ADS6124IRHB25 - 12-Bit 105MSPS Low-Power ADC | Texas Instruments

The Texas Instruments ADS6124IRHB25 is a 12-bit, 105-MSPS pipelined analog-to-digital converter with selectable DDR LVDS or parallel CMOS outputs, housed in a 32-pin VQFN (5x5 mm) package with an exposed thermal pad. It delivers low power consumption, internal references, and supports sampling rates of 65/80/105/125 MSPS within the ADS612x family. The converter features a single analog input channel, internal sample-and-hold, and an internal voltage reference, eliminating the need for external reference components. An ADC (analog-to-digital converter) is a semiconductor device that converts continuous analog signals into discrete digital codes, serving as the bridge between real-world analog phenomena (sensor outputs, RF signals, audio) and digital signal processing. Within the broader taxonomy, the ADS6124 is a successive-approximation/pipelined ADC, the dominant architecture for medium-to-high-speed data acquisition. Pipelined ADCs use a multi-stage architecture with sub-ADCs and DACs to achieve high sample rates at moderate resolution, balancing speed and accuracy through a tradeoff between latency and resolution. Key features of the ADS6124IRHB25 include 12-bit resolution, 105 MSPS maximum sampling rate, LVDS/CMOS selectable digital interface, low power architecture, internal reference, and an industrial temperature range of -40C to +85C. The part comes in a compact 32-VQFN exposed-pad package that provides improved thermal performance for the sustained operation required at full sample rate. Typical applications include communications base-station receivers, test and measurement equipment, medical imaging front-ends, multi-channel data acquisition systems, and radar signal processing. The wide input bandwidth and LVDS output option make it well-suited for IF sampling and high-density channel card designs. When designing with this ADC, pay close attention to the analog input network: a transformer or differential driver is normally used to drive the analog inputs to maximize SFDR. Decoupling the AVDD and DRVDD rails with low-ESR ceramic capacitors placed close to the package improves noise immunity, and the exposed pad must be soldered to a sufficiently large PCB ground pour for thermal dissipation.

ADS6129IRGZ25

ADS6129IRGZ25 - 12-Bit 250MSPS Low-Power ADC | Texas Instruments

The Texas Instruments ADS6129IRGZ25 is a 12-bit, 250 MSPS, single-channel pipelined analog-to-digital converter (ADC) housed in a 48-pin VQFN (7x7 mm) package with an exposed thermal pad. It belongs to the ADS612X/ADS614X family of low-power, high-dynamic-performance ADCs from TI and supports both LVDS (DDR) and parallel CMOS digital outputs. The device operates from 1.8 V to 3.3 V analog/digital supplies, draws approximately 430 mW at 250 MSPS in CMOS mode, and is specified over the -40 °C to +85 °C industrial temperature range. The wide input bandwidth and high spurious-free dynamic range make it suitable for IF/RF sampling in communications infrastructure. What is a pipelined ADC? A pipelined analog-to-digital converter is a high-speed ADC architecture that processes the analog input through a cascade of low-resolution sub-ADC stages, each performing a coarse quantization followed by a residue amplification to the next stage. This architecture trades latency for throughput and dominates the >100 MSPS speed class because it scales efficiently with process technology. Pipelined ADCs sit hierarchically under successive-approximation (SAR) and flash ADCs in the high-speed converter tree, with sub-categories such as low-power pipelined, high-SFDR pipelined, and pipelined-with-LVDS-output families. Key features include 70 dBFS SNR at 100 MHz input, 85 dBc SFDR, an integrated high-bandwidth track-and-hold, internal reference, and programmable digital output modes. The LVDS DDR interface allows a single data-rate clock while emitting data on both rising and falling edges, simplifying FPGA capture at 250 MSPS. The CMOS mode permits direct 12-bit parallel bus connection to ASICs and DSPs. Internal register programming supports gain, offset, and test-pattern modes for board-level diagnostics. The ADS6129 uses a switched-capacitor front-end optimized for differential transformer-coupled inputs of 2 Vpp full-scale, with common-mode voltage set by the internal reference. The architecture achieves 1.5 GHz usable analog input bandwidth, enabling undersampling of IF signals up to 400 MHz. Power scales roughly linearly with fS, dropping to ~330 mW at 210 MSPS for power-constrained designs. Typical applications include multi-carrier wireless infrastructure (LTE, MC-GSM), software-defined radio (SDR), power amplifier linearization feedback paths, 802.16d/e WiMAX base stations, radar systems, medical imaging digitizers, and high-definition video capture. The combination of low power and high SFDR makes it especially attractive for dense multi-channel receiver cards. When designing with this part, ensure the analog input is AC-coupled through a 1:1 or 1:2 transformer and that the LVDS/CMOS termination matches the receiver impedance. Decouple AVDD and DRVDD separately and keep the exposed thermal pad soldered to a continuous ground plane for the rated thermal performance.

The part belongs to TI's ADS614X family that includes the ADS6142, ADS6143, ADS6144, and ADS6145 devices, all sharing the same pinout and offering sample-rate options up to 125 MSPS. The -25 suffix denotes the industrial temperature range of -40C to +85C, and the IRHB25 designation indicates the tape-and-reel, RHB (VQFN-32) package variant. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts a continuous-time, continuous-amplitude analog input voltage into a discrete-time, discrete-amplitude digital code. Pipelined ADCs use a cascade of low-resolution flash stages with inter-stage digital error correction, achieving a practical trade-off between sampling rate (tens to hundreds of MSPS), resolution (10-16 bits), and power consumption. Within the broader signal chain hierarchy, an ADC sits between an analog front-end (amplifiers, filters, mixers) and a digital processor (DSP, FPGA, microcontroller), and is itself part of the larger class of data converters that also includes digital-to-analog converters (DACs). Key features of the ADS6144IRHB25 include 105 MSPS maximum sample rate, 14-bit resolution, and a typical integral nonlinearity (INL) of +/-1.5 LSB at 105 MSPS. The device operates from a single 3.3 V analog supply and a 3.3 V (or selectable 1.8 V) digital supply, consuming approximately 130 mW at 105 MSPS in CMOS mode. Selectable parallel CMOS or LVDS outputs give designers the option to optimize for low-power I/O or high-noise-immunity backplane links, while internal references and an input common-mode buffer simplify the analog front-end design. The ADS6144IRHB25 uses a multi-stage pipelined architecture with proprietary digital error correction, achieving an effective number of bits (ENOB) greater than 11 bits at the Nyquist frequency. An integrated high-bandwidth track-and-hold and on-chip reference deliver low aperture jitter and stable full-scale performance across temperature. The LVDS output mode doubles the maximum output data rate relative to CMOS, enabling efficient data transfer to FPGAs or DSPs without external bus drivers. Typical applications include wireless communication base-station receivers, IF sampling in software-defined radio, portable ultrasound imaging front-ends, high-speed instrumentation, and CCD/CMOS imaging digitizers. The 105 MSPS rate is well-suited to IF-sampling architectures below 50 MHz input. When designing with this device, ensure the analog input is driven by a low-impedance, AC- or DC-coupled amplifier with proper 50-ohm termination if the source is single-ended. Decouple both AVDD and DRVDD pins with low-ESR ceramic capacitors placed within 5 mm of the supply pins.

ADS61B29IRGZ25 - 12-Bit 250MSPS Buffered ADC | Texas Instruments

The Texas Instruments ADS61B29IRGZ25 is a 12-bit, 250-MSPS analog-to-digital converter with an integrated high-impedance analog input buffer, housed in a 48-pin VQFN (RGZ) 7x7 mm package. According to the manufacturer datasheet, the device combines high dynamic performance with low power consumption (790 mW typical at 250 MSPS), making it suitable for high-IF sampling receiver chains where transformer-based front ends would otherwise be required. The integrated buffer eliminates the need for an external ADC driver, simplifying board layout and reducing BOM cost while preserving signal integrity at high input frequencies. An ADC (Analog-to-Digital Converter) is a data-conversion IC that samples continuous-time analog signals and outputs discrete digital codes. The 12-bit resolution class sits in a hierarchy between 8/10-bit general-purpose converters and 14/16-bit precision converters, balancing dynamic range against conversion speed. The ADS61B29 belongs to the pipelined ADC family, which uses multiple low-resolution stages to achieve high sample rates (>100 MSPS) at moderate resolution - ideal for communications, radar, and test-and-measurement front ends where wide capture bandwidth matters more than absolute DC precision. Key features include 250 MSPS maximum sample rate, integrated high-impedance analog input buffer, LVDS parallel data interface, single 3.3V analog supply, internal sample-and-hold ratio of 1:1, and industrial operating temperature range of -40C to +85C. The pipelined architecture delivers consistent dynamic performance across the full Nyquist bandwidth, with low spurious and harmonic distortion suitable for multi-carrier receiver designs. The ADS61B29 uses a switched-capacitor pipeline core with proprietary calibration to maintain linearity, while the front-end analog buffer provides a high-impedance differential input that tolerates a wide variety of source impedances. Differential LVDS outputs minimize switching noise on the digital supply rail, allowing the part to coexist with sensitive analog circuitry on shared 3.3V planes when proper decoupling is observed. Typical applications include multi-carrier GSM/EDGE base-station receivers, cable-headend digitizers, radar and SAR signal acquisition, test-and-measurement digitizer cards, and medical imaging front-ends. The integrated buffer and 250 MSPS throughput also suit software-defined radio (SDR) platforms that need wide instantaneous bandwidth at a moderate resolution. When designing with this device, drive the analog inputs differentially (typically through a balun or active differential amplifier) to achieve the datasheet's SFDR and SNR numbers at high input frequencies; the integrated buffer reduces but does not eliminate the sensitivity to common-mode noise at the analog inputs.

The Texas Instruments ADS61B49IRGZ25 is a 14-bit, 250-MSPS pipelined analog-to-digital converter with an integrated analog input buffer, housed in a 48-pin VQFN (RGZ) package measuring 7x7 mm. The device integrates an analog input buffer that eliminates the need for an external front-end driver, simplifying board design while delivering 250 MSPS sample rate with low power consumption. According to the TI datasheet, it operates from 1.8V to 3.3V analog and digital supplies and is specified over the industrial temperature range of -40C to +85C. An ADC (Analog-to-Digital Converter) is a mixed-signal integrated circuit that converts continuous analog waveforms into discrete digital codes at a defined sample rate. Pipelined ADCs use a multi-stage architecture to achieve high sample rates (hundreds of MSPS) with moderate resolution (10-16 bits), occupying a position in the signal chain hierarchy: sensor/buffer -> variable-gain amplifier -> ADC -> DSP/FPGA. The ADS61B49 belongs to TI's ADS61xx family of buffered-input, low-power data converters used in communications, test equipment, and industrial imaging. Key specifications include 14-bit resolution, 250 MSPS maximum sample rate, internal references eliminating the need for external reference decoupling capacitors, parallel/LVDS output interface, and an integrated input buffer that handles high source-impedance sensors directly. The 48-VQFN package provides an exposed thermal pad for low thermal resistance, supporting reliable operation across the full industrial temperature range. Architecturally, the device uses a multi-stage pipelined core with on-chip sample-and-hold and internal bandgap references. The input buffer isolates the switched-capacitor sampling front-end from external drive circuitry, improving SFDR/SNR performance when the source impedance is non-zero. The internal references remove layout sensitivity around external reference pins, a common pitfall in high-speed ADC designs. Typical applications include communications test equipment, multi-carrier GSM/UMTS/LTE base-station receivers, medical imaging front-ends, industrial ultrasound, and high-speed data acquisition systems. The buffered input makes it particularly suitable for direct connection to differential IF stages without an external op-amp driver. When designing with this device, allocate sufficient PCB area for the thermal pad and stitch vias to inner ground planes; route LVDS outputs with controlled 100-ohm differential impedance; and place input coupling capacitors and common-mode bias resistors as close to the analog input pins as the layout allows. Use a quiet, low-noise LDO such as the TPS7A4701 on the AVDD rail to maximize SFDR. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet. It is intended to accelerate sourcing and first-pass PCB decisions for engineers specifying a 250 MSPS buffered-input ADC.

The device features simultaneous sample-and-hold on both channels, 3.5 dB coarse gain, and 6 dB programmable fine gain, with no missing codes across the operating range. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples continuous analog voltages and converts them into discrete digital codes. Pipeline ADCs such as the ADS6223 family use a multi-stage switched-capacitor architecture to achieve sample rates from tens to hundreds of MSPS while maintaining low power consumption. ADCs sit in the signal chain hierarchy between analog front ends (amplifiers, filters) and digital processing blocks (FPGAs, DSPs, ASICs), and are essential in data acquisition, communications, and imaging systems where analog signals must be digitized for analysis or storage. The ADS6223IRGZR offers 12-bit resolution, programmable output data rates of 65/80/105/125 MSPS, a coarse gain of 3.5 dB and a programmable fine gain of up to 6 dB, and a serial LVDS output interface for low-noise board-level data transfer. Internally, two simultaneously-sampling track-and-hold stages feed a shared pipelined core that delivers deterministic latency suitable for I/Q demodulation. The device is specified over the industrial -40C to +85C temperature range and operates from a single 3.3 V analog and digital supply. Typical applications include medical imaging ultrasound front ends, multichannel industrial data acquisition cards, communications receiver I/Q baseband digitization, and handheld test and measurement instruments. The LVDS serial interface reduces board trace count compared to parallel CMOS ADCs, enabling dense multi-channel layouts on standard FR-4. When designing with this device, provide low-impedance decoupling on each supply pin and a quiet analog ground plane to achieve the rated SNR. The exposed thermal pad must be soldered to the PCB ground for both thermal dissipation and electrical reference; failing to solder the EP will degrade linearity and may cause device failure.

It integrates two simultaneously-sampling 12-bit ADCs capable of up to 105 MSPS per channel with no missing codes, plus an internal reference that can be overridden by an external source for improved absolute accuracy or ADC-to-ADC gain matching. The part is specified over the industrial temperature range of -40 °C to +85 °C, making it suitable for harsh-environment signal chains. A pipelined ADC is a high-speed data-converter architecture that resolves each input sample through a chain of low-resolution stages with digital error correction, delivering high sample rates (tens to hundreds of MSPS) at moderate resolution (8-14 bits). Pipelined ADCs sit higher than successive-approximation (SAR) ADCs in the speed/resolution trade-off but lower than flash ADCs in raw analog bandwidth; they are members of the broader data-converter IC family, which also includes delta-sigma, SAR, and flash topologies. The ADS6224 belongs to TI's high-speed converter portfolio targeting communications, instrumentation, and defense imaging subsystems. Key features include a maximum sample rate of 125 MSPS (the 105-MSPS grade shipped as IRGZ25 is pin-compatible with the 65/80/105/125 MSPS variants), simultaneous sample-and-hold for both channels, a 3.5 dB coarse gain option plus a 6 dB programmable fine gain, serialized LVDS output for low-EMI high-speed data transfer, and a 1.8 V analog / 3.3 V LVDS supply split. Total power dissipation is approximately 320 mW per channel at 105 MSPS, and the LVDS interface reduces board-routing complexity versus parallel CMOS outputs at >100 MSPS. The ADS6224 uses a multi-stage pipeline with an internal sample-and-hold and supports both single-wire and dual-wire LVDS serialization to flex with board density and FPGA capture budgets. Its LVDS topology generates far less switching noise than parallel CMOS outputs, easing EMI compliance in dense multi-channel systems such as 4G base-station receivers and phased-array radar digitizers. Typical applications include communications base-station receivers (multi-carrier GSM, LTE, WCDMA), multi-channel wireless infrastructure, medical imaging front-ends (ultrasound beamformers), defense and instrumentation (synthetic aperture radar, oscilloscope data acquisition), and dual-channel IF-sampling designs where both I and Q paths must be digitized concurrently with matched gain. When designing with this device, decouple AVDD (1.8 V) and LVDDR (3.3 V) supplies independently with 1 µF + 100 nF ceramic capacitors placed within 5 mm of the supply pins, and provide a solid low-impedance ground plane under the exposed thermal pad. Route the LVDS output pairs with 100 Ω differential impedance and length-match within 150 ps to minimize inter-symbol jitter at the FPGA receiver.

It supports input voltages of 3.3 V nominal and provides simultaneous sample-and-hold on both channels with a pipelined architecture and no missing codes at 12-bit resolution. An analog-to-digital converter (ADC) is a semiconductor device that converts continuous analog signals into discrete digital codes, enabling digital signal processing, storage, and transmission. High-speed ADCs sit at the boundary between the analog and digital domains and are critical for applications including communications infrastructure, medical imaging, defense electronics, and industrial test and measurement. The ADS6224 belongs to TI's high-speed ADC portfolio, where the LVDS (Low-Voltage Differential Signaling) interface family is preferred for low-noise, high-speed data transfer across PCB traces and into downstream FPGAs or ASICs. Key specifications include a maximum sample rate of 125 MSPS (with the ADS6224IRGZR specifically rated for 105 MSPS), 12-bit resolution, 3.5 dB coarse gain, 6 dB programmable fine gain, dual simultaneous sampling, and a 48-VQFN (HVQCCN) package. Industrial temperature grade -40 °C to +85 °C operation is supported. The pipelined core architecture multiplies per-channel sample rate while preserving low-latency conversion, and the integrated gain stages simplify front-end signal conditioning for inputs that exceed the ADC's full-scale range. The dual-channel simultaneous sampling and LVDS output make the ADS6224IRGZR well suited for communications baseband I/Q capture, ultrasound beamforming, and multi-channel instrumentation. The 105 MSPS per-channel rate supports IF sampling of signals in the tens of MHz and direct RF undersampling in some architectures. Programmable gain allows system designers to optimize dynamic range without external attenuators, and the LVDS output minimizes EMI by using differential signaling, which is essential in dense, multi-layer boards. Typical applications include communications receivers (baseband I/Q digitizers), medical ultrasound imaging front-ends, industrial digitizers and oscilloscopes, radar signal processing, and defense electronic warfare systems. When designing with this ADC, ensure the LVDS data and clock traces are length-matched (typically within 5-10 mils) and routed with controlled 100-ohm differential impedance. Decouple AVDD and DVDD supplies separately and provide a clean low-jitter clock to the CLK input to preserve SNR.

It features two simultaneously-sampling inputs, on-chip sample-and-hold, 3.5 dB coarse gain plus up to 6 dB programmable fine gain for SFDR/SNR trade-off, and serialized LVDS output with one-wire or two-wire modes for flexible board routing. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples a continuous-time analog waveform and produces a discrete binary code at its output. Pipelined ADCs, like the ADS6225, use a multi-stage architecture with per-stage residue amplifiers and digital error correction, enabling high sample rates (tens to hundreds of MSPS) while consuming moderate power. ADC products are a sub-category of data converters, which themselves sit within the broader mixed-signal / power-management IC hierarchy used in virtually every signal acquisition system. Key features include 12-bit resolution with no missing codes, simultaneous sample-and-hold on both channels, internal reference option, and an external reference mode for gain scaling. The serialized LVDS interface reduces parallel-digital switching noise on the board and simplifies timing closure at 125 MSPS. A 3.3 V analog supply with a separate digital I/O supply rail (DVDD) supports low-EMI integration with FPGAs. Industrial temperature range (-40C to +85C) and AEC-Q100-grade die pedigree make this family attractive for harsh-environment signal chains. Typical applications include multi-antenna wireless base-station receiver IF digitizers, medical ultrasound beamforming front ends, portable and bench-top oscilloscopes, dual-channel communications test equipment, and industrial imaging / vibration analysis. The wide SFDR/SNR gain tuning lets designers trade linearity for noise on a per-channel basis. When designing with this device, allocate a quiet analog ground plane and decouple AVDD with 1 uF plus 0.1 uF ceramics placed within 3 mm of each supply pin. The serialized LVDS link must be length-matched within 1 cm and terminated with 100 ohm differential at the FPGA bank. Verify FPGA LVDS-25/-33 bank compatibility before PCB commitment.

The Texas Instruments ADS6242IRGZR is a dual-channel, 14-bit, 65-MSPS analog-to-digital converter (ADC) with serial LVDS outputs, housed in a 48-pin VQFN (RGZ) 7x7 mm package. The ADS6242 family covers 125/105/80/65 MSPS sampling rates, and the IRGZRZ suffix identifies the 65 MSPS speed grade in tape-and-reel packaging on the 7x7 mm QFN footprint. Serial LVDS data outputs reduce the number of interface lines, enabling compact board layouts and high system integration density. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples continuous analog input signals and converts them into discrete digital codes at a specified sampling rate. High-speed ADCs such as the ADS6242 family sit at the front-end of the signal chain in communications infrastructure, medical imaging, defense electronics, and test-and-measurement equipment, where they digitize wideband IF or baseband signals for downstream DSP, FPGA, or ASIC processing. They are part of the broader pipeline-ADC architecture family, characterized by multi-stage sample-and-hold conversion that achieves high sample rates at moderate-to-high resolution. Key features of the ADS6242 include a 3.5 dB coarse gain option that improves SFDR (spurious-free dynamic range) performance with minimal SNR (signal-to-noise ratio) degradation, serial LVDS outputs that simplify PCB routing and reduce EMI, internal references that reduce external component count, and a 48-pin VQFN package providing excellent thermal performance. The dual-channel architecture with independent sample-and-hold circuits supports simultaneous sampling, critical for I/Q radio chains and beamforming applications. From an architectural perspective, the ADS6242 uses a pipelined multi-stage conversion core followed by digital error correction. The coarse gain option is implemented as an analog front-end attenuator that backs off the input signal below the converter's full-scale range, which pushes the signal away from the nonlinear regions of the input sampling network and improves large-signal SFDR. Typical applications include wireless communications basestation receivers, software-defined radio (SDR) platforms, medical ultrasound imaging front-ends, defense radar signal processing, and high-speed data acquisition systems. The dual-channel simultaneous sampling makes the ADS6242 ideal for I/Q demodulation, diversity reception, and multi-antenna systems. Designers should note that input common-mode voltage, clock jitter, and input bandwidth all directly impact achievable SNR - careful PCB layout and a low-jitter clock source are essential.

Key features include 14-bit resolution with guaranteed no missing codes, simultaneous sample-and-hold on both channels, 3.5 dB coarse gain plus up to 6 dB programmable fine gain for SFDR/SNR trade-off, serialized LVDS outputs that reduce pin count and ease board routing, internal reference with external reference support, and a 3.3-V analog/digital supply. The LVDS interface delivers data over a small number of differential pairs, minimizing EMI in dense multi-channel designs. Architecturally the device uses a switched-capacitor pipelined front end with on-chip reference buffer and integrated LVDS drivers. The simultaneous dual sample-and-hold simplifies front-end alignment for I/Q or diversity receivers, while the programmable gain allows per-channel SFDR optimization. According to the Texas Instruments datasheet, the pin-compatible 12-bit family is the ADS622X and the feature-compatible quad-channel family is the ADS644X/ADS642X. Typical applications include multi-channel wireless infrastructure receivers, medical imaging front ends, radar and sonar signal processing, and high-speed instrumentation. The wide input common-mode range down to 400 mVpp supports direct-IF sampling in cost-sensitive designs. When designing with this part, choose the input-driver op amp (e.g., THS4503 or OPA695) and anti-alias filter topology carefully because the 80 MSPS input bandwidth is well above the Nyquist limit and any front-end distortion directly degrades SFDR.

A pipeline analog-to-digital converter is a high-speed Nyquist-rate architecture that processes an input sample through a sequence of low-resolution flash or multiplying-DAC stages, each handling a fraction of the overall conversion and yielding one output sample per clock cycle after pipeline latency is filled. Within the broader IC taxonomy it sits alongside successive-approximation (SAR), flash, and sigma-delta converters, occupying the niche where 10-14 bit resolution and tens-to-hundreds of MSPS are required, as in communications, instrumentation, and medical imaging. Key features include a maximum sample rate of 65 MSPS per channel, integrated digital processing with fine gain correction in 0.05 dB steps, and a coarse 3.5 dB gain stage that lets the user trade dynamic range against SNR. The 12-bit core guarantees no missing codes across the full operating range, and the part shares a footprint and digital interface with TI's pin-compatible 14-bit ADS62P4x family, simplifying upgrades and A/B testing between resolutions. Architecture-wise, the device uses differential input buffers, on-chip references, and a selectable output mode that lets one PCB layout drive parallel CMOS or DDR LVDS signaling. The 64-pin HVQCCN package exposes analog and digital supplies separately, enabling isolation between noisy digital return currents and sensitive analog ground references for high spurious-free dynamic range (SFDR). Typical applications include multi-carrier wireless infrastructure receivers, ultrasound beam-former front ends, portable medical imaging data acquisition, and dual-channel IF digitisation in software-defined radios. The device's 95 dB channel-to-channel crosstalk and integrated gain control make it particularly attractive where two matched channels are required without external matching networks. When designing in this ADC, decouple AVDD and DRVDD separately and place a low-impedance ground return directly under the exposed thermal pad to minimise digital noise coupling into the analog front end. Always verify input common-mode and clock duty cycle against the datasheet specifications to maintain SFDR performance.

ADS62P23IRGC25 - Dual 12-bit 80MSPS ADC, DDR LVDS/CMOS | TI

The Texas Instruments ADS62P23IRGC25 is a dual-channel 12-bit analog-to-digital converter (ADC) with a maximum sample rate of 80 MSPS, housed in a 64-pin VQFN (RGC) package measuring 9x9 mm. The device integrates a high-performance pipeline architecture with selectable double-data-rate (DDR) LVDS or parallel CMOS output interfaces, giving designers flexibility to balance pin count, board area, and downstream FPGA/ASIC interface complexity. Internal references are included, which eliminates the traditional external reference pins and associated decoupling capacitors, while the device still supports an external reference drive when needed. An analog-to-digital converter (ADC) is a data-conversion IC that translates a continuous analog input voltage into a discrete digital code at each sampling clock edge. Within the signal chain taxonomy, the ADS62P23 belongs to the pipeline ADC sub-family, which sits between successive-approximation register (SAR) ADCs (low speed, low power) and flash ADCs (very high speed, high power). Pipeline ADCs dominate the 10-250 MSPS speed range because they multiplex many low-resolution stages behind a high-speed input, delivering high sample rates with moderate power budgets and small footprints. The ADS62P2X family specifically targets wideband communications, IF-sampling radios, and multi-channel industrial imaging. Key features include 80 MSPS guaranteed sample rate, 12-bit resolution across two simultaneously-sampled channels (2x2 channel matrix is supported via the family), and a wide analog input bandwidth of approximately 450 MHz. The integrated DDR LVDS interface delivers two data bits per clock cycle on each LVDS pair, halving the required FPGA pin count compared to parallel CMOS. Typical uses cover test and measurement digitizers, communications base-station receivers, medical ultrasound beamformers, and defense signal-intelligence capture cards. Industrial-grade -40C to +85C operation ensures deployment in uncontrolled enclosures. When designing with the device, prioritize short, matched-length traces between the analog inputs and the ADC; place the analog input RC network as close to the analog input pins as the layout allows to preserve SNR/SFDR. The combination of integrated references, selectable output interface, and the 9x9 mm VQFN footprint simplifies board layout versus older ADCs that required external references and LVDS buffers.
