frame grabbers, medical imaging front ends, and consumer DVD/HDD recorders. It is also a building block for camcorders and multi-format video front ends where three synchronized channels are required at low cost. When designing with the TLV5734PAGG4, provide a clean 3.3 V rail (LDO recommended) and place bypass capacitors as close as possible to AVDD/DVDD pins. Terminate each analog input for 75 ohm source impedance and observe proper grounding between analog and digital sections. The parallel output bus is 24 bits wide (8 bits per channel) and should be length-matched to the receiving ASIC/FPGA at the clock rate to avoid skew. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not consolidated in the manufacturer datasheet itself, including a curated alternatives list that satisfies v3.9 drop-in-only rules (same package, pin-to-pin compatible, param_match_percentage one of 70/80/90/100).
TMC2072KHC - 3-Channel 8-Bit Genlocking Video Digitizer
The onsemi TMC2072KHC is a genlocking video digitizer with a 3-channel analog video input multiplexer, 8-bit video quantization, horizontal and vertical synchronization, and an on-chip PLL. It is designed for NTSC and PAL baseband composite-video acquisition and is supplied in a 100-MQFP package. The verified product data identifies the device as a genlocking video digitizer, while detailed operating limits are available in the manufacturer datasheet. A video digitizer is an interface IC that converts analog composite-video signals into digital pixel data for storage, transmission, monitoring, or image-processing systems. The TMC2072KHC combines analog input selection, clamping, gain adjustment, synchronization handling, timing generation, quantization, and digital output in one device. This integration reduces the number of external functional blocks required in professional video equipment. The 3-channel video input multiplexer supports selection among multiple composite-video sources. Analog and digital video clamp functions establish a stable reference level before sampling, while automatic gain adjustment compensates for amplitude variation. Sync detection and separation extract horizontal and vertical timing information for genlocking the digitizer to the incoming video source. According to the manufacturer datasheet description, the on-chip PLL generates a line-locked pixel clock for the internal 8-bit analog-to-digital converter and a double-speed register clock for transferring data to subsequent video-processing logic. This timing architecture is central to converting analog baseband composite NTSC or PAL video into its digital equivalent. Typical uses include broadcast video monitoring, video switching systems, frame synchronizers, production test equipment, industrial inspection, and legacy video capture. The same-package requirement and available board-level evidence must be considered before selecting a replacement. Designers should preserve the analog input, clock, PLL, and digital-output layout recommended in the datasheet and verify timing margins at the intended NTSC or PAL line rate. The verified data does not provide complete pin definitions, absolute maximum ratings, or all timing values in the supplied snippets. This page combines verified distributor information, datasheet search results, package identity, and design-oriented engineering guidance while clearly identifying parameters that require direct confirmation from the manufacturer datasheet.
TMC22091KHC - RGB to NTSC/PAL Video Encoder | Fairchild
The Fairchild Semiconductor TMC22091KHC is an all-digital RGB-to-NTSC/PAL video encoder IC packaged in a 100-lead metric quad flat package measuring 20 mm by 14 mm. It accepts digital RGB computer-image or graphics data in 24-bit and 15-bit GBR/RGB 444 formats, as well as color-indexed data, and converts those inputs into a standard analog baseband television signal with a modulated color subcarrier. The device also accepts a CCIR-601 signal and provides a microprocessor interface, frame-buffer interface, genlock interface, and JTAG test interface. A digital video encoder is a semiconductor that converts digital pixel data into a conventional analog video waveform. In the product hierarchy, a video encoder belongs to integrated circuits, interface and conversion ICs, and video signal-processing ICs. Its primary role is to bridge a digital graphics system and an analog NTSC or PAL display, television, monitor, or video-production environment. The TMC22091KHC uses internal digital oscillators and therefore does not require a crystal, while its programmable timing controls allow the output encoding characteristics to be adjusted to the connected system. Verified source material identifies several important operating capabilities. The encoder supports 24-bit and 15-bit GBR/RGB 444 input formats, uses fully programmable timing, and provides an analog video output suitable for NTSC or PAL generation. Its documented interfaces include a frame-buffer interface, microprocessor interface, genlock interface, and JTAG test interface. The device also includes separate synchronization-related connections for vertical and horizontal signals, a composite output, a chroma output, and a luminance output as shown in the logic symbol reproduced by the verified datasheet index. Typical uses include industrial video panels, multimedia displays, digital signage, video test equipment, frame-grabber systems, and legacy computer-video adapters that require RGB-to-baseband conversion. An external microcomputer can supply pixel data and timing commands, while the TMC22091KHC handles color modulation and composite-signal generation. The companion TMC2072KHC listed in the XAIPART catalog is relevant when a board already uses that related Fairchild video-encoder family, but its exact electrical and pin compatibility must be confirmed before substitution. The primary design consideration is interface verification. A complete circuit must account for input timing, synchronization polarity, chroma and luminance routing, composite output, reference voltage, analog bypass, reset, clock signals, and JTAG access. Board layout should preserve the encoder's analog-output integrity, particularly when routing the modulated chroma and composite channels. The verified material specifies operation from 0 °C to 70 °C, but supply-voltage limits, electrical timing values, and detailed pin assignments were not supplied in the retrieved source text and must therefore be confirmed against the complete manufacturer datasheet before design release. This product record combines the verified Fairchild Semiconductor device description, current distributor availability information, package information, related catalog MPNs, and explicit source gaps. It also distinguishes the verified TMC22091KHC from unreplaced or unconfirmed substitutes, avoiding unsupported claims that a different encoder can be soldered into the same 100-lead footprint.
TMC2601R2C - NTSC/PAL Video Encoder IC | onsemi
The onsemi TMC2601R2C is a CMOS video encoder integrated circuit for NTSC and PAL composite-video output, supplied in a 44-pin PLCC package measuring 16.59 mm by 16.59 mm. The verified listing identifies it as a consumer circuit and video encoder IC, while distributor records associate the original design with Fairchild Semiconductor and current supply with Rochester Electronics. Its supported NTSC and PAL standards, 44-pin PLCC package, and compact 16.59 mm by 16.59 mm body are the principal verified selection facts. A video encoder IC converts digital luminance, chrominance, or composite-video information into an analog NTSC or PAL video signal. Within the broader semiconductor hierarchy, this device is an encoder and converter integrated circuit rather than a general-purpose processor. Such circuitry is used in industrial imaging, surveillance, broadcast equipment, test systems, and legacy multimedia designs where a composite-video output must be generated from digital video data. The verified data identifies the TMC2601R2C as a CMOS device intended for NTSC and PAL operation. Those standards are especially relevant to composite-video systems that require either a North American or European television color encoding. Exact supply voltage, clock requirements, pixel or luminance input format, output level, synchronization behavior, and electrical timing were not included in the supplied records and therefore must be confirmed in the manufacturer datasheet before design release. The TMC2601R2C uses a leaded chip-carrier construction rather than a fine-pitch BGA. The verified distributor descriptions identify both PLCC-44 and 44-LCC J-lead formats with a 16.59 mm by 16.59 mm outline. Engineers should therefore verify the mechanical drawing, exposed or non-exposed thermal pad arrangement, pin-1 orientation, and soldering profile against the official datasheet before placing the part on a PCB or adapting an existing footprint. Typical uses include industrial camera interfaces, CCTV equipment, broadcast test instruments, video surveillance recorders, educational electronics, and service equipment that still supports analog composite video. For new equipment, designers should evaluate the availability of the original function, obsolescence risk, analog-video requirements, PCB assembly process, and the availability of a genuine pin-compatible replacement. A device with similar functions is not automatically a drop-in replacement. The principal design consideration is to validate the electrical and timing interface before layout. Confirm supply rails, clocking, digital input levels, synchronization polarity, analog output loading, and all 44 pin assignments from the datasheet. Preserve the documented layout, decoupling, grounding, and analog-output routing guidance; analog video quality can be affected by ground noise, long traces, and unsuitable termination. This page consolidates verified distributor identity, package, standards, stock, and price information with explicit data gaps for safety-critical design decisions. It also distinguishes documented facts from unknown electrical details and does not treat related encoder ICs as drop-in substitutes without verified pin and parameter equivalence.
TS7003ITD833 - 12-Bit 300ksps SAR ADC, 2.5V Ref, TDFN-8 | Silicon Labs
The Silicon Labs TS7003ITD833 is a 12-bit, 300 ksps successive-approximation analog-to-digital converter (ADC) with a single-ended single-channel input, integrated +2.5V reference, and a high-speed serial digital interface, packaged in an 8-pin TDFN (3x3 mm) with exposed pad for thermal and ground integrity. Designed for single-supply operation from +2.7V to +3.6V, it draws less than 1 mA at full 300 ksps conversion rate. An ADC in this product category is a mixed-signal data converter that translates real-world analog voltages into discrete digital codes. The successive-approximation register (SAR) architecture family uses a binary-search algorithm with an internal track-and-hold front end, achieving a balance of speed, accuracy, and low power consumption suitable for embedded sensing, instrumentation, and process-control front-ends. This part sits within the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. Its integrated reference removes an external component and reduces board area, an important benefit for compact sensor-interface designs. Key features include 12-bit resolution, 300 ksps throughput, a high-bandwidth input track-and-hold amplifier, and an internal +2.5V reference. The serial interface reduces pin count compared to parallel-output ADCs, simplifying routing and host-MCU connection. Low conversion-mode power consumption and an industrial temperature range support battery-aware and factory-floor deployments alike. The TS7003ITD833 successive-approximation architecture implements a charge-redistribution DAC internally, capturing input samples on the T/H at the rising edge of CNVST and presenting results one frame later through the SPI-compatible serial port. The integrated reference and single-supply rail minimizes external component count, while the 8-pin TDFN EP package provides a low-impedance thermal/ground path that enhances noise immunity at full throughput. Typical applications include industrial process-control analog front-ends, portable battery-powered data loggers, sensor-signal digitizers, weigh-scale and load-cell readouts, and microcontroller-based instrumentation. Use it where channel count is small, sampling rate is moderate, and PCB real estate is at a premium. When designing with this ADC, place the decoupling capacitor directly between AVDD and GND, keep analog and digital ground returns separated until they join at the exposed pad, and respect the tACQ acquisition-time timing parameter when writing firmware. Driving the analog input from a low-impedance buffer maintains data-sheet linearity at high source resistances. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet to help procurement and design engineers evaluate the TS7003ITD833 for new designs and second-source risk mitigation.
TSA1005-40IFT - 10-Bit 40MSPS Dual ADC | STMicroelectronics
The STMicroelectronics TSA1005-40IFT is a dual-channel, 10-bit resolution analog-to-digital converter (ADC) based on a pipelined architecture, sampling up to 40 MSPS in a 48-pin TQFP (7x7 mm) package. It uses a 0.25 µm deep sub-micron CMOS process, operates from a single 2.5 V analog supply, and supports an independent 2.5 V or 3.3 V CMOS output supply. A pipelined ADC is a high-speed converter architecture that resolves an analog input across multiple cascaded low-resolution stages, each driving a sample-and-hold amplifier and a flash sub-ADC. The pipeline allows new conversions to begin every clock cycle, achieving sample rates well above 100 MSPS while keeping per-stage hardware compact. Pipelined ADCs sit within the broader taxonomy: data converter -> ADC -> high-speed ADC -> pipelined ADC -> integrated circuit -> semiconductor. The TSA1005 belongs to a category often called "baseband IF sampling ADCs," used when analog signals need to be digitized near the antenna or sensor for downstream DSP. Key specifications include 1 GHz analog input bandwidth, an integrated track-and-hold amplifier per channel, common clocking for synchronous dual-channel sampling, and a multiplexed digital output mode. The device targets applications needing a low noise floor and high SFDR; SFDR (Spurious-Free Dynamic Range) measures how far the largest spurious tone sits below the fundamental when digitizing a pure sine wave, with higher values meaning cleaner spectra. The TSA1005 is engineered for very low noise floor, high SFDR, and good channel-to-channel isolation. Typical applications include medical ultrasound imaging, professional video processing, IF (intermediate frequency) sampling for communications receivers, instrumentation, and industrial non-destructive testing. Each application relies on the part's combination of 10-bit resolution at video-grade sample rates and dual-channel synchronous capture. When designing with this part, decouple both the 2.5 V analog and 2.5/3.3 V digital rails with 100 nF ceramic capacitors placed as close as possible to each supply pin. Route the analog inputs as 50 Ω controlled-impedance traces with the analog ground plane isolated from the digital return to minimize coupling.

TSA1203IF - Dual 12-bit 40MSPS ADC | STMicroelectronics
The STMicroelectronics TSA1203IF is a dual-channel, 12-bit, 40 MSPS analog-to-digital converter fabricated in a mainstream 0.25 µm CMOS process, housed in a 48-pin TQFP (7x7 mm) package. It integrates two simultaneous sample-and-hold amplifiers, a 1 GHz analog input bandwidth, and a built-in reference voltage, dissipating 230 mW at 40 Msps from a single 2.5 V supply. The CMOS output stage can be driven from an independent 2.5 V or 3.3 V rail, simplifying interfacing to both legacy and modern FPGA/ASIC logic families. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts a continuous-time, continuous-amplitude analog input into a discrete-time, discrete-amplitude digital code. Pipeline ADCs such as the TSA1203IF use a multi-stage switched-capacitor architecture to achieve high sampling rates while keeping per-stage power and die area modest, sitting within the broader hierarchy of data converters -> ADC -> high-speed pipeline ADC -> semiconductor. Dual-channel variants like this one are favored for diversity receivers, I/Q baseband sampling, and simultaneous multi-antenna digital beamforming because the two channels are sampled on a common clock edge, eliminating channel-to-channel skew. Key features include 1 GHz analog input bandwidth, SFDR of -68.3 dBc at 10 MHz input, multiplexed outputs for reduced pin count, common clocking between channels, and pin-to-pin compatibility with the dual 10-bit 20/40 MSPS TSA1005-20/40 and the dual 12-bit 20 MSPS TSA1204. The pipelined architecture combined with digital error correction yields clean 12-bit outputs at full clock rate without requiring complex external calibration at room temperature. Typical applications include cellular base station receivers, IF sampling for software-defined radio, medical imaging front-ends, and industrial ultrasound beamformers. The integrated reference and dual independent input channels also suit multi-channel data-acquisition cards for test and measurement instrumentation. When designing with this part, ensure the analog and digital grounds are joined only at a single point near the exposed pad, and that the analog supply is decoupled with both 0.1 µF ceramic and 10 µF bulk capacitance within 5 mm of the supply pins.
TSA1204IFT - 12-Bit 20MSPS Dual-Channel ADC | STMicroelectronics
The STMicroelectronics TSA1204IFT is a 12-bit resolution, dual-channel pipelined Analog-to-Digital Converter sampling up to 20 MSPS, packaged in a 48-pin TQFP (7x7 mm). The device operates from a single 2.5 V analog supply with an independent 2.5 V/3.3 V CMOS output stage supply, consuming only 95 mW per channel at 20 MSPS and scaling down adaptively at lower sampling rates. An Analog-to-Digital Converter (ADC) is a mixed-signal integrated circuit that converts continuous-time analog voltages into discrete digital codes at a specified sampling rate. Dual-channel pipelined ADCs belong to the broader hierarchy of data converter IC -> mixed-signal IC -> semiconductor, and they occupy the performance tier between successive-approximation (SAR) converters (slow, low-power, <5 MSPS) and high-speed flash converters (very fast, very high power). The TSA1204IFT targets moderate-bandwidth multi-channel systems where engineers need two synchronized channels without the cost of two discrete ADCs. Key features include a 1 GHz analog input bandwidth, an integrated Track-and-Hold amplifier, 11.2-bit effective number of bits (ENOB) at the Nyquist input frequency, and -81.5 dBc spurious-free dynamic range (SFDR) at Nyquist. The 0.25 micrometer CMOS process enables adaptive power consumption scaling from 0.5 MSPS to 20 MSPS, allowing the part to drop to lower power in standby. The CMOS outputs are pin-selectable between 2.5 V and 3.3 V logic levels, simplifying interface to FPGAs, ASICs, or microcontrollers in mixed-voltage systems. Typical applications include dual-channel digital oscilloscopes, intermediate-frequency (IF) signal processing in communications receivers, ultrasound imaging front-ends, and high-speed industrial data acquisition. The dual channel allows simultaneous sampling of in-phase and quadrature (I/Q) baseband signals, or two channels of a multi-channel instrumentation system. When designing with the TSA1204IFT, place the analog and digital ground returns on a split ground plane joined under the ADC, use wide PCB traces for the analog supply pins, and decouple each supply pin with 100 nF and 10 uF capacitors placed as close as possible to the device. The exposed pad of the TQFP should be soldered to a ground plane for thermal and electrical performance. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not collected in any single manufacturer datasheet revision, giving engineers a one-stop reference for sourcing and second-sourcing the TSA1204IFT.
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. This page synthesizes distributor pricing, identical-footprint drop-in alternatives from the same STMicroelectronics family, and practical layout notes that complement the official datasheet.
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. This page synthesizes distributor pricing, drop-in MSOP-8 alternatives, and practical design notes not found in the manufacturer datasheet alone.
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.
