ISL26712IHZ-T7A - 12-Bit 1MSPS SAR ADC | SOT-23-8 | Renesas
The Renesas ISL26712IHZ-T7A is a 12-bit, 1 MSPS successive-approximation-register (SAR) analog-to-digital converter housed in an 8-pin SOT-23 package. It accepts a single fully-differential input, operates from a 2.7 V to 5.25 V analog supply, and draws only 4.6 mW of power at 1 MSPS with a 5 V supply. The converter uses an SPI-compatible serial interface for configuration and data readout, allowing easy connection to microcontrollers, FPGAs, and DSPs in space-constrained designs. What is a SAR ADC? A successive-approximation-register analog-to-digital converter is a sampling ADC architecture that converts an input voltage to a digital code by performing a binary search against a precision internal DAC. SAR ADCs offer deterministic latency, low power consumption, and excellent linearity, making them the architecture of choice for industrial process control, multi-channel data-acquisition systems, battery-powered instrumentation, and precision sensor front-ends. They sit in the hierarchy of: ADC -> data converter -> mixed-signal IC -> semiconductor. Key features of the ISL26712IHZ-T7A include 1 MSPS sampling rate on a single channel, fully-differential input, internal oscillator, low 4.6 mW power at full throughput, and a single 2.7 V to 5.25 V supply. The 8-pin SOT-23 footprint is one of the smallest in this speed/resolution class and is well suited to tight sensor boards. The ISL26712IHZ-T7A shares its silicon with the 10-bit ISL26710 and 8-bit ISL26708 family members, and the -T7A suffix denotes a 250-piece tape-and-reel reel for prototyping and medium-volume assembly. The architecture uses a charge-redistribution DAC and on-chip sample-and-hold, achieving excellent AC and DC performance without an external reference bypass capacitor in most applications. Typical applications include industrial process control loops (4-20 mA inputs read through a resistor), portable medical instrumentation (electrochemical sensors, pulse oximeters), handheld test equipment, factory-automation sensor modules, and consumer audio front-ends. Differential inputs let designers reject common-mode noise picked up by long sensor cables. A key design trade-off to remember is that the ISL26712IHZ-T7A is single-channel and differential-only; systems requiring multiple single-ended channels should add an external analog MUX in front of the ADC. The SOT-23-8 thermal envelope is also small, so heat dissipation in high-temperature environments must be checked against the 4.6 mW dissipation at 1 MSPS with 5 V supply.

ISL267450AIHZ-T - 12-Bit 1MSPS SAR ADC | SOT-23-8 | Renesas
The Renesas ISL267450AIHZ-T is a 12-bit, 1 MSPS successive-approximation-register (SAR) analog-to-digital converter with one input channel, housed in a compact 8-pin SOT-23-8 package. Operating from a 2.7 V to 5.25 V analog supply, it delivers 12-bit resolution at up to 1 million samples per second, with industrial-grade screening from -40 C to +85 C. The device is drop-in pin-compatible with its 10-bit sibling ISL267440 within the same family. A SAR ADC is a type of data converter that uses a binary-search successive-approximation algorithm against an internal capacitive DAC to digitize an analog input. SAR ADCs occupy the middle ground between slow, high-accuracy delta-sigma converters and fast, lower-resolution flash converters, making them the workhorse for general-purpose industrial, instrumentation, and process-control sampling where both speed and precision matter in a small footprint. The ISL267450AIHZ-T features excellent linearity over supply and temperature variations, an integrated low-drift internal reference option, and a simple SPI-compatible serial interface that minimizes GPIO usage on the host microcontroller. Its SOT-23-8 footprint occupies roughly 9 mm² of board area, allowing it to be placed adjacent to the signal source for short, clean analog traces. The wide 2.7 V to 5.25 V supply range lets it accept a 3.3 V or 5 V rail directly, simplifying power-tree design. Typical applications include multi-channel data-acquisition front ends, sensor-signal digitization for industrial process control, portable instrumentation, and battery-management monitoring subsystems. Its combination of 1 MSPS throughput and 12-bit accuracy makes it a strong fit for sampling current-sense amplifiers, thermocouple-conditioned signals, and strain-gauge bridge outputs. When designing with this part, keep analog and digital ground returns separated and joined at a single point near the IC, and place the decoupling capacitor within 2 mm of the supply pin.

ISL267450AIHZ-T7A - 12-bit 1MSPS SAR ADC | Renesas | SOT-23-8
The Renesas (formerly Intersil) ISL267450AIHZ-T7A is a 12-bit, 1 MSPS successive-approximation register (SAR) analog-to-digital converter with one pseudo-differential input channel, housed in an 8-pin SOT-23 surface-mount package. The -T7A suffix indicates a 250-piece, 7-inch tape-and-reel packaging option qualified for industrial-temperature (-40C to +85C) operation, with the device delivering 1 Msamples per second conversion throughput from a single +4.75V to +5.25V analog supply and a separate 2.5V reference. What is a SAR ADC? A successive-approximation register analog-to-digital converter is a sampling ADC architecture that performs one conversion by comparing the sampled input against a binary-weighted reference ladder, bit-by-bit, in N clock cycles for N bits of resolution. SAR ADCs sit in the hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. They offer deterministic low-latency conversion (no pipeline delay), excellent DC linearity, and are well-suited for multiplexed data-acquisition, instrumentation, and process-control front-ends where both DC accuracy and clean dynamic performance are required. Key features of the ISL267450AIHZ-T7A include 12-bit no-missing-codes performance, an integrated input track-and-hold, a high-speed SPI-/QSPI-/MICROWIRE-compatible serial interface, and excellent linearity over supply and temperature variations. The pinout is drop-in compatible with the ISL267440 (10-bit version), enabling system-level resolution scaling without PCB rework. The device accepts an external reference up to VDD, allowing designers to optimize dynamic range against the input signal amplitude. The ISL267450AIHZ uses a charge-redistribution SAR core with an auto-zeroing input front end to minimize offset and drift. It includes a serial data-output clock edge that simplifies isolated-barrier or opto-coupled data-acquisition front ends. The single 5V supply rail simplifies system power, while the small SOT-23-8 footprint suits compact, dense PCB layouts where conventional QFN or SOIC ADC packages are too large. Typical applications include industrial process-control analog input modules, multi-channel data-acquisition systems, portable battery-powered instrumentation, optical-sensor front ends, and precision sensor-signal digitization. Its wide operating range and small package also fit medical-monitoring accessory boards and energy-monitoring (energy-harvesting metering) designs. A key design consideration is reference decoupling: place a low-ESR 10 uF tantalum or ceramic bypass directly on the REF pin with a 0.1 uF ceramic in parallel to preserve linearity at 1 MSPS. Route the digital outputs away from the analog input traces to minimize digital-coupling noise; even though the SOT-23 package keeps the part compact, the input signal integrity and reference stability dictate achievable SNR. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found in the bare manufacturer datasheet, giving engineers a single source for comparing 12-bit, 1 MSPS SAR ADCs from Renesas, Texas Instruments, and Analog Devices in the SOT-23-8 footprint.
ISL267450AIUZ-T - 12-Bit 1MSPS SAR ADC | Renesas | MSOP-8
The Renesas ISL267450AIUZ-T is a 12-bit, 1 MSPS successive-approximation-register (SAR) analog-to-digital converter in an 8-pin MSOP package. It features a single-ended analog input, an SPI/QSPI/MICROWIRE-compatible serial interface, and excellent linearity over supply and temperature variations. The part operates from a 2.7 V to 5.25 V analog supply, draws only 4.2 mW at 1 MSPS with a 3 V supply, and is offered in the -40 °C to +85 °C industrial temperature range. A SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that performs a binary search through successive bit trials to resolve an analog input into a digital code. SAR ADCs sit in the broader hierarchy of data converter -> ADC -> Nyquist-rate converter -> SAR architecture, where they are valued for zero-latency conversion, low power consumption, and deterministic behavior, making them a preferred choice for multiplexed data acquisition and precision industrial sensing. Key features of the ISL267450AIUZ-T include a 12-bit resolution with no missing codes, a single 2.7 V to 5.25 V supply, an SPI/QSPI/MICROWIRE-compatible serial data interface, an integrated track-and-hold amplifier, and very low power dissipation. Per the manufacturer datasheet, the device is drop-in pin-compatible with the AD7450A from Analog Devices, simplifying migration paths for new and existing designs. Architecturally, the ISL267450AIUZ-T combines a charge-redistribution DAC with a high-speed comparator and SAR control logic on a single CMOS die. The internal reference voltage is 2.5 V, while the analog input accepts a 0 V to VREF unipolar range. Power-down current drops to 1 µA between conversions, an important figure for battery-operated instruments that sample on demand. Typical applications include remote industrial sensors, battery-powered instrumentation, portable data loggers, and process control front ends. The combination of 1 MSPS throughput, low power, and small MSOP-8 footprint also makes it attractive for medical patient monitoring and energy harvesting sensor nodes. When designing with this ADC, allocate at least one 10 nF bypass capacitor close to the AVDD pin and route the analog and digital grounds as a star-connected pattern to avoid code-dependent noise coupling. Because it is a 1 MSPS SAR, settle the input amplifier to better than 12-bit accuracy within the acquisition window. This page synthesizes distributor pricing, drop-in compatible alternatives, and engineering design guidance not found in a single source - useful for engineers who need to evaluate, qualify, and second-source the ISL267450AIUZ-T in production designs.

It operates from a single 2.7V to 5.25V supply, supports a -40C to +85C industrial temperature range, and is specified as a drop-in replacement for the AD7450. A SAR ADC is a successive-approximation-register analog-to-digital converter that uses a binary-search algorithm against an internal DAC to resolve each conversion in N clock cycles for an N-bit output. SAR ADCs occupy the middle ground between flash ADCs (fast, power-hungry, expensive) and sigma-delta ADCs (slow, very high resolution). They are favored in industrial data acquisition, motor control feedback loops, and instrumentation where single-shot latency, deterministic sampling, and moderate sample rates (100kSPS to 10MSPS) are required. The ISL267450IUZ-T7A sits in the 1MSPS class - the workhorse rate for multiplexed multi-channel systems. Key features include 12-bit resolution with no missing codes, 1MSPS throughput, differential input range of 2*VREF, integrated reference, SPI/QSPI/MICROWIRE-compatible serial interface, and low power dissipation (typically under 10mW at 1MSPS). The device maintains excellent linearity over supply and temperature variations, with integral nonlinearity (INL) and differential nonlinearity (DNL) performance that suits precision measurement. The MSOP-8 footprint is pin-compatible with the legacy AD7450 and the AD7450A, simplifying board-level substitution. Typical applications include industrial process control, multi-channel data acquisition systems, portable instrumentation, battery-powered monitoring, and motor control position feedback. The 2.7V to 5.25V supply range covers both 3.3V and 5V analog rails found in mixed-signal embedded designs. When designing with the ISL267450IUZ-T7A, observe the datasheet's input common-mode and reference decoupling guidelines. A 10uF tantalum plus 0.1uF ceramic bypass network close to the supply pin is recommended for low-noise operation. The serial interface timing budget must allow for 13 SCLK cycles per conversion at full throughput.

ISL267452IHZ-T7A - 12-Bit 555kSPS SAR ADC | Renesas
The Renesas ISL267452IHZ-T7A is a 12-bit, 555 kSPS successive-approximation-register (SAR) analog-to-digital converter in an 8-pin SOT-23 package. Per the Renesas datasheet, the part features a single-ended/fully-differential input, operates from a 2.7 V to 5.25 V analog supply, and is rated for the -40 C to +85 C industrial temperature range. The -T7A suffix denotes a 250-piece tape-and-reel packing option aimed at low-volume prototyping and small production runs. A SAR ADC is a successive-approximation-register analog-to-digital converter. It uses an internal binary-search algorithm with a single comparator and a charge-redistribution DAC to digitize an analog input one code at a time, achieving excellent DC accuracy and very low latency (one conversion cycle) compared to delta-sigma or pipelined converters. SAR ADCs belong to the data-converter family alongside delta-sigma ADCs, pipeline ADCs, and flash ADCs, and they sit inside the broader mixed-signal IC hierarchy under signal conditioning and data acquisition. Key features include 12-bit resolution with no missing codes, 555 kSPS throughput, low power consumption of approximately 5.2 mW at 555 kSPS, an SPI/QSPI/MICROWIRE-compatible serial interface, and true-differential analog inputs that maintain specified accuracy for input signals up to the supply rails. The high-impedance analog input structure minimizes leakage-induced errors in high-impedance source applications such as sensor front-ends. The architecture is based on a charge-redistribution SAR core with on-chip track-and-hold. Renesas states the part is pin-compatible with the legacy AD7452 from Analog Devices, allowing it to serve as a drop-in second-source. The single-supply 2.7 V minimum operation makes it well suited to 3.3 V and 5 V microcontroller-based systems without requiring additional negative rails. Typical applications include industrial process control, portable instrumentation, data acquisition systems, battery-powered monitoring, and optical sensor front-ends. The combination of small SOT-23-8 footprint, 555 kSPS speed, and 12-bit accuracy makes it ideal where board area is constrained and full pipeline ADC speed is not required. When designing with this part, ensure the analog input common-mode voltage stays within the specified range and provide a low-impedance reference (such as a 10 uF ceramic bypass on REF) to avoid conversion noise. The SOT-23-8 thermal envelope is more than adequate for the 5.2 mW dissipation, so no special thermal management is needed. This page synthesizes distributor pricing from DigiKey, Mouser, and Octopart, drop-in and same-package alternatives, and practical design notes for the ISL267452 family that go beyond what is in the manufacturer datasheet alone.
ISLA212P20IRZ - 12-Bit 200MSPS SAR ADC, 72-QFN | Renesas
The Renesas (formerly Intersil) ISLA212P20IRZ is a 12-bit, 200 MSPS successive-approximation-register (SAR) analog-to-digital converter that delivers high dynamic performance at low power. It is part of the pin-compatible ISLA212P family built on Intersil's proprietary FemtoCharge™ technology on a standard CMOS process, allowing sampling rates up to 250 MSPS, 200 MSPS, and 130 MSPS variants from a single 72-contact QFN (10 mm x 10 mm) footprint with an exposed thermal paddle. What is a SAR ADC? A successive-approximation-register analog-to-digital converter is a sampling converter that uses a binary-search algorithm against a precision DAC to resolve the input voltage one bit per clock cycle. SAR ADCs sit in the data-converter hierarchy as ADC -> Nyquist/oversampling ADC -> mixed-signal IC -> semiconductor. They offer excellent linearity, deterministic latency, and low power compared to flash or pipeline converters at moderate sample rates, making them well-suited to instrumentation, communications baseband, and wideband test equipment. Key headline specifications of the ISLA212P20IRZ include 12-bit resolution, 200 MSPS sampling rate, LVDS/CMOS-selectable digital outputs, SPI configuration port, and -40 °C to +85 °C industrial operating range. The device supports both single-data-rate (full-width SDR) and double-data-rate (half-width DDR) output modes, giving system designers flexibility for FPGA, ASIC, or DSP capture. A 72-contact QFN package with an exposed paddle supplies a low thermal-resistance path for high-clock full-rate operation. Architecturally, the part uses FemtoCharge™ switched-capacitor input sampling and an internal high-precision reference, with optional external reference support. Its pipeline-style latency is deterministic and pipelined-friendly, simplifying FPGA capture at multi-hundred-megasample rates. Gain, offset, and output timing are adjustable through the SPI port, supporting per-channel calibration in multi-board systems. Typical applications for the ISLA212P20IRZ include wideband test and measurement instruments, radar IF/baseband digitizers, communications receiver baseband I/Q capture, medical imaging front-ends, and high-channel-count data-acquisition systems. The combination of 12-bit resolution, 200 MSPS throughput, and low power suits portable and ruggedized platforms where thermal density must be controlled. Designers should provide adequate ground and decoupling on the analog and digital rails, follow the exposed-paddle soldering recommendations (see manufacturer application layout), and verify SPI configuration timing during bring-up. When migrating between family members, no PCB rework is required.

ISLA214P12IRZ - 14-Bit 125MSPS SAR ADC | Renesas Electronics
The Renesas Electronics (formerly Intersil) ISLA214P12IRZ is a 14-bit, 125 MSPS successive-approximation-register (SAR) analog-to-digital converter delivering very high dynamic range and low power consumption, packaged in a 72-pin QFN (10x10 mm). The part offers 1 differential input channel with unbuffered (switched-capacitor) analog inputs and is part of a pin-compatible family of 12- to 16-bit ADCs with sample rates from 125 MSPS to 500 MSPS, allowing a single PCB layout to migrate across resolution and speed grades. A SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm implemented with a capacitive DAC and a high-speed comparator to resolve each conversion in N clock cycles for N-bit resolution. SAR ADCs are valued for their deterministic latency, single-shot accuracy, and excellent dynamic performance, and they sit at the leaf of the broader data-converter hierarchy: SAR ADC -> A/D converter -> data acquisition IC -> signal chain -> mixed-signal semiconductor. The ISLA214P12 uses a high-performance, low-power core that is well suited for instrumentation, communications and imaging front ends where both speed and DC accuracy matter. Key differentiating features include 125 MSPS maximum sampling rate, 14-bit resolution, 1.8 V/3.3 V supply operation, LVDS/LVCMOS-compatible digital outputs, and an internal reference. The 72-QFN (10x10) package provides a low thermal-resistance path and is footprint-compatible with the wider ISLA214P/ISLA216P/ISLA214S/ISLA216S family, so a single PCB layout can be reused across multiple performance tiers. The device also integrates an input common-mode clamp and a self-calibrating background circuit that maintains DC accuracy over temperature. The pin-compatible family approach means a system designed around the ISLA214P12IRZ can be re-populated with ISLA214P25, ISLA214P50 or higher-resolution members (ISLA216P25/ISLA216P50) when additional sample rate or resolution is required, with no PCB changes. This is particularly valuable for multi-product platforms where one design must address multiple market tiers. Typical applications include communications test equipment, radar and signal-intelligence front ends, medical imaging (ultrasound beamformers), high-speed data acquisition cards, and industrial imaging. Designers favor the ISLA214P12IRZ when very high dynamic range, low latency and pin-compatible scalability across the ISLA214P/ISLA216P family are required within a 72-QFN footprint. When designing with this converter, pay close attention to the analog-input network: a wide-band, low-distortion differential driver (such as the ISL552xx or ADA4937 family) must present the proper common-mode voltage and source impedance to the unbuffered switched-capacitor inputs. Decouple each supply pin individually with 100 nF ceramic capacitors placed as close as possible to the package, and provide a solid ground plane under the exposed pad to minimize digital switching noise coupling into the analog front end. This page synthesizes distributor pricing, drop-in same-brand and cross-brand alternatives, and practical design notes (clock, input network, decoupling, exposed-pad soldering) not found in a single place in the manufacturer datasheet, giving engineers a faster starting point for ISLA214P12IRZ-based designs.
ISLA214P25IRZ - 14-Bit 250MSPS ADC, 72-QFN | Renesas
The Renesas ISLA214P25IRZ is a 14-bit, 250 MSPS low-power high-performance analog-to-digital converter (ADC) with one input channel, housed in a 72-contact QFN (10x10 mm) package with an exposed thermal paddle. It uses Renesas' proprietary FemtoCharge™ switched-capacitor technology on a standard CMOS process to deliver high dynamic performance at sample rates up to 250 MSPS, and operates from a single 1.8 V supply over the -40 °C to +85 °C industrial temperature range. An ADC (analog-to-digital converter) is a data-conversion integrated circuit that quantizes a continuous-time analog input signal into a discrete digital code at a specified sampling rate. High-speed pipeline ADCs such as the ISLA214P25IRZ sit in the signal chain between the analog front end (amplifier / filter / driver) and a downstream FPGA, ASIC, or DSP, where they convert wideband IF or baseband signals into digital words. The ISLA214P25IRZ occupies the "ADC -> data converter IC -> data acquisition -> signal chain IC" hypernym in the power-management and mixed-signal taxonomy and is widely used in communications, defense electronics, and test-and-meeasurement equipment. Key specifications include 14-bit resolution, 250 MSPS maximum sampling rate, SPI/serial configuration interface, selectable LVDS or CMOS digital outputs configurable as full-width single-data-rate (SDR) or half-width double-data-rate (DDR), and a 72-lead QFN-EP (10x10 mm) package. The converter is part of a pin-compatible 12-bit to 16-bit Renesas FemtoCharge™ ADC family that scales from 130 MSPS to 500 MSPS, simplifying board-level migration. A serial peripheral interface (SPI) port provides extensive configurability, including fine control of gain and offset. Architecturally, the part uses a multi-stage pipeline core that is interleaved with on-chip calibration logic; FemtoCharge™ technology reduces the reset-noise kick usually associated with switched-capacitor gain stages, improving SFDR and SNR at high input frequencies. Digital output data can be routed through a flexible LVDS/CMOS interface, allowing the same device to drive an FPGA in SDR (1 data line per channel) or DDR (½-width) mode, which simplifies board-level data capture at multi-hundred-megasample rates. Typical applications include communications receivers (LTE, WiMAX, multi-carrier GSM/EDGE base stations), radar and EW systems, medical imaging, high-speed data acquisition cards, and bench-top instrumentation. The wide input bandwidth and configurable digital interface make it equally suited to single-channel IF sampling and to multi-channel diversity receiver sub-systems. According to the Renesas datasheet FN6510, the device is part of a larger pin-compatible family so customers can re-use the same PCB footprint to scale resolution (12/14/16 bit) and sample rate (130/200/250 MSPS) as system requirements evolve. A key design consideration is power-supply decoupling and LVDS-termination strategy: each LVDS output pair must be DC-terminated with a 100 Ω differential resistor at the FPGA receiver, and a low-noise LDO (e.g. a TPS7A47-class part) should power the AVDD rail. Designers should also confirm that the FPGA IDDR/ISERDES block supports the selected SDR/DDR mode and that the input drive amplifier meets the part's 1.5 V p-p full-scale input requirement with adequate linearity at the highest input frequency of interest. This page synthesizes distributor pricing, pin-compatible Renesas FemtoCharge™ family alternatives, and practical layout and SPI-programming design notes not found in the manufacturer datasheet alone.
ISLA216S13IR1Z - 16-Bit 130MSPS JESD204B ADC | Renesas
The Renesas ISLA216S13IR1Z is a 16-bit, 130 MSPS analog-to-digital converter with a JESD204B-compliant high-speed serial output, housed in a 48-pin QFN (7x7 mm) package. Designed on Intersil's proprietary FemtoCharge technology in a standard CMOS process, this SAR-pipelined ADC delivers low-power, high-performance conversion suitable for communications, instrumentation, and defense signal chains. The serial interface reaches up to 4.375 Gbps per lane and uses two lanes in this 16-bit, single-channel configuration. An analog-to-digital converter (ADC) is an integrated circuit that converts continuous analog signals into discrete digital codes, forming the critical boundary between the analog and digital domains in mixed-signal systems. ADC architectures include SAR (successive approximation register), pipelined, sigma-delta, and flash; the ISLA216S family uses a pipelined architecture with SAR-style backend, which balances high sampling speed with multi-MHz analog input bandwidth. The 16-bit class sits at the upper end of resolution for high-speed converters, enabling very low quantization noise floor. Key features of the ISLA216S13IR1Z include 130 MSPS sampling rate (with up to 250 MSPS and 500 MSPS speed grades available in the same family), 16-bit resolution, 1 input channel, JESD204B serial output with deterministic latency, and pin compatibility with 12-bit and 14-bit family members (ISLA212S, ISLA214S). The device supports configurable packing modes and offers multi-chip time alignment via the JESD204B subclass-1 features. Operating temperature spans -40 C to +85 C (industrial grade), with the R1Z suffix denoting the tape-and-reel packaging option. From a digital-system perspective, the JESD204B serial link eliminates the wide parallel CMOS/ LVDS data bus that traditionally constrained high-speed ADC board layout, instead using a serialized link that greatly reduces board-routing density and simplifies FPGA pin-count planning. The FemtoCharge architecture minimizes sample-and-hold charge injection and reduces aperture uncertainty, resulting in excellent SNR at high input frequencies - critical in radar, broadband communications, and digital oscilloscope front-ends. Typical applications include multi-carrier GSM/UMTS/LTE base-station receivers, cable-infrastructure digitization, radar and electronic-warfare signal capture, test and measurement instrumentation, and medical imaging front-ends such as ultrasound beamformers. The 130 MSPS grade is well suited to intermediate IF sampling in software-defined radio (SDR) platforms and to high-channel-count phased-array antenna systems where deterministic latency is mandatory. When integrating the ISLA216S13IR1Z into a PCB, allocate a continuous ground plane beneath the exposed pad, route the JESD204B lanes as 100-ohm differential pairs with length matching to within a few millimeters, and keep the analog input traces short and surrounded by ground. Decouple AVDD and DVDD rails independently at the pins with low-ESL ceramic capacitors. Verify the FPGA's JESD204B IP core supports the chosen lane count and lane rate before final BOM lock.
ISLA216S25IR1Z - 16-Bit 250MSPS JESD204B ADC | Renesas
The Renesas (formerly Intersil) ISLA216S25IR1Z is a 16-bit, 250 MSPS, high-speed analog-to-digital converter with a JESD204B-compliant high-speed serial output, fabricated in a standard CMOS process using Renesas FemtoCharge™ technology. Housed in a 48-pin LQFN (Hawk) package, it delivers state-of-the-art dynamic performance for demanding wideband signal-chain applications. What is a high-speed JESD204B ADC? A high-speed analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time analog signal at high rates (tens to hundreds of MSPS) and outputs a discrete digital word for downstream processing. When the data interface uses the JESD204B standard (JEDEC standard for serial data conversion interfaces), the converter streams its digital output over a small number of high-speed serial lanes, eliminating parallel LVDS routing and reducing PCB complexity. The ISLA216S25 family belongs to the broader category of pipeline ADCs (successive pipeline architecture) within the data-converter market segment. Key headline specifications include 16-bit resolution, 250 MSPS maximum sample rate, JESD204B serial interface, low-latency digital processing, integrated input buffer / output drive, and configurable lane counts. The FemtoCharge™ architecture minimises aperture uncertainty and provides clean spurious-free dynamic range (SFDR) when driven by demanding wideband IFs. Typical applications for this ADC family include digital oscilloscopes, wideband communication test equipment, software-defined radio (SDR) platforms, radar and lidar receivers, medical imaging front-ends (ultrasound beamforming), and spectrum analysers. The serial JESD204B interface makes it well-suited to FPGA-based processing pipelines such as those built on Xilinx Kintex/Vertex and Intel/Altera Stratix families. A critical design consideration when using this part is matched impedance routing of the JESD204B serial lanes; reference clock jitter at sub-picosecond levels is required to realise 16-bit noise floor performance. The internal input bandgap and reference structure are calibrated at the factory, so designers only need to provide clean low-noise analog and clock supplies.

The Renesas (formerly Intersil) ISLA222P20IRZ is a dual-channel 12-bit analog-to-digital converter from the ISLA222P family, supporting a maximum sampling rate of 200 MSPS and housed in a 72-pin QFN (10x10 mm) package with an exposed thermal pad. The device implements Intersil's proprietary FemtoCharge™ technology on a standard CMOS process, enabling high dynamic performance with low power dissipation suitable for communications, medical imaging, and defense signal-chain applications. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts a continuous-time analog voltage into a discrete digital code, acting as the critical bridge between the analog physical world and a digital processor. ADCs are grouped by architecture (SAR, pipeline, sigma-delta, flash) and resolution/speed trade-off; high-speed pipeline ADCs like the ISLA222P20 target the bandwidth tier where flash is impractical and SAR cannot keep pace, sitting within the broader mixed-signal and data-converter IC hierarchy. Key features of the ISLA222P20IRZ include 12-bit resolution across two simultaneous sampling channels, 200 MSPS maximum conversion rate, parallel CMOS or LVDS digital output interfaces, and an SPI-configurable port for gain, offset, and mode control. The FemtoCharge™ switched-capacitor architecture delivers excellent SNR/SFDR for IF-sampling receivers, while the integrated input buffer and on-chip reference simplify board-level design. The ISLA222P is part of a pin-compatible portfolio spanning 12-bit and 14-bit dual ADCs with sample rates from 130 MSPS to 250 MSPS, allowing designers to scale performance without changing the PCB footprint. Internal calibration logic maintains performance across temperature, and the exposed-pad QFN package provides low thermal resistance for the moderate power dissipation typical of the family's operating point. Typical applications include cellular base-station receive paths, radar and EW digitizers, portable instrumentation, medical ultrasound receivers, and high-speed data acquisition systems. Designers choose the ISLA222P20IRZ when they require dual simultaneous sampling at IF with low spurious content in a compact surface-mount footprint. When designing with this device, ensure the analog inputs are AC-coupled or DC-biased within the common-mode range specified in the datasheet, and provide low-impedance ground returns on the exposed pad for thermal and electrical performance. Use the SPI port to optimize gain and offset for each channel independently.

The Renesas KAD2710C-17Q68 is a 10-bit, 170 MSPS, single-channel pipelined analog-to-digital converter in a 68-lead QFN (10x10 mm) exposed-pad package. It is the 170 MSPS speed grade of the KAD2710C family, which also offers 105, 210 and 275 MSPS variants, and the -17Q68 part number designates the LVCMOS-compatible output variant in the QFN-68 package. A pipelined ADC (analog-to-digital converter) is a high-speed data converter architecture that resolves an analog input through multiple cascaded low-resolution stages, each driving a residue into the next. Compared with successive-approximation or flash converters, pipelined ADCs deliver the best balance of sampling rate, resolution, power dissipation, and input bandwidth, which is why they dominate communications infrastructure, instrumentation, and imaging. The KAD2710C family is the industry's lowest-power 10-bit pipelined ADC at 275 MSPS, consuming under 265 mW with 55.6 dBFS SNR at fIN = 138 MHz, built on Renesas' proprietary FemtoCharge technology in a standard CMOS process. The KAD2710C-17Q68 integrates a selectable divide-by-2 input clock buffer, an over-range indicator for gain ranging, and an internal reference. Its LVCMOS outputs interface directly with FPGAs and ASICs at speeds up to 170 MSPS, while the exposed-paddle QFN-68 package provides low thermal resistance (theta-JA of approximately 24 C/W) suitable for industrial-temperature operation from -40C to +85C. The 1.8 V analog and 3.3 V output supply domains simplify interfacing with modern FPGA I/O without level translators. Typical applications include digital oscilloscopes, communication test equipment, IF sampling in software-defined radio, radar signal processing, medical imaging front-ends, and high-speed data acquisition cards. The 170 MSPS sampling rate easily covers intermediate-frequency bands up to 70 MHz while leaving headroom for input-bandwidth-limited anti-alias filtering. Designers should ensure the exposed paddle is soldered to a continuous ground plane and that the analog input is AC-coupled with 50 ohm-controlled impedance to realize the published ENOB and SFDR performance.
KAD2710C-21Q68 - 10-Bit 210MSPS ADC | Intersil (Renesas) | QFN-68
The Renesas (formerly Intersil) KAD2710C-21Q68 is a 10-bit, 210 MSPS, single-channel, high-performance analog-to-digital converter (ADC) in a 68-pin QFN (10x10 mm) package with an exposed thermal pad. It belongs to the KAD2710C pin-compatible ADC family, which offers 8- and 10-bit resolutions and sample rates from 105 to 350 MSPS. The KAD2710C-21Q68 variant is the 210 MSPS speed grade with LVCMOS-compatible digital outputs. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous analog input voltages into discrete digital codes at a specified sampling rate. High-speed ADCs like the KAD2710C sit between the analog front-end (amplifiers, filters, mixers) and the digital back-end (FPGA, ASIC, DSP) in signal acquisition systems. They are the critical bridge that determines the dynamic range, bandwidth, and fidelity of any digital receiver, oscilloscope, or radar processing chain. ADC performance is commonly characterized by SNR (signal-to-noise ratio), SFDR (spurious-free dynamic range), ENOB (effective number of bits), and aperture jitter. The KAD2710C-21Q68 leverages Intersil's proprietary FemtoCharge™ technology on a standard CMOS process to achieve 55.6 dBFS SNR at an input frequency of 138 MHz while consuming less than 265 mW. Key features include an integrated over-range indicator, a selectable divide-by-2 input clock buffer, an internal reference, and LVCMOS output drivers. The 68-pin QFN package provides an exposed paddle for low thermal resistance, allowing operation across the industrial temperature range of -40°C to +85°C. Architecture is a pipelined multi-stage ADC with on-chip sample-and-hold and internal bandgap reference, supporting single-ended analog inputs. The pipelined architecture delivers high sample rates at moderate power consumption compared to flash or successive-approximation designs. Typical applications include digital oscilloscopes, IF sampling in communications receivers, radar signal processing, medical imaging front-ends, and high-speed data acquisition cards. The wide input bandwidth supports undersampling architectures for IF digitization. When designing with this device, ensure the analog input is properly terminated and that the input clock has low jitter (< 1 ps RMS) to preserve SNR at high input frequencies. Decouple all supply pins with 0.1 µF and 10 µF capacitors placed as close to the package as possible, and tie the exposed paddle to a clean ground plane.
