ADC1613S125HN-C1 - 16-bit 125 MSPS JESD204A ADC | Renesas
The Renesas ADC1613S125HN-C1 is a single-channel, 16-bit pipelined analog-to-digital converter (ADC) optimized for high dynamic performance and low power at sample rates up to 125 MSPS. It is housed in a 32-pin HVQFN (SOT1152-1, 7x7 mm, 0.80 mm height) package with exposed pad and supports a JESD204A serial output interface. The -C1 ordering suffix denotes the standard industrial screening level per Renesas' product family convention. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that samples continuous analog input signals and converts them into discrete digital codes. The pipelined ADC architecture used in the ADC1613S125HN-C1 cascades multiple low-resolution flash stages with inter-stage sample-and-hold and digital error correction, achieving a practical balance between conversion speed (tens to hundreds of MSPS) and resolution (12-16 bits). Pipelined ADCs sit within the broader data-converter hierarchy alongside successive-approximation (SAR) and delta-sigma converters, and are the dominant choice for high-speed IF/baseband digitisation in communications, instrumentation, and imaging. Key features of the ADC1613S125HN-C1 include a 16-bit resolution, 125 MSPS maximum sampling rate (with speed grades also available at 65, 80, and 105 MSPS in the same family), a JESD204A serial output interface that simplifies board routing and reduces pin count compared to parallel LVDS, and a single 1-channel differential/single-ended analog input. The HVQFN-32 package provides a low thermal-resistance path through the exposed pad, and the part is specified over the -40 to +85 C industrial temperature range. From an architectural standpoint, the device uses a differential pipeline core followed by on-chip digital processing and a JESD204A link-layer transmitter, enabling deterministic multi-converter synchronization and a single high-speed serial differential pair rather than 16 parallel data lines. This makes the ADC1613S125HN-C1 particularly attractive in space-limited multi-channel systems where dozens of LVDS traces would otherwise consume PCB area. Typical applications include wireless base-station receive chains, radar and LiDAR signal digitisation, medical imaging front-ends (ultrasound beamformers), high-speed data acquisition for test and measurement, and software-defined radio (SDR) platforms. The JESD204A interface also lets multiple ADCs share a single FPGA/ASIC receiver, simplifying multi-antenna MIMO receiver designs. A key design consideration is that the JESD204A link must be initialised and frame-locked before valid conversions are emitted, which requires correct SYSREF, device clock, and reference-clock distribution. PCB designers should route the JESD204A serial differential pair with 100 ohm differential impedance and place the device on a solid ground plane with low-noise LDO supplies for the analog AVDD rail. This page synthesises distributor pricing, drop-in alternatives, and practical design notes drawn from Renesas datasheets and the cross-brand data acquisition ecosystem, providing engineering context beyond the manufacturer's datasheet alone.
ADC1613S125HN-C18 - 16-Bit 125 MSPS Single-Channel ADC | Renesas
The Renesas ADC1613S125HN-C18 is a single-channel, 16-bit pipelined analog-to-digital converter (ADC) optimized for high dynamic performance and low power at sample rates up to 125 MSPS. The device uses a JESD204A serial output interface and is housed in a 32-pin HVQFN package with exposed thermal pad. Key specifications include 16-bit resolution, 125 MSPS sampling rate, single analog input channel, low-latency pipelined architecture, and serial LVDS compliant output data transport. This ADC belongs to the pipelined ADC family, which is the dominant converter architecture for high-speed signal capture in communications, radar, and instrumentation. Pipelined ADCs digitize an input signal by cascading low-resolution stage ADCs with residue amplifiers and DACs, achieving high sample rates while maintaining 14-16 bits of resolution with low latency between convert and output. Pipelined ADCs sit hierarchically under high-speed ADC -> data converter -> signal chain IC -> semiconductor, and they typically outperform successive-approximation-register (SAR) ADCs beyond about 10 MSPS. Key features include a 16-bit output word, a differential analog input, a separate analog and digital supply for noise isolation, an internal reference option with external override capability, and dithering for improved SFDR at small input signals. The JESD204A interface reduces board routing complexity by serializing the data onto a single LVDS pair, but it requires a JESD204A-compliant FPGA or ASIC receiver to deserialize the data into sample-aligned words. Technically, the ADC1613S125HN-C18 uses multi-stage switched-capacitor pipeline stages clocked by an internal PLL, with digital error correction in the final stage. Its reported SNR performance rivals Sigma-Delta converters of similar bandwidth while its power consumption remains moderate for a 125 MSPS 16-bit pipelined part. The HVQFN-32 package provides a low thermal resistance path so the device can sustain high sample rates without thermal throttling. Typical applications include multi-carrier GSM/EDGE/WCDMA/LTE base-station receivers, radar digitizers, medical imaging front-ends, cable modem downstream capture, and high-end test and measurement equipment. The combination of 16-bit resolution, 125 MSPS sampling, and JESD204A serial output makes it suited to systems requiring high dynamic range over wide IF bandwidths. When designing with this part, verify that the host FPGA supports JESD204A (not only JESD204B/C) before prototyping, and ensure the JESD204A subclass 0 deterministic latency requirements are met by sharing the device clock between ADC and FPGA. The exposed thermal pad must be soldered to a continuous ground copper plane for heat extraction and ground reference.

ADC31JB68RTA25 - 16-Bit 500-MSPS JESD204B ADC | Texas Instruments
The Texas Instruments ADC31JB68RTA25 is a 16-bit, 500-MSPS, single-channel pipelined analog-to-digital converter that outputs data over a JESD204B serial interface, housed in a 40-pin WQFN (6x6 mm) package with an exposed thermal pad. It pairs a buffered analog input with a 1.3 GHz analog input bandwidth, operates from a 1.2 V supply, and consumes low power while delivering high SFDR for wideband signal chains. According to TI product literature, this device samples input signals up to 1300 MHz while preserving spurious-free dynamic range (SFDR). An ADC (analog-to-digital converter) is a data converter IC that translates continuous-time analog signals into discrete digital codes for downstream DSP, FPGA, or ASIC processing. Pipelined ADCs use a cascade of low-resolution flash stages to achieve high sample rates at high resolution; the ADC31JB68 specifically belongs to the high-speed pipelined converter family with an integrated JESD204B serializer. In the broader taxonomy it sits under: ADC -> data converter -> mixed-signal IC -> power management and signal chain IC -> semiconductor. Key features include 16-bit resolution, 500 MSPS maximum sampling rate, JESD204B subclass 0/1 compliant output up to 5 Gbps lane rate, buffered analog input with uniform input impedance, low sample-and-hold glitch energy, integrated clock divider, and a wideband front end designed for IF/RF sampling. The WQFN-40 package with exposed thermal pad reduces theta_JA and supports sustained 500 MSPS operation without aggressive external heatsinking. The ADC31JB68 uses a multi-stage pipelined architecture with proprietary linearity calibration, an internal high-bandwidth track-and-hold, and a JESD204B link layer that supports one or two lanes with deterministic latency and up to 8b/10b encoding for DC-balanced serial transmission. This architecture gives designers flexibility in FPGA/ASIC SerDes selection while simplifying board-level routing relative to LVDS interfaces. Typical applications include wideband communications receivers, radar and electronic-warfare signal chains, test and measurement instrumentation (spectrum analyzers, oscilloscopes), software-defined radio (SDR) platforms, cable head-end DOCSIS 3.1 digitizers, and medical imaging front ends such as ultrasound beamformers. The 1.3 GHz input bandwidth enables direct IF sampling without an external mixer in many architectures. When designing with this device, allocate sufficient PCB layer count and controlled-impedance routing for the JESD204B lanes; pair the part with a low-jitter clock source such as the LMK04821 family referenced in TI's reference designs.
ADC3223IRGZ25 - Dual 12-Bit 80MSPS Low-Power ADC | Texas Instruments
The Texas Instruments ADC3223IRGZ25 is a dual-channel, 12-bit, 80-MSPS analog-to-digital converter from the ADC3x family, housed in a 48-pin VQFN (RGZ) package measuring 7x7 mm. It features pipelined architecture with LVDS/serial digital outputs, ultra-low power consumption, and high linearity for communications, industrial imaging, and radar signal chain applications. A pipelined ADC is a high-speed analog-to-digital converter that resolves an analog input by cascading low-resolution flash stages with digital error correction and inter-stage residue gain. Each stage samples and holds the input, performs a coarse quantization, and passes an amplified residue to the next stage; the final code is assembled from the per-stage decisions plus latency. This architecture dominates the 10 MSPS to 500 MSPS performance window because it scales resolution, speed, and power much more favorably than flash or SAR converters. Within the power-management hierarchy, the ADC sits at the analog front-end -> data converter -> signal chain layer of mixed-signal ICs. Key features of the ADC3223IRGZ25 include dual simultaneous-sampling 12-bit channels, an 80 MSPS sample rate, LVDS and serial CMOS interface options, integrated low-jitter clock buffer, and programmable gain. The device operates from a single 1.8 V supply and from -40C to +85C industrial temperature range. Its pipelined core delivers high spurious-free dynamic range while keeping total power below competing dual-channel ADCs in the same MSPS class. The ADC3223 uses a switched-capacitor pipelined front-end with on-chip reference, digital calibration, and selectable output formats. The 12-bit -Q1 suffix indicates 25 MSPS operation within the broader ADC32xx family; the underlying silicon supports up to 80 MSPS at higher -speed grades. LVDS outputs minimize EMI for backplane and board-to-board digital links while CMOS serial mode simplifies low-pin-count FPGA/CPU capture. Typical applications include communications base-station IF digitization, portable and handheld instrumentation, ultrasound beamforming front-ends, multi-channel industrial data acquisition, and radar/LiDAR front-end digitizers. The dual-channel + low-power combination is especially attractive for handheld ultrasound probes where channel count and battery life both matter. When designing with this part, decouple AVDD/DVDD with low-ESR 0.1uF plus 10uF capacitors placed within 5 mm of each supply pin, and keep the analog input traces impedance-matched to 50 ohms with a balun if driven single-ended. The internal reference can be bypassed with a 10uF cap at REFM/REFP to minimize kick-back noise at high sample rates.
ADC3224IRGZ25 - Dual 12-Bit 125MSPS Low-Power ADC | TI
The Texas Instruments ADC3224IRGZ25 is a dual-channel, 12-bit, 125-MSPS pipelined analog-to-digital converter housed in a 48-pin VQFN (7x7 mm) package. It is part of TI's ADC3x family of high-linearity, ultra-low-power ADCs, with member datasheets covering 12/14-bit resolutions at 25 to 125 MSPS sample rates. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples continuous-time analog voltage at its input and produces a discrete-time digital code word at its output. The converter is the critical bridge between the analog domain (sensors, RF front-ends, audio, instrumentation) and the digital processing domain (FPGAs, ASICs, DSPs). Within the broader taxonomy, the ADC3224 belongs to the pipelined ADC class, which sits between high-speed flash ADCs and high-resolution sigma-delta ADCs in the speed/resolution trade-off. Pipelined ADCs are favored in communications, IF sampling, multi-channel data acquisition, and portable test equipment because of their ability to digitize tens to hundreds of MHz of analog bandwidth at low per-channel power. Key features of the ADC3224IRGZ25 include a 1.8 V single supply, SNR of 70.2 dBFS at fIN = 70 MHz, SFDR of 87 dBc at the same input frequency, channel isolation of 105 dB, ultra-low power consumption of 116 mW per channel at 125 MSPS, a Serial LVDS (SLVDS) digital interface, a flexible input clock buffer with divide-by-1, -2, -4 options, internal dither, internal chopper, and multi-chip synchronization support. Architecturally, the device uses a multi-stage pipelined core with digital error correction, integrated input buffer / SHA, on-chip voltage reference, and an SLVDS serializer for low-EMI digital output. The 105 dB channel isolation enables two independent IF sampling channels to share one chip with minimal crosstalk. Typical applications include communications base-station IF sampling, multi-carrier software-defined radio receivers, portable battery-powered test and measurement, medical imaging front-ends, and dual-channel industrial data-acquisition systems. The pin-to-pin compatibility with the 14-bit ADC3224 family allows drop-in resolution upgrade or downgrade without PCB rework. When designing with this ADC, ensure the analog input network and the SLVDS output trace lengths are matched for sub-nyquist operation. Decoupling the 1.8 V AVDD and 1.8 V DVDD rails close to the device is critical, because the 116 mW/channel dissipation scales with sampling rate and input frequency.

ADC3241IRGZ25 - Dual 14-Bit 25MSPS ADC | Texas Instruments
The Texas Instruments ADC3241IRGZ25 is a dual-channel, 14-bit, 25-MSPS analog-to-digital converter (ADC) housed in a 48-pin VQFN (RGZ) 7x7 mm package. Built on TI's proprietary pipeline architecture, it delivers 72.4 dBFS SNR and 87 dBc SFDR at a 70 MHz input frequency while consuming only 116 mW per channel. A wide 105 dB channel-to-channel isolation figure makes the part well suited to time-interleaved or diversity receiver front-ends. An analog-to-digital converter (ADC) is a mixed-signal semiconductor that samples a continuous-time analog voltage and encodes its amplitude into a discrete digital word. Pipeline ADCs like the ADC3241 sit at the high-performance end of this category, using a multi-stage switched-capacitor architecture combined with digital error correction. They are commonly grouped under the broader hierarchy of data-conversion ICs and ultimately fall within the wider mixed-signal and power-management IC ecosystem used by virtually every modern digital signal chain. Key differentiating features of the ADC3241 include a flexible input clock buffer that supports divide-by-1, -2, and -4 ratios, ultra-low power consumption of 116 mW per channel at 125 MSPS operation, and a serial LVDS (SLVDS) data interface that minimizes digital coupling into the analog chain. The internal aperture delay, tracking bandwidth, and calibrated gain/offset are designed for deterministic latency, which simplifies multi-channel synchronization in digital pre-distortion, radar, and beamforming systems. Typical applications include communications base-station receivers, multi-carrier software-defined radio (SDR) platforms, industrial imaging front-ends, ultrasound signal processing, and portable instrumentation. The low latency and high channel density also suit time-of-flight and LiDAR digitizer designs that must digitize multiple return pulses with tightly aligned sampling instants. When designing a board with this part, follow standard high-speed mixed-signal layout practice. Decouple the AVDD and DVDD rails with low-ESL ceramics placed as close as possible to the supply pins, and separate the analog and digital ground planes with a single stitching point placed under the exposed thermal pad. Maintain a clean, impedance-controlled LVDS routing on the DOUT pins to preserve the rated SNR and SFDR.

ADC3242IRGZ25 - Dual 14-Bit 50MSPS ADC | Texas Instruments
The Texas Instruments ADC3242IRGZ25 is a dual-channel, 14-bit, 50-MSPS analog-to-digital converter from the ADC3x family, housed in a 48-pin VQFN (7x7 mm) package. It combines high linearity, ultra-low power consumption, and a pipelined architecture, making it well suited to multi-channel communications, ultrasound, and portable instrumentation front-ends. The '25' speed grade denotes 50 MSPS operation, while the 'RGZ' suffix marks the QFN package and '25' reel-packaging code as ordered on the full reel. An analog-to-digital converter (ADC) is a data-conversion integrated circuit that samples a continuous-time, continuous-amplitude analog input and produces a discrete-time, discrete-amplitude digital output. Within the broader data-converter hierarchy, the ADC3242 belongs to the pipelined-ADC sub-class, which sits between precision successive-approximation (SAR) ADCs (used at low sample rates) and high-speed flash / folding ADCs (used at GHz rates). As a power-management-aware pipeline ADC, the ADC3242 delivers 14-bit resolution at sample rates up to 50 MSPS with significantly lower power than older 14-bit pipelines, placing it in the 'mid-rate precision pipeline' category used in LTE base-station observation paths, multi-carrier GSM receivers, and medical imaging AFE front-ends. Key features of the ADC3242IRGZ25 include 70.7 dBFS SNR at 50 MSPS with a 30 MHz input, 85 dBc SFDR with a 30 MHz input, ultra-low power at approximately 71 mW per channel at 50 MSPS, an internal 1.8 V LDO for analog supply regulation, an LVDS interface for low-EMI digital output, and per-channel digital gain and offset correction. The device operates from a 1.7 V to 1.9 V AVDD and 1.7 V to 1.9 V DRVDD supply, with a -40C to +85C industrial temperature range. Design considerations include providing adequate 1.8 V supply decoupling on each analog supply pin and routing LVDS output pairs with 100 ohm differential impedance to minimize reflections on the digital data bus. The ADC3242's internal LDO relaxes external regulator noise requirements, but a clean low-ripple source is still recommended for optimal spurious performance.
ADC32J44IRGZ25 - Dual 14-Bit 125MSPS ADC w/ JESD204B | TI
The Texas Instruments ADC32J44IRGZ25 is a dual-channel, 14-bit, 125-MSPS analog-to-digital converter (ADC) with a JESD204B serial interface, housed in a 48-pin VQFN (7x7 mm) package. The device family spans 50 to 160 MSPS, with the "25" speed grade fixing the sample rate at 125 MSPS and the IRGZ industrial temperature option covering -40C to +85C operation. An analog-to-digital converter (ADC) is a data-converter integrated circuit that samples continuous-time analog input signals and produces discrete-time binary codes at its output. ADCs sit inside the broader signal-chain hierarchy: sensor/IF -> analog front end (filter, amp) -> ADC -> digital processor (FPGA, ASIC, DSP). High-speed pipeline ADCs such as the ADC32J44 are widely used in communications, test and measurement, and defense electronics where both sampling rate and dynamic range are critical. The ADC32J44IRGZ25 combines high linearity with ultra-low power: SNR of 72.2 dBFS and SFDR of 87 dBc at 70 MHz input, with channel-to-channel isolation of 105 dB. It integrates a flexible input clock buffer (divide-by-1, -2, -4), an internal dither engine, and a single 1.8 V supply. The JESD204B interface supports up to 3.125 Gbps lane rates, deterministic latency, and synchronization across multiple devices via SYSREF. Architecturally, the part uses a multi-stage pipelined core with digital error correction and on-chip dither to improve small-signal linearity. Each channel has its own track-and-hold and reference buffer; the digital backend packs the two channel streams into 8B/10B-encoded lanes and serializes them out through the JESD204B link, offloading the FPGA from wide LVDS buses. Typical applications include multi-carrier GSM/LTE base-station receivers, software-defined radio (SDR) platforms, radar and electronic-warfare signal capture, and high-speed digitizers for oscilloscopes and spectrum analyzers. In any of these uses the ADC32J44IRGZ25 is paired with a TI clock jitter cleaner and an FPGA/ASIC JESD204B receiver. When designing in this part, plan the PCB layout carefully: keep the analog input traces length-matched and 50-ohm controlled-impedance, place the AVDD/AVSS decoupling capacitors within 2 mm of the supply pins, and isolate the analog and digital ground returns to avoid coupling switching noise into the input stage. A TI LM95233 or equivalent thermal sensor is recommended for monitoring junction temperature in dense systems. This page combines distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet to help engineers select, source, and lay out the ADC32J44IRGZ25 with confidence.
ADC3421IRTQ25 - 12-Bit Quad 25MSPS ADC | Texas Instruments
The Texas Instruments ADC3421IRTQ25 is a quad-channel, 12-bit, 25-MSPS analog-to-digital converter (ADC) in a 56-pin VQFN (RTQ) 8 mm x 8 mm package with exposed thermal pad. The device belongs to TI's ADC342x family of high-linearity, ultra-low power ADCs designed for demanding high-input-frequency signals with large dynamic range requirements. Key headline parameters include 70.2 dBFS SNR, 87 dBc SFDR at 70 MHz input, 98 mW per channel at 125 MSPS, and 105 dB channel isolation. The ADC supports flexible input clock buffer with divide-by-1, -2, -4 options and integrates internal dither plus optional input clock cleaning via a PLL. An analog-to-digital converter (ADC) is a data-acquisition integrated circuit that samples continuous analog signals and converts them to discrete digital codes for downstream processing. ADCs sit at the front-end of the signal chain (sensor -> amplifier/filter -> ADC -> DSP/FPGA/ASIC). The ADC3421 is a pipelined successive-approximation hybrid architecture, well suited for high input frequencies (IF sampling up to 125 MHz) where SAR ADCs become impractical. Pipelined ADCs deliver high sample rates and wide analog bandwidth at the expense of fixed pipeline latency - typically acceptable in communications, imaging, and instrumentation but not in closed-loop control loops. The serial LVDS (SLVDS) digital interface operates from a single 1.8 V supply, reduces pin count versus parallel CMOS interfaces, and simplifies PCB routing at 25-125 MSPS line rates. The internal dither block improves small-signal SFDR by up to 5 dB, while the input clock divider and PLL assist the user in generating the ADC's internal clock from a wide range of external references. Channel isolation of 105 dB minimizes crosstalk between simultaneously sampled channels, which is critical for MIMO receivers and multi-channel test instrumentation. Typical applications include multi-channel communications receivers (LTE, WiMAX, software-defined radio), ultrasound imaging front-ends, portable instrumentation, and digital oscilloscopes. The 25-MSPS sample rate of this -25 speed grade targets narrow-band and lower-power designs; the -125 speed grade (e.g., ADC3423IRTQ25) serves wider-bandwidth applications within the same pin-out. The wide input frequency bandwidth and high SFDR support direct IF sampling architectures that eliminate analog mixer stages. When designing with this device, maintain a low-noise, well-decoupled AVDD/DRVDD layout - separate analog and digital ground planes joined at a single point, with 0.1 uF plus 10 uF decoupling capacitors placed close to each supply pin. Use controlled-impedance differential routing for the LVDS outputs and minimize trace lengths to the FPGA receiver. Provide a stable, low-jitter clock source; jitter directly degrades SNR according to SNR = 20*log10(1 / (2*pi*fIN*tjitter)).

The high-speed ADC category includes pipeline, SAR, and sigma-delta architectures; the ADC342x family uses a pipelined architecture optimized for sampling rates above 25 MSPS. Key features include four simultaneously-sampled input channels, a selectable serial-LVDS (SLVDS) digital interface that reduces board-routing complexity, integrated clock-duty-cycle correction, and a wide input common-mode range supporting both AC- and DC-coupled inputs. The 12-bit resolution combined with high linearity (SFDR > 80 dB typical) makes the device well-suited to multi-channel communication, test, and imaging systems. The architecture uses TI's proprietary low-power pipeline core with on-chip reference and input termination, eliminating many external components. Internal registers control channel gain, offset calibration, and sleep modes. Power consumption scales with sampling rate, allowing trade-offs between bandwidth and thermal budget. Typical applications include multi-channel communications receivers, software-defined radio (SDR) baseband digitizers, multi-channel medical imaging front ends, industrial data acquisition cards, and portable test-and-measurement equipment where four synchronized channels and high SFDR are required. When designing with the ADC3423IRTQ25, carefully plan the LVDS trace layout (100-ohm differential impedance, length matching within 50 mils) and supply decoupling (0.1 uF + 10 uF at each AVDD pin). Heat dissipation is modest at 25 MSPS but rises with sampling rate; derate using the datasheet power-vs-Fs curves.

The ADC3441 belongs to the high-speed pipeline ADC category, which sits inside the data converter family of mixed-signal ICs used in communications, test and measurement, and imaging systems. Pipeline ADCs use a multi-stage switched-capacitor architecture to achieve a balance of sample rate, resolution, and low latency, and are commonly deployed where multi-MHz analog bandwidth must be digitized. Key features of the ADC3441 include a single 1.8 V supply, four differential or single-ended analog inputs, an input clock divider (/1, /2, /4), a SYSREF input for multi-device synchronization, and 105 dB channel-to-channel isolation. Pin-to-pin compatibility with the 12-bit ADC3423 enables resolution upgrades without PCB redesign. The 56-pin VQFN package offers a compact footprint for dense multi-channel designs. The device uses an internal precision reference and a programmable gain stage on each channel. The flexible input clock buffer simplifies clock-tree synthesis in large channel-count systems, while the SLVDS interface reduces FPGA I/O pin consumption compared to parallel CMOS ADCs. Designers should follow TI's recommended power-on and calibration sequencing for optimal DC accuracy. Typical applications include communications receiver IF digitizers, multi-channel data acquisition systems, oscilloscope front-ends, medical imaging, and radar baseband sampling. The combination of low power and high dynamic range makes the ADC3441 particularly suited to portable and thermally constrained systems. When designing with this ADC, follow TI's recommended decoupling scheme (typically a 1 uF plus 0.1 uF per supply pin pair) and place the SLVDS trace lengths matched within the FPGA to preserve timing budget. The ADC3441's thermal pad must be soldered to a sufficient ground copper pour to keep junction temperature below the 125C maximum. This page synthesizes TI distributor pricing, same-family alternatives, and application guidance not found in a single source, helping engineers select, source, and design with the ADC3441IRTQ25 more efficiently.
ADC34J23IRGZ25 - Quad 12-bit 80MSPS ADC | Texas Instruments
The Texas Instruments ADC34J23IRGZ25 is a quad-channel, 12-bit, 80-MSPS analog-to-digital converter (ADC) housed in a 48-pin VQFN (RGZ) package measuring 7x7 mm. The device integrates four pipelined ADC cores that sample simultaneously, supporting per-channel input bandwidths suitable for multi-antenna wireless base stations, instrumentation digitizers, and quad-channel medical or industrial acquisition systems. It operates from a low-voltage 1.8 V supply for the analog front-end and supports a separate digital I/O supply for easy host-interface level shifting. An ADC (analog-to-digital converter) is a data-converter IC that translates real-world analog signals into discrete digital codes for processing by FPGAs, ASICs, microcontrollers, or DSPs. Pipeline ADCs in particular are favored for sample rates between a few MSPS and several hundred MSPS because they combine high throughput with low per-channel power. The ADC34J23 sits at the interface layer of any signal chain — between analog signal-conditioning (amplifiers, filters, drivers) and the digital domain (FPGA, processor, JESD204B/C link, or LVDS bus). Industry synonyms include "high-speed ADC," "IF-sampling ADC," and "digitizer IC." Key specifications include 12-bit resolution, 80 MSPS maximum sampling rate (configurable 50 to 160 MSPS across the family), four simultaneous sampled inputs, pipelined architecture for low latency, low-voltage differential signal (LVDS) digital interface to the host FPGA, and a 1.8 V analog supply. Each channel achieves excellent linearity across the industrial temperature range, and the integrated input buffer simplifies front-end design. The architecture combines four pipelined core ADCs with on-chip reference and timing-generation circuits, enabling software-configurable sample rates, channel-power scaling, and test-pattern injection. The device supports both internal and external reference operation, allowing designers to optimize drift performance versus BOM count. Typical applications include multi-antenna wireless base-station receivers, radar and phased-array digitizers, cable-infrastructure head-ends, ultrasound and other medical imaging front-ends, and automated test equipment (ATE). The four matched channels also suit multi-axis vibration or current-sensing systems in industrial monitoring. When designing with the ADC34J23, match the LVDS trace lengths on the digital bus to within short skew budgets and provide a clean 1.8 V analog LDO, such as the TPS7A47 family, on each AVDD pin to preserve SNR. Use the device's power-down modes between acquisitions in low-duty-cycle applications to reduce dissipation.

ADC34J24IRGZ25 - Quad 12-Bit 125 MSPS JESD204B ADC | Texas Instruments
The Texas Instruments ADC34J24IRGZ25 is a quad-channel, 12-bit, 125-MSPS analog-to-digital converter (ADC) with a JESD204B serial interface, housed in a 48-pin VQFN (RGZ) package measuring 7 mm x 7 mm. It delivers 69.6 dBFS SNR and 86 dBc SFDR at an input frequency of 70 MHz, supports four differential analog input channels, and operates from a single 1.8 V supply with channel isolation of 105 dB and ultra-low per-channel power consumption of 203 mW at 160 MSPS. What is a JESD204B ADC? JESD204B is a high-speed serial interface standard (JEDEC JESD204B, revision 2011) that converts parallel LVDS data into a small number of differential serial lanes. It eliminates the wide parallel bus of older ADCs, reducing PCB area, lane count, and skew problems in multi-channel systems. An ADC in the ADC34Jxx family is a pipelined successive-approximation hybrid converter (pipelined core) with internal dither, designed for direct sampling of IF/RF signals in 4G/5G base stations, radar, and industrial imaging where multi-channel synchronization is required. The device integrates a flexible input clock buffer with divide-by-1, -2, and -4 options, allowing one of three JESD204B lane rates to be selected from a common reference oscillator. Internal dither improves SFDR for small-swing inputs near full scale. According to the TI product page for ADC34J24, this part is pin-to-pin compatible with the 14-bit ADC34J25 family, enabling a single PCB to support either resolution tier. Typical applications include wireless base-station receivers (4G LTE, 5G NR, multi-carrier GSM), phased-array radar digitizers, medical ultrasound beamformers, industrial digitizers, and multi-channel test & measurement. The industrial temperature grade (-40C to +85C) and 48-VQFN exposed-pad package support compact, fan-less embedded designs. When designing with this ADC, use a low-noise LDO (e.g., a TPS7A47xx family part) to derive the AVDD_1V8 rail from a system supply, and keep the analog input traces length-matched to preserve 105 dB channel-to-channel isolation. The exposed thermal pad (EP) must be soldered to a continuous ground plane on the top layer for proper heat dissipation, since the device dissipates roughly 800 mW total at 125 MSPS across four channels.
ADC34J25IRGZ25 - Quad 12-Bit 160MSPS ADC w/ JESD204B | Texas Instruments
The Texas Instruments ADC34J25IRGZ25 is a quad-channel, 12-bit, 50-MSPS to 160-MSPS pipelined analog-to-digital converter housed in a 48-pin VQFN (7x7 mm, RGZ) package. It integrates four ADC channels sharing a single 1.8 V supply and achieves 69.6 dBFS SNR with 86 dBc SFDR at fIN = 70 MHz, making it well suited for multi-antenna wireless base stations and broadband communications. The product type is a high-speed pipelined ADC. A pipelined analog-to-digital converter is a semiconductor device that converts continuous analog waveforms into discrete digital codes by sampling the input against a held reference through multiple low-resolution flash stages; it belongs to the broader category of data converters (which also includes successive-approximation, delta-sigma, and flash ADCs) within the integrated circuit family. Pipelined ADCs sit at the apex of speed-vs-resolution trade-offs and dominate the 50-500 MSPS range used in communications infrastructure, radar, and instrumentation. Key features include a flexible input clock buffer with divide-by-1, -2, -4 options, an internal dither engine for improved small-signal linearity, a 105 dB channel-to-channel isolation, and ultra-low power consumption of 203 mW per channel at 160 MSPS. A JESD204B-compliant serial output interface (subclass 1) allows up to four ADCs to share a single high-speed digital lane back to an FPGA or ASIC. Architecturally, the device uses four time-interleaved pipelined cores with on-chip input buffers, a shared bandgap reference (external reference supported), and an integrated digital processing block. Pin compatibility with the 14-bit ADC34J22 family allows drop-in migration when higher dynamic range is required without PCB rework. Typical applications include wireless base-station receivers (multi-antenna MIMO), radar digitizers, medical imaging front-ends, and broadband test equipment. The device is well suited when synchronization across multiple channels and compact board area are required. When designing with this ADC, plan input network termination to 50 ohms and provide low-jitter clocking; the JESD204B link requires deterministic latency, so use subclass 1 SYSREF for multi-device alignment. PCB stack-up should keep the analog and digital grounds separated until joined under the exposed pad.

ADC34J42IRGZ25 - Quad 14-Bit 50MSPS ADC, JESD204B | Texas Instruments
The Texas Instruments ADC34J42IRGZ25 is a quad-channel, 14-bit, 50-MSPS to 160-MSPS analog-to-digital converter (ADC) housed in a 48-pin VQFN (RGZ 7x7 mm) package. The part is from the ADC34J4x family and ships in the IRGZ25 tape-and-reel option, qualified for the industrial -40C to +85C temperature range. An analog-to-digital converter (ADC) is a data-acquisition integrated circuit that samples continuous analog input signals and converts them into discrete digital codes at a rate defined by an external clock. In the signal-chain taxonomy, ADCs sit between the analog front end (amplifiers, filters, anti-alias networks) and the digital back end (FPGA, ASIC, processor). Pipelined ADCs such as the ADC34J4x family use a multi-stage architecture that delivers high sampling rates (>50 MSPS) with low power per channel, which is why they dominate communications, radar, and multi-channel instrumentation. Key features of the ADC34J42IRGZ25 include: quad simultaneous sampling channels at up to 160 MSPS, a flexible input clock buffer with divide-by-1, -2, and -4 modes, ultra-low power consumption of 203 mW per channel at 160 MSPS, a single 1.8 V supply, internal dither for improved small-signal linearity, and a JESD204B serial interface that supports Subclass 0, 1, and 2 operation. The device achieves SNR of 72 dBFS and SFDR of 86 dBc at fIN = 70 MHz, with 105 dB channel-to-channel isolation across the four channels. The architecture is built on a TI proprietary CMOS process with internal dither to randomize the residue amplifier's non-linearity, improving SFDR for input frequencies well above Nyquist. The flexible clock input buffer simplifies clock-tree design on multi-ADC boards because the same reference oscillator can be divided down for different boards. The JESD204B interface removes wide LVDS parallel buses, reducing board area, FPGA pin count, and channel-to-channel skew. Typical applications include multi-channel cellular base-station receivers, software-defined radio, cable-headend digitizers, medical imaging front ends, radar and LIDAR signal chains, and high-channel-count test and measurement digitizers. The 160 MSPS ceiling and JESD204B output make it well suited for phase-coherent multi-channel systems. When designing with the ADC34J42, follow TI's recommended JESD204B link-parameter programming in the datasheet and provide a low-jitter clock to the CLK input to preserve SNR. The internal dither must remain enabled for the published SFDR figures. The 48-VQFN requires a thermal pad soldered to a sufficiently large ground copper pour.

The Texas Instruments ADC34J43IRGZ25 is a quad-channel, 14-bit, 80-MSPS pipelined analog-to-digital converter with JESD204B serial interface, housed in a 48-pin VQFN (RGZ) 7x7 mm package. It features four differential analog inputs, an integrated clock divider, and supports input frequencies up to the Nyquist rate for wideband signal capture. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts continuous-time analog voltages into discrete digital codes at a sampling clock rate, enabling downstream DSP, FPGA, or ASIC processing. ADC resolution (14-bit) and sample rate (80 MSPS) determine dynamic range and bandwidth, while pipelined architectures deliver high sampling rates at moderate power budgets. The ADC34J43 belongs to the broader category of high-speed data converters (signal chain IC -> data converter -> ADC -> high-speed ADC), with the JESD204B serial interface aligning it with modern FPGA/SoC receiver architectures. Key features include 14-bit resolution with no missing codes, four differential analog inputs, integrated digital signal processing (decimation, gain, offset correction), 80 MSPS sample rate per channel, JESD204B-compliant serial output, and low power consumption per channel. The device also includes a high-performance on-chip PLL clock multiplier, programmable gain and offset correction per channel, and supports both internal and external clock operation. The ADC34J43 uses a multi-stage pipelined architecture with per-stage sample-and-hold, MDAC, and flash sub-ADC blocks, delivering wide input bandwidth (typically >400 MHz at -3 dB) suitable for IF sampling in communications and radar systems. Its JESD204B serial interface supports up to 3.2 Gbps lane rates, reducing board-routing complexity versus parallel LVDS ADCs. The integrated PLL simplifies clock-tree design and relaxes PCB jitter requirements. Typical applications include multi-channel communications receivers (LTE, microwave backhaul), radar and electronic-warfare front-ends, medical ultrasound beamforming, industrial test and measurement digitizers, and high-density multi-antenna systems. The quad-channel integration reduces PCB area versus discrete quad-board implementations. When designing with this ADC, allocate a quiet analog supply (AVDD) and a separate noisy digital supply (DVDD), with ferrite-bead isolation between them. Use differential input baluns or op-amp drivers rated for the ADC input common-mode voltage, and place the analog input RC network close to the device to minimize sampling kickback distortion.

ADC34J44IRGZ25 - Quad 14-bit 125 MSPS ADC w/ JESD204B | Texas Instruments
The Texas Instruments ADC34J44IRGZ25 is a quad-channel, 14-bit, 125 MSPS pipelined analog-to-digital converter (ADC) with a JESD204B serial interface, housed in a 48-pin VQFN (7x7 mm, RGZ) package. According to the ADC34J4x datasheet (Rev. B), the device delivers 72 dBFS SNR and 86 dBc SFDR at f_IN = 70 MHz, with 203 mW per channel power consumption at 160 MSPS and 105 dB channel-to-channel isolation. The ADC34J44 family supports 50, 80, 125, and 160 MSPS speed grades in a single design, with pin-compatible migration between speed grades. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous analog voltage or current signals into discrete digital codes for downstream processing by FPGAs, ASICs, or microprocessors. The ADC34J44 belongs to the pipelined ADC subclass — the dominant architecture for sample rates between 1 MSPS and 1 GSPS — which uses a multi-stage cascaded architecture with residue amplification between stages to achieve high throughput. Within the broader IC taxonomy, this part sits as: ADC -> data converter -> mixed-signal IC -> semiconductor. The 'J' suffix in the part number denotes TI's high-speed JESD204B-interface family, a standardized serial link that simplifies multi-lane synchronization between data converters and logic devices. Key features include an ultra-low power consumption of 203 mW per channel at 160 MSPS, a flexible input clock buffer supporting divide-by-1, -2, and -4, an internal dither engine for improved SFDR on small-signal inputs, and a JESD204B interface supporting Subclass 0, 1, and 2 deterministic latency with up to one lane per ADC. The 48-VQFN package with exposed pad provides a low thermal resistance path (θJA ~22 C/W) suitable for the device's modest power dissipation at 125 MSPS, eliminating the need for an external heatsink in most designs. The device operates from a single 1.8 V supply and accepts differential analog inputs with a 1.0 Vpp full-scale range, with the input common-mode set internally to simplify board design. Multi-chip synchronization ( MCS ) is supported through the SYSREF and SYNC~ pins, enabling deterministic phase alignment across multiple ADC34J4x devices in phased-array, MIMO, or beam-forming systems. The internal dither circuit improves spurious-free dynamic range (SFDR) by 2-4 dB on small-signal inputs near the noise floor, which is critical for communications receivers where blocker signals may otherwise dominate. Typical applications include multi-channel communications infrastructure (cellular base station receivers, software-defined radio, microwave backhaul), industrial imaging systems (medical ultrasound, non-destructive testing, machine vision), multi-channel data acquisition systems for test and measurement instrumentation, and defense electronics such as phased-array radar and electronic warfare systems. The combination of four synchronized channels on a single die reduces board area, BOM cost, and channel-to-channel mismatch in tightly-coupled systems. When designing with the ADC34J44IRGZ25, route the JESD204B serial lanes as 100-Ω differential stripline/microstrip pairs with length matching within the lane (typically <0.5 mm) and across lanes (<6.25 UI per datasheet). Place decoupling capacitors as close as possible to each supply pin (1.0 µF ceramic plus 0.1 µF at the pin, plus bulk capacitance near the regulator), and provide a solid ground reference beneath the JESD204B traces. The internal dither must be enabled when the input signal can approach the -35 dBFS noise floor; disable only if downstream spectral purity is already adequate and you need to save 1-2 mW per channel. This page synthesizes distributor pricing, pin-compatible same-family drop-in alternatives (ADC34J42IRGZ25, ADC34J25IRGZ25, ADC32J44IRGZ25), and practical JESD204B layout guidance that is not collected in a single location on the manufacturer datasheet — information gain that distributors and simple parametric search tools do not provide.
ADC78H89CIMT - 7-Ch 500kSPS 12-Bit SAR ADC | Texas Instruments
The Texas Instruments ADC78H89CIMT is a low-power, 7-channel, 12-bit successive-approximation-register (SAR) analog-to-digital converter with a 500 KSPS throughput, housed in a 16-pin TSSOP package. Originally a National Semiconductor design now owned by Texas Instruments, the ADC78H89 accepts up to seven single-ended analog inputs on pins AIN1 through AIN7 and delivers straight-binary serial data through an SPI/QSPI/MICROWIRE-compatible interface. A SAR ADC is a type of data converter that performs a binary search across an internal capacitive DAC to resolve each analog sample in N clock cycles, where N is the resolution. The SAR architecture combines deterministic latency with inherent anti-alias filtering and is widely used in multiplexed data-acquisition systems, motor control loops, and instrumentation front-ends. SAR converters sit within the broader hierarchy of analog-to-digital converters (ADC -> data converter -> signal chain IC -> semiconductor) and trade the continuous-time linearity of delta-sigma ADCs for true single-shot sampling and low power dissipation. Key features of the ADC78H89CIMT include ±1 LSB maximum DNL and ±1 LSB maximum INL, an operating temperature range of -40 °C to +85 °C, and very low power consumption: typically 1.5 mW at 3 V supply and 8.3 mW at 5 V supply. The 16-pin TSSOP footprint offers a small board area suitable for portable or space-constrained designs, while the internal track-and-hold and serial interface minimize external component count. The device operates from a 2.7 V to 5.25 V analog supply, supporting both 3 V and 5 V system rails. The SAR core, internal reference option, and seven-channel input multiplexer make the part a single-chip solution for sensor-array digitizing where deterministic latency and low power are more important than raw conversion speed. Designers can run the part from an external clock or the internal oscillator depending on system timing constraints. Typical applications include automotive navigation and infotainment subsystems, portable battery-powered instruments, medical instrumentation such as patient-monitoring front-ends, mobile-communication baseband signal-conditioning, and general-purpose industrial instrumentation and control systems. Its low power also suits remote, solar-powered sensor nodes. A key design consideration is that the /CS, SCLK, DOUT, and DIN pins form the four-wire serial interface, and the AIN0-AIN6 pins share a common ground reference. Decouple AVDD with a 10 µF and 0.1 µF pair placed within 5 mm of the supply pin, and keep digital return currents isolated from the analog ground return to preserve the device's specified DNL/INL. This page consolidates distributor pricing, drop-in TSSOP-16 alternatives, and practical design guidance that are not available in the manufacturer's datasheet alone.

The converter accepts up to seven single-ended input signals on pins AIN1 through AIN7 and produces straight-binary serial output data over an SPI-compatible interface. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that converts continuous analog signals into discrete digital codes; SAR ADCs use a binary-search capacitor network to resolve each conversion in N clock cycles, making them well-suited for multiplexed multi-channel systems where low latency and deterministic behavior are required. The ADC78H89 sits in the broader hierarchy of SAR ADC -> data converter -> data acquisition IC -> signal chain IC -> semiconductor. Multi-channel SAR ADCs like this one are commonly used to digitize several sensor or control signals through a single serial port, reducing MCU pin count and BOM cost. Key specifications include 12-bit resolution, a 500 kSPS conversion rate, seven analog input channels, an internal track-and-hold circuit, single-supply operation from 2.7 V to 5.25 V, and a straight-binary serial data output. The architecture supports pseudo-differential or single-ended inputs and includes a hardware shutdown pin to reduce current consumption between conversions, which is important for battery-powered and thermally-constrained designs. The SAR core is paired with an on-chip input multiplexer, sample-and-hold amplifier, and an SPI/QSPI/MICROWIRE-compatible serial I/O block. The internal reference and clock options reduce external component count, while the TSSOP-16 footprint allows the part to be placed in compact multiplexed sensor front ends. Typical SNR and INL behavior of this family is suitable for general-purpose 12-bit precision instrumentation rather than audio or 16+ bit precision. Typical applications include multi-sensor data acquisition in industrial control, battery monitoring in portable instrumentation, HVAC and appliance sensor aggregation, microcontroller-based measurement nodes, and general-purpose multi-channel instrumentation. Designers select this ADC when 12-bit accuracy, seven channels, and SPI connectivity are sufficient and lowest-cost general-purpose conversion is desired. When designing with the ADC78H89CIMTX, ensure that the analog supply is well decoupled (typically a 10 µF bulk plus 0.1 µF ceramic close to AVDD), that the SCLK frequency respects the 500 kSPS timing budget across all seven channels, and that the CS/SHUTDOWN logic is sequenced correctly to enter low-power shutdown between conversions.

The part accepts up to eight single-ended input signals at AIN1 through AIN8 and outputs straight binary serial data compatible with standard SPI/QSPI/MICROWIRE interfaces, supporting -40C to +85C operation. An SAR ADC is a precision data converter that uses a binary search algorithm and an internal track-and-hold to digitize analog signals at the moment of sampling; SAR ADCs are prized for low latency, deterministic throughput, and excellent dc accuracy, sitting hierarchically under analog-to-digital converter -> data converter -> mixed-signal IC -> semiconductor. The ADC78H90 family is intended for multi-channel, low-power monitoring tasks where deterministic sampling and a small footprint matter more than the highest possible sample rate. Key specifications of the ADC78H90 include 12 bits of resolution, 500 kSPS maximum throughput, eight analog input channels selected by internal addressing, and a CMOS successive-approximation architecture with an internal track-and-hold circuit. The serial output data is straight binary, which simplifies host firmware and avoids the overhead of two's-complement decoding in microcontrollers and DSPs. Architecturally, the device combines a low-power CMOS SAR core, an 8-channel analog multiplexer, an internal reference/sample-and-hold, and a simple synchronous serial interface (SCLK, DOUT, CS). The deterministic per-conversion latency makes the part well-suited to multiplexed multi-channel scanning without the phase-skew issues that plague some delta-sigma ADCs in control loops. Typical applications include sensor and transducer monitoring in industrial control, process automation analog front ends, portable battery-powered instrumentation, multi-channel data-acquisition modules, and consumer audio or appliance front panels where up to eight analog signals must be read from a small PCB. Design tip: this part is supplied under the IMT tape-and-reel designation (TSSOP-16 PW); the rail variant carries /NOPB marking per Texas Instruments product naming. Ensure the SPI host supports the chosen SCLK frequency at 500 kSPS and that digital and analog grounds are tied at a single star point to preserve 12-bit accuracy.

The ADC912BW/883 is also suitable for test and measurement equipment requiring high precision and stability. When designing with this ADC, ensure proper decoupling of the power supply and reference inputs to minimize noise. The conversion start (SC) pin initiates conversions, and the end-of-conversion (EOC) output can be used for interrupt-driven data transfer. For best performance, use a low-impedance analog source and a stable reference voltage.
ADCS7476AIMF/NOPB - 1MSPS 12-Bit SAR ADC, SOT-23-6 | Texas Instruments
The Texas Instruments ADCS7476AIMF/NOPB is a 12-bit, 1 MSPS, low-power, monolithic CMOS successive-approximation-register (SAR) analog-to-digital converter housed in a 6-pin SOT-23 package with a 2.7V to 5.25V analog supply range. Per the manufacturer datasheet, the device accepts a single-ended analog input and provides the conversion result through an SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface, making it one of the smallest full-spec 1 MSPS 12-bit ADCs available in a SOT-23 footprint. 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 precision DAC to determine each code bit in N clock cycles. SAR ADCs are valued for their deterministic latency, lack of pipeline delay, and excellent DC accuracy, sitting hierarchically below pipelined ADCs (used) and delta-sigma ADCs (used) and above simple flash ADCs in the data-converter taxonomy. Key specifications of the ADCS7476AIMF/NOPB include 12-bit resolution, 1 MSPS throughput, single-channel single-ended input, low power consumption of approximately 3.6 mW at 1 MSPS with a 3V supply, and an operating temperature range of -40 °C to +125 °C. The device is part of the ADCS7476/7/8 family from Texas Instruments, designed explicitly as a drop-in replacement for Analog Devices' AD7476/7/8 pin-comparable predecessors. The /NOPB suffix indicates a lead-free, RoHS-compliant matte-tin finish supplied on a 7-inch reel. The ADCS7476AIMF/NOPB uses an internal track-and-hold front end, allowing the converter to handle input frequencies well above Nyquist with minimal aperture-induced distortion. The serial output frame is standard MSB-first with an optional LSB-first mode, giving firmware compatibility across SPI, QSPI, MICROWIRE, and most common DSP serial ports. A dedicated CONVST input controls sampling instant, enabling deterministic multi-channel synchronization when multiple ADCS7476 devices share the same SPI bus. Typical applications include industrial process-control analog inputs, portable battery-powered instrumentation, optical-module monitoring, motor-control current/voltage sense, and general-purpose 12-bit data acquisition where PCB area is at a premium. Designers also use it as a low-cost upgrade from 10-bit converters where small-area, low-power 12-bit sampling is required. When designing with this part, place the 0.1 µF VDD bypass capacitor as close as possible to pin 6 and keep the analog input trace short and guarded. Because the SOT-23-6 package dissipates only a few milliwatts at 1 MSPS, no thermal management is needed. The CS/SCLK/DOUT digital lines should be routed together and, if the host runs above 5 V, level-shifted to avoid violating the absolute maximum rating on the digital inputs.

ADCS7477AIMF - 10-Bit 1MSPS SAR ADC, SOT-23-6 | Texas Instruments
The Texas Instruments ADCS7477AIMF is a 10-bit, 1 MSPS successive-approximation-register (SAR) analog-to-digital converter housed in a 6-pin SOT-23-6 package. It operates from a 2.35 V to 5.25 V analog and digital supply and consumes only a few milliwatts at full sampling rate, targeting size-constrained portable and industrial designs. The converter uses a low-power CMOS architecture with internal track-and-hold and exposes a serial interface compatible with SPI, QSPI, MICROWIRE, and most DSP serial ports. A SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary-search algorithm against an internal DAC to determine each code, requiring only N conversion cycles for an N-bit sample. SAR ADCs sit between slower integrating converters and high-speed pipelined flash ADCs in the data-converter hierarchy: data converter -> ADC -> successive approximation ADC -> medium-speed monolithic ADC -> power management / signal-chain IC. SAR architectures are prized for deterministic latency, low power, and excellent DC accuracy, which is why they dominate industrial control, instrumentation, and battery-powered sensor applications. Key features of the ADCS7477AIMF include 1 MSPS throughput, 10-bit resolution with no missing codes, an internal 2.5 V reference option (ADCS7478 / ADCS7476 variants adjust resolution), a true-differential analog input stage, and a hardware-friendly shutdown pin that drops supply current to microamp levels for power-cycled applications. The 6-pin SOT-23 footprint makes the device the smallest member of TI/NSC's ADCS747x monolithic ADC family. Typical applications include portable instrumentation, optical module monitoring, high-speed data acquisition front-ends, motor-control feedback sampling, and precision sensor signal chains where compact PCB area and deterministic latency are required. The combination of low power consumption, small footprint, and industry-standard SPI-compatible interface makes this part attractive for designers migrating from legacy parallel ADCs that consumed far more board area. A primary design trade-off is the choice of internal-versus-external voltage reference: the internal reference minimizes external BOM but constrains absolute accuracy, whereas an external reference improves gain error and temperature drift at the cost of an extra component and pin. Adding a 0.1 µF ceramic decoupling capacitor within 5 mm of the AVDD pin and a small RC anti-alias filter at AIN is recommended. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond what is found on DigiKey, Mouser, or TI's product page, giving engineers a single canonical reference for the ADCS7477AIMF.
ADCS7478AIMF - 1MSPS 8-Bit ADC SAR SPI SOT-23-6 | Texas Instruments
The Texas Instruments ADCS7478AIMF is a low-power, monolithic CMOS 8-bit analog-to-digital converter that operates at 1 MSPS in a 6-pin SOT-23 package. It uses a successive approximation register (SAR) architecture with an internal track-and-hold, single 2.7V to 5.25V supply operation, and a serial interface compatible with SPI, QSPI, and MICROWIRE standards. The ADCS7478AIMF is part of the ADCS747x drop-in replacement family for the legacy Analog Devices AD7476/77/78 series. An analog-to-digital converter (ADC) is a data conversion device that converts a continuous analog voltage into a discrete digital code. Within the broader data converter hierarchy, an ADC sits inside signal chain ICs -> data converters -> ADCs. SAR ADCs sample the input once per conversion, then perform a binary search through an internal DAC to resolve the bits, offering deterministic latency and excellent DC accuracy with very low power consumption at moderate sample rates. The ADCS7478AIMF targets cost- and size-sensitive embedded designs needing 8 bits of resolution at up to 1 MSPS. Key features include 1 MSPS throughput, an SPI/QSPI/MICROWIRE-compatible serial interface, an on-chip clock, single 2.7V to 5.25V supply with the supply used as the reference, and an analog input range from 0V to VDD. The part draws only a few mW during active conversion and supports power-down modes for battery-powered or duty-cycled applications. The SOT-23-6 footprint measures roughly 2.9mm x 1.6mm, making the converter one of the smallest 1 MSPS SAR ADCs available. The ADCS7478AIMF is built on a CMOS process with an internal track-and-hold front end and a charge redistribution SAR core. It uses VDD as its reference voltage, eliminating the need for an external reference. The serial data output is straight binary, and the conversion rate is fixed at the internal oscillator. According to TI's datasheet, the device can also be used with an external reference by injecting a reference voltage through the VDD pin when configured appropriately. Typical applications include portable data loggers, isolated voltage and current sensing in industrial controls, optical module monitoring, system monitoring and housekeeping on microcontroller cards, and battery management in portable medical devices. The combination of small package, low power, and standard SPI interface lets the ADCS7478AIMF sit directly behind a sensor or shunt, sending readings back to a microcontroller with minimal firmware overhead. When designing with the ADCS7478AIMF, ensure the SPI clock is provided only during conversion and acquisition. Decouple VDD with a 100nF ceramic capacitor placed as close to pin 6 as possible, and keep the analog input trace short and guarded to ground. Verify that the microcontroller SPI mode matches the ADC's clock polarity and phase (CPOL=0, CPHA=0 by default).
