HI3-574AJN-5Z - 12-Bit 40kSPS SAR ADC w/ 10V Ref | Renesas
HI3-574AJN-5Z

HI3-574AJN-5Z - 12-Bit 40kSPS SAR ADC w/ 10V Ref | Renesas

The Renesas HI3-574AJN-5Z is a complete 12-bit successive-approximation analog-to-digital converter (SAR ADC) that integrates a +10V buried-zener voltage reference, an internal clock, three-state output buffers, and a parallel microprocessor-compatible interface on a single 28-pin PDIP. The part is rated for 40 kSPS throughput and operates from dual ±12V to ±15V analog supplies plus a single +5V digital supply. Two monolithic dice are co-packaged inside the 28-lead PDIP: a bipolar analog die built on Intersil's dielectric-isolation process and a CMOS digital die. An SAR (Successive Approximation Register) ADC is a class of Nyquist-rate data converter that resolves each sample by performing one binary-weighted comparison per clock cycle against an internal DAC. SAR ADCs sit in the hierarchy: ADC -> Nyquist ADC -> successive-approximation ADC -> data converter -> mixed-signal IC. They offer the best trade-off between speed (kSPS to MSPS), resolution (8-18 bits typical), and power dissipation (no continuous current like in delta-sigma or pipelined ADCs), which is why they remain the dominant topology for 12-bit instrumentation front-ends and legacy microprocessor data-acquisition boards. Key features of the HI3-574AJN-5Z include 12-bit resolution with ±1/2 LSB linearity (typical), a true bipolar ±10V or unipolar 0-10V/0-20V analog input range (selected by pin strapping), a buried-zener reference with low 10 ppm/°C typical drift, internal clock oscillator (no external component required), and three-state output buffers that allow direct connection to 8-bit or 16-bit microprocessor buses. The integrated reference and clock minimize external BOM, while the dielectric-isolation bipolar process reduces digital feedthrough into the analog input. Typical applications include industrial process-control loops, multi-channel data-acquisition boards (front-end ADC for microprocessors such as 8086, 68K, Z80), precision instrumentation, legacy avionics retrofit, and medical monitoring front-ends. The 28-PDIP package is through-hole and remains popular for prototype boards, educational lab equipment, and replacement of obsolete AD574A sockets. When designing with this device, note that the converter requires a minimum 2 µs acquisition time and a 1.5 µs conversion cycle; layout-sensitive applications should bypass VCC/VEE pins with 10 µF tantalum + 0.1 µF ceramic capacitors placed within 1 cm of the IC pins. The analog and digital grounds should be tied only at one star point to avoid ground-loop-induced offset drift.

HI3-674AKN-5 - 12-Bit SAR ADC, 67 ksps, 28-PDIP | Renesas
HI3-674AKN-5

HI3-674AKN-5 - 12-Bit SAR ADC, 67 ksps, 28-PDIP | Renesas

The Renesas HI3-674AKN-5 (originally Harris Semiconductor, then Intersil) is a complete 12-bit successive-approximation analog-to-digital converter (SAR ADC) with an industry-standard +/-10 V or 0-10 V / 0-20 V input range, integrated +10 V reference, three-state outputs, and a digital interface designed for direct connection to 8-bit or 16-bit microprocessors. The converter is housed in a 28-pin plastic DIP (28-PDIP) package and is specified for the -5 commercial / industrial speed grade. According to the HI-X74 datasheet, the part delivers up to approximately 67 ksps throughput and consumes less than 100 mW of power from a single +5 V supply. A SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm implemented with a successive-approximation register and an internal DAC. SAR converters sit within the broader ADC taxonomy (SAR -> medium-speed ADC -> data converter -> mixed-signal IC -> semiconductor). They are favored over flash, sigma-delta, and pipeline architectures in multiplexed data-acquisition systems that require low latency, deterministic conversion time, good DC accuracy, and modest sample rates (tens to hundreds of ksps) - making them ideal for industrial process control, instrumentation, and front-end signal conditioning. Key specifications of the HI3-674AKN-5 include 12-bit resolution with no missing codes, an internal buried-Zener +10 V reference (calibrated for low drift), bipolar input ranges of +/-5 V, +/-10 V, 0-10 V, and 0-20 V (configurable per the original AD574A pinout standard), and three-state output buffers for direct bus connection. The -5 speed grade provides a conversion time on the order of approximately 15 microseconds, and the device operates over the commercial temperature range of 0C to +70C. Architecturally, the HI3-674AKN-5 is implemented as two monolithic dice housed inside a single 28-lead package: one die contains the 12-bit DAC, reference, and analog signal-conditioning circuitry, while the second die contains the successive-approximation register, three-state output latches, and microprocessor control logic. The converter uses an industry-standard pinout and control interface originally popularized by the Analog Devices AD574A, allowing it to be a drop-in replacement in many legacy designs. Typical applications include industrial process-control front ends, multiplexed 4-20 mA / 0-10 V data-acquisition systems, portable instrumentation, and battery-cell monitoring front ends. Designers select the HI3-674AKN-5 when they need a proven bipolar-input 12-bit ADC with on-board reference and a microprocessor-friendly parallel interface. When designing with this device, pay attention to input signal conditioning: a buffer amplifier (such as an AD711 or OP27) and an external RC antialias filter are typically recommended at the analog input. Decoupling of the +5 V VCC and +15 V/-15 V supplies with 10 uF tantalum in parallel with 0.1 uF ceramic caps placed close to the supply pins is essential for stable reference performance. Ensure that the digital interface mode (8-bit / 12-bit / standalone) matches your microprocessor data-bus width before assigning chip-enable logic.

HI3026JCQ - 8-Bit 120 MSPS Flash ADC | Renesas | 48-MQFP
HI3026JCQ

HI3026JCQ - 8-Bit 120 MSPS Flash ADC | Renesas | 48-MQFP

The Renesas Electronics (formerly Intersil) HI3026JCQ is an 8-bit, 120 MSPS flash analog-to-digital converter with a single analog input channel, housed in a 48-lead Metric Quad Flat Pack (MQFP, 12x12 mm). Designed for high-speed digital signal acquisition, this converter samples at up to 120 million samples per second, providing the throughput required for video digitisation, IF sampling in communications receivers, and instrumentation front-ends. A flash ADC (also known as a parallel A/D converter) is a data-conversion architecture in which a bank of 2^N-1 comparators simultaneously quantises the input voltage against a precision resistor ladder, producing an N-bit code in a single clock cycle. Flash converters sit at the top of the ADC performance hierarchy by offering the lowest latency and highest sampling rates of any ADC topology, at the cost of higher power consumption and larger die area as resolution increases. The HI3026JCQ belongs to the broader category of data-converter ICs and is widely deployed where sub-microsecond acquisition latency is critical. Key specifications of the HI3026JCQ include its 8-bit native resolution, 120 MSPS maximum conversion rate, single-ended analog input, and CMOS-compatible digital outputs that interface directly with FPGAs, ASICs, and standard logic families. The device operates from a single supply and integrates an internal reference network, simplifying the analog front-end. Its 48-pin MQFP (12x12 mm) package provides robust mechanical reliability for industrial and military-temperature designs and supports through-hole-style surface-mount assembly. Architecturally, the HI3026JCQ employs a fully parallel comparator array, a precision thin-film resistor ladder, and an integrated output register, delivering a one-clock-cycle conversion delay. This makes the device ideal for time-interleaved systems, digital oscilloscopes, radar digitizers, and medical imaging front-ends where deterministic latency matters more than absolute DC accuracy. Typical applications include digital video processing and baseband sampling in software-defined radios, where the 120 MSPS sampling rate comfortably exceeds common IF bandwidths, and in radar/sonar pulse digitisation. It is also used in military/aerospace telemetry acquisition and as a low-latency digitiser in industrial inspection cameras. When designing with the HI3026JCQ, pay careful attention to analog input bandwidth and impedance matching. Use a high-bandwidth op-amp driver and a properly terminated transmission line for the analog input to avoid aperture jitter; route the digital outputs as a controlled-impedance bus with damped terminations to limit simultaneous-switching noise (SSN). According to the Renesas/Intersil datasheet, adequate decoupling (0.1 uF + 10 uF near each supply pin) is required to maintain ADC linearity at full sampling rate. This page synthesises distributor stock status, drop-in alternatives, application context, and practical design notes not found in any single source on the web, helping engineers evaluate, source, and design with the HI3026JCQ more efficiently.

HI5662/6IN - Dual 8-Bit 60MSPS ADC | Renesas Electronics
HI5662/6IN

HI5662/6IN - Dual 8-Bit 60MSPS ADC | Renesas Electronics

The Renesas Electronics (formerly Intersil / Harris) HI5662/6IN is a monolithic dual 8-bit 60 MSPS analog-to-digital converter fabricated in an advanced CMOS process, delivered in a 44-pin MQFP (PQFP44, 10x10 mm) package. It integrates two complete 8-bit ADCs, an internal bandgap voltage reference, and output data latches on a single die, achieving a level of multi-channel integration aimed at high-speed data acquisition systems. The dual-channel architecture allows simultaneous sampling of two analog inputs at up to 60 MSPS per channel from a single +5 V supply while consuming only 650 mW total. Input configurations include both single-ended and fully differential modes, selected by input stage innovation in the pipeline design. An 8-bit analog-to-digital converter (ADC) is a data converter IC that samples a continuous analog signal and produces an 8-bit digital code representing the instantaneous signal amplitude. As a dual-channel pipelined ADC, the HI5662/6IN fits within the broader hierarchy of successive-approximation-register (SAR) and pipeline ADCs, both of which sit under the larger umbrella of data-converter ICs and, ultimately, mixed-signal semiconductor devices. Pipeline ADCs deliver multi-MSPS to GSPS sample rates with low latency, making them the dominant architecture for high-speed video, communications IF, and pulsed waveform capture. Key differentiating specifications include 60 MSPS maximum sample rate per channel, 8-bit resolution across two channels, an internal voltage reference eliminating external reference components, single +5 V power supply operation, and 6-clock-cycle output latency. The output latches present valid data to the output bus deterministically, simplifying downstream FPGA or ASIC capture. The advanced CMOS process delivers excellent dynamic performance suitable for both time-domain and frequency-domain instrumentation. The CMOS pipeline architecture uses a multi-stage switched-capacitor design where each stage resolves a portion of the bits and passes the residual to the next stage. This approach enables high sample rates while keeping per-stage power consumption low; the total 650 mW figure at 60 MSPS confirms the efficiency of the chosen architecture relative to flash or folding ADCs of similar speed. Internal reference stability is maintained by an on-chip bandgap cell with low temperature drift. Typical applications include digital oscilloscopes and waveform digitizers, IF signal processing in communications receivers, medical imaging front-ends, radar pulse processing, and any instrumentation requiring simultaneous dual-channel analog capture with deterministic latency. When designing with this part, pay close attention to analog input common-mode biasing and clock jitter; the 60 MSPS conversion rate imposes approximately 17 ps RMS of allowable clock jitter for full ENOB preservation. Power-supply decoupling should use a 0.1 uF ceramic capacitor in parallel with a 10 uF tantalum or polymer cap placed close to the AVDD pin. The MQFP-44 footprint provides more than enough thermal margin for the 650 mW dissipation.

HI5714/4CBZ - 8-Bit 40MSPS ADC, 24-SOIC | Renesas
HI5714/4CBZ

HI5714/4CBZ - 8-Bit 40MSPS ADC, 24-SOIC | Renesas

The Renesas HI5714/4CBZ is an 8-bit, 40MSPS analog-to-digital converter (ADC) fabricated in Intersil's advanced HBC10 BiCMOS process, housed in a 24-pin SOIC (W) commercial-temperature package. Per the Renesas product brief, the converter targets high-precision applications including ultrasound imaging, mass storage, instrumentation, and video digitizing, and is available in speed grades of 40 / 60 / 75 / 80 MSPS, with the "/4" suffix denoting the 40 MSPS grade. An 8-bit ADC is a data conversion integrated circuit that quantizes a continuous analog input into 256 discrete digital codes (2^8), with sampling speed expressed in MSPS (mega-samples per second). The HI5714/4CBZ uses a 2-step folding-and-interpolating architecture, a classical high-speed ADC topology that minimizes comparator count and die area compared with full-flash designs while delivering tens-of-MHz conversion rates. Positioned inside the broader hierarchy, the part belongs to ADC -> data converter -> signal-chain IC -> mixed-signal semiconductor. Key differentiating features include differential analog inputs with an internal bandgap reference, low power consumption suitable for portable and rack-mounted imaging systems, CMOS-compatible parallel digital outputs that interface directly with DSPs and FPGAs, and a single 5V analog supply operation. The 2-step folding architecture inherently supplies low differential non-linearity (DNL), which is critical for clean ultrasound echo reconstruction and instrumentation-grade measurements. From an architecture perspective, the HBC10 BiCMOS process blends bipolar transistors (for high-speed analog front-ends) with CMOS logic (for low-power digital decoding), allowing the converter to reach 40MSPS without sacrificing digital efficiency. The internal reference and input common-mode bias network simplify board-level BOM, while the parallel byte-wide output bus is formatted for direct connection to image processing ASICs and FPGA-based acquisition cards. Typical applications for the HI5714/4CBZ include medical ultrasound front-end digitizers, professional video frame grabbers and SDTV/HDTV capture cards, industrial data acquisition modules, and IF/RF digitizing in instrumentation receivers. The 40MSPS conversion rate comfortably digitizes standard-definition analog video (4x oversampling of a 27 MHz video bandwidth) and supports I/Q baseband sampling in software-defined radio receivers. When designing with the HI5714/4CBZ, treat the analog input as a differential pair and follow the manufacturer's recommended footprint and decoupling topology. Switch-mode regulators on the analog rail should be avoided near the converter, as residual switching noise within tens of MHz can fold back into the ADC bandwidth and degrade SNR.

HI5714/7CB-T - 8-Bit 75MSPS ADC | Renesas | SOIC-24

The Renesas HI5714/7CB-T is a 8-bit, 75 MSPS (Mega Samples Per Second) monolithic analog-to-digital converter fabricated in Intersil's advanced HBC10 BiCMOS process, housed in a 24-pin SOIC (Small Outline IC, gull-wing) package. The device supports four user-selectable sample rates of 40 / 60 / 75 / 80 MSPS and delivers low-power operation with a single +5 V analog supply. The 8-bit resolution and 75 MSPS default rate place this part in the mid-speed video-flash ADC category. What is an 8-bit flash ADC? A flash analog-to-digital converter (flash ADC) is the fastest ADC architecture, using 2^N - 1 parallel comparators to convert an analog input to a digital code in a single clock cycle. An 8-bit flash ADC therefore uses 255 comparators plus encoding logic, yielding conversion latencies of a few nanoseconds. The HI5714/7CB-T belongs to the hierarchy: ADC -> flash ADC -> video-speed ADC -> high-precision 8-bit data converter -> semiconductor IC. Flash ADCs dominate where latency matters more than absolute resolution - exactly the trade-off this Renesas part targets. Key features include 40/60/75/80 MSPS selectable sampling rates, on-chip 2.5 V reference, a binary output coding, low input capacitance (~7 pF), and the HBC10 BiCMOS process for low-noise switched-capacitor input track-and-hold. The architecture integrates the track-and-hold, reference, and 8-bit flash quantizer into one monolithic die. Technically, the device draws roughly 165 mW from +5 V at 75 MSPS, supports TTL-compatible outputs, and includes an internal bandgap reference for the resistor ladder. The wide sample-rate selector lets one PCB handle video standards from NTSC to XGA without re-spun silicon. Typical applications include ultrasound imaging front-ends, mass-storage read channels, video digitizing capture cards, and general-purpose instrumentation digitizers. Its speed makes it suitable for undersampling IF signals in communications test gear as well. When designing with this part, ensure the analog input is properly clamped, bypass the supply with a 100 nF plus 10 uF capacitor pair, and treat the SOIC-24 thermal pad with adequate ground copper for noise-sensitive layouts.

The Renesas HI5746KCAZ is a monolithic 10-bit analog-to-digital converter fabricated in a CMOS process, offering 40 MSPS sampling rate and CMOS-compatible outputs in a 28-pin SSOP package. According to the manufacturer datasheet, the device combines a fully differential pipelined architecture with an internal sample-and-hold, achieving up to 40 MSPS conversion while maintaining low power consumption suitable for portable and high-density designs. The pipelined architecture delivers 10-bit resolution at high throughput with deterministic latency, while the CMOS output drivers simplify direct interfacing with FPGAs, ASICs, and standard microprocessors without external level translation. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete binary codes for digital processing. Within the broader taxonomy, the HI5746 belongs to the pipeline ADC subclass of Nyquist-rate data converters, situated above flash ADCs (faster but lower resolution), successive-approximation-register (SAR) ADCs (lower speed, higher accuracy), and delta-sigma ADCs (oversampling-based high resolution). Pipeline ADCs are ideal for applications requiring 8-14 bits of resolution at conversion rates from 10 MSPS to several hundred MSPS, occupying a key position in the data-converter hierarchy. Key features of the HI5746KCAZ include 40 MSPS maximum sampling rate, single +5V analog supply operation, an internal sample-and-hold front-end that eliminates the need for external track-and-hold circuitry, and CMOS outputs that drive standard 3.3V/5V digital loads. The differential pipeline topology reduces even-order harmonics and improves common-mode noise rejection, which is critical in communications and imaging front-ends. Internal voltage reference and amplifier circuitry reduce the external BOM while preserving low aperture jitter for accurate sampling of fast signals. Typical applications include digital video processing, IF sampling in communications receivers, CCD digitizers, medical imaging arrays, ultrasound beamformers, and baseband signal acquisition in software-defined radio. The 40 MSPS throughput comfortably handles component video (up to 27 MSPS for standard definition), instrument data acquisition, and intermediate-frequency subsystems in cable, satellite, and terrestrial set-top boxes. When designing with this ADC, provide well-decoupled analog and digital supplies, place input series resistors and decoupling capacitors close to the analog input pins, and route the CMOS output bus away from sensitive analog traces. Maintain a stable, low-jitter encode clock and an adequate input anti-alias filter to preserve SFDR performance.

The 40 MSPS sampling rate is made possible by a fully differential pipelined architecture that consumes only 225 mW at full speed. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete digital codes at a defined sample rate. Within the broader taxonomy, the HI5746KCB is a pipelined successive-approximation-style ADC -> data converter -> mixed-signal IC -> semiconductor. Pipelined ADCs like the HI5746KCB trade slightly higher latency for high throughput and small die area, making them ideal for digitizing wideband IF, video, and instrumentation signals in the 1-100 MHz range. Key features of the HI5746KCB include a single differential or single-ended analog input, a 10-bit parallel CMOS output bus with a 7-clock-cycle latency, excellent dynamic performance, and pin-for-pin functional compatibility with the legacy HI5702 and HI5703 10-bit ADCs.

Key features of the HI5746KCBZ-T include 10-bit resolution, 40 MSPS sampling rate, fully differential analog input path for wide bandwidth, CMOS-compatible digital outputs, single-supply operation, and an internal reference arrangement. According to the Renesas product page, the part is pin-for-pin functionally compatible with the older HI5702 and HI5703, simplifying migration of legacy designs. The pipelined architecture delivers consistent ENOB (effective number of bits) across the input frequency range, and the CMOS outputs interface directly with modern FPGAs and DSPs without level translation. Typical applications include digital oscilloscopes, IF-sampling communications receivers, medical ultrasound imaging, CCD scanners, and industrial instrumentation. The 225 mW power budget is competitive for battery-portable test equipment, and the 7-cycle deterministic latency simplifies system-level timing closure in real-time DSP pipelines. When designing with this part, ensure the analog input is AC- or DC-coupled through a wideband driver (such as a current-feedback op-amp) capable of settling within the 25 ns sample window. Provide solid ground planes under the package and place the input driving network within a few millimetres of the analog input pins to preserve SNR.

HI5762/6IN - Dual 10-Bit 60MSPS ADC, 44-MQFP | Renesas

The Renesas HI5762/6IN is a monolithic dual 10-bit, 60 MSPS analog-to-digital converter built in an advanced CMOS process and housed in a 44-pin MQFP package. According to the Renesas datasheet, the device is designed for high-speed applications where integration, bandwidth, and accuracy are essential, integrating two independent 10-bit 60 MSPS ADC cores on a single die. What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage converter architecture that uses several low-resolution flash stages connected in series, with each stage sampling and converting a coarse slice of the input before passing the residue to the next stage. Compared to successive-approximation (SAR) or simple flash converters, pipelined ADCs deliver the highest sample rates (tens to hundreds of MSPS) at moderate resolution, making them the workhorse of digitizing wideband intermediate-frequency (IF) signals, video, and baseband communications. The HI5762/6IN is part of the broader analog-to-digital converter product hierarchy (ADC → pipelined ADC → high-speed CMOS ADC → data acquisition IC). Key features include dual 10-bit resolution, 60 MSPS maximum sample rate per channel, CMOS-compatible digital outputs, an internal voltage reference (eliminating the need for an external reference and saving PCB area), low power consumption typical of CMOS ADC designs, and built-in analog input clamping. The two converters share a common reference but have independent analog inputs, clock inputs, and digital output buses, allowing simultaneous sampling of two signals. Architecturally, the HI5762/6IN combines two cores of the HI5767 single-channel 10-bit 60 MSPS ADC, sharing only the on-chip bandgap reference and common supply pins. This level of integration reduces board area, lowers system cost, and improves channel-to-channel matching versus a discrete two-ADC solution. The advanced CMOS process contributes to low power dissipation and high digital integration density. Typical applications include high-speed data acquisition systems, medical imaging front-ends, IF sampling in communications receivers, professional video digitizers, and test-and-measurement instrumentation such as digital oscilloscopes and arbitrary waveform digitizers. The dual-channel nature is particularly suited to I/Q baseband sampling, diversity receiver paths, and dual-antenna or phased-array signal capture. When designing with the HI5762/6IN, pay particular attention to clock jitter: the analog input bandwidth and 60 MSPS sample rate require a low-jitter (sub-ps) clock source to preserve SNR. Ensure analog inputs are AC-coupled or properly biased within the common-mode input range, and place the internal reference bypass capacitor as recommended in the datasheet to minimize digital-noise feed-through.

HI5762/6INZ - Dual 10-Bit 60MSPS ADC w/Internal VREF | Renesas

The Renesas (formerly Intersil) HI5762/6INZ is a monolithic, dual 10-bit, 60 MSPS analog-to-digital converter fabricated in an advanced CMOS process, supplied in a 44-pin MQFP (10x10 mm) package. The /6 suffix designates an annealed part variant optimized for radiation-tolerant and high-reliability applications, while the INZ suffix indicates the industrial operating temperature range. The device integrates two fully pipelined 10-bit ADC cores along with an internal voltage reference, eliminating the need for external reference components in most designs. What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage architecture that converts analog signals to digital codes by passing the input through a cascade of low-resolution stages, each producing a partial conversion and feeding a residue to the next stage. Compared with flash or successive-approximation (SAR) ADCs, pipelined converters deliver much higher sampling rates (tens to hundreds of MSPS) at moderate resolution (8-14 bits), making them the workhorse of high-speed data acquisition. The HI5762 sits in the ADC -> data converter -> data acquisition IC -> signal processing semiconductor taxonomy. Key features of the HI5762/6INZ include 60 MSPS sampling rate per channel (dual simultaneous sampling), 10-bit resolution, internal 2.5 V bandgap voltage reference, CMOS-compatible digital outputs, low power consumption (typical 200 mW per channel at 60 MSPS), and a wide analog input bandwidth that supports IF undersampling. The pipelined architecture provides inherent sample-and-hold behavior on each channel, simplifying front-end driver design. Architecturally, the HI5762 combines two cores of the HI5767 single-channel 10-bit 60 MSPS ADC into a single die. This integration halves board space and improves channel-to-channel matching for I/Q demodulation, dual-antenna diversity receivers, and correlated multi-channel instrumentation. The internal reference eliminates the drift and noise issues of external references, though external reference operation is supported for applications requiring absolute accuracy. Typical applications include communications base-station receivers, digital oscilloscopes, medical imaging front-ends, radar signal processing, and high-speed instrumentation. The simultaneous dual-channel sampling makes the HI5762/6INZ particularly well suited for I/Q quadrature demodulation in software-defined radio (SDR) and diversity reception. When designing with this ADC, route analog and digital grounds separately and join them at a single point under the IC's exposed pad (where present). The 44-MQFP package has moderate thermal resistance; airflow is recommended when both channels sample at 60 MSPS continuously in enclosed enclosures.

HI5766KCA - 10-Bit 60MSPS ADC, 28-SSOP | Renesas

The Renesas HI5766KCA is a monolithic 10-bit, 60 MSPS analog-to-digital converter fabricated in a CMOS process, packaged in a 28-pin SSOP/QSOP. It is engineered for high-speed signal acquisition where wide analog bandwidth and low power consumption are essential, with the part dissipating approximately 260 mW at maximum conversion rate. The converter uses a fully differential pipelined architecture with an internal sample-and-hold, delivering 60 megasamples per second of throughput. A pipelined ADC is a converter architecture that processes an analog input through multiple cascaded low-resolution stages, each stage resolving a few bits and passing a residual to the next stage. This allows much higher sampling rates than successive-approximation or flash architectures while consuming moderate power. Within the data-converter hierarchy, pipelined ADCs sit between high-speed flash ADCs and high-resolution sigma-delta ADCs, and are commonly deployed in communications, imaging, and instrumentation front ends. Key features of the HI5766KCA include 10-bit resolution, 60 MSPS maximum sampling rate, single +5 V analog supply operation, CMOS-compatible digital outputs, internal sample-and-hold, and an analog input bandwidth that supports undersampling IF applications. The differential pipeline topology provides good common-mode noise rejection and stable dynamic performance over temperature. A single-ended or differential analog input can be driven, and the output data is presented as parallel CMOS words suitable for direct connection to an FPGA or DSP. Typical applications include digital video processing, IF sampling in communication receivers, CCD imaging front ends, ultrasound beamforming, and general-purpose high-speed data acquisition. The wide input bandwidth allows the converter to be used in undersampling schemes where the input frequency exceeds half the sampling rate, a common technique in intermediate-frequency digitizers. When designing with the HI5766KCA, ensure the analog input is driven with a low-impedance, bandwidth-matched amplifier and that the +5 V supply is well-decoupled close to the device. A/D converters running at 60 MSPS are sensitive to clock jitter; use a low-jitter crystal or PLL-derived clock source for best signal-to-noise ratio.

The Renesas HI5766KCAZ is a monolithic 10-bit analog-to-digital converter fabricated in a CMOS process, sampling at 60 MSPS with fully differential pipelined architecture and an internal sample-and-hold. It is housed in a 28-pin SSOP (28-SSOP) surface-mount package, designed for high-speed applications where wide bandwidth and low power consumption are essential. Power consumption is rated at 260 mW typical at the maximum 60 MSPS conversion rate. An ADC (analog-to-digital converter) is a data converter that transforms a continuous-time analog input voltage into a discrete digital output code, forming the boundary between the analog and digital signal domains. Within the broader product hierarchy, the HI5766 is a high-speed pipelined ADC, a sub-category of Nyquist-rate data converters that achieve fast sample rates through multi-stage pipeline architectures with per-stage residue amplification. Pipelined ADCs sit alongside successive-approximation-register (SAR) and flash ADCs in the data-converter taxonomy, all belonging to the wider class of mixed-signal and data acquisition ICs used in instrumentation, communications, and imaging systems. Key features of the HI5766KCAZ include a 10-bit resolution, 60 MSPS maximum sampling rate, single +5 V analog supply operation, fully differential analog input for high common-mode rejection, an external reference input, a parallel CMOS digital output bus, and a single analog input channel. The pipelined architecture provides 1 sample per clock cycle of latency, ideal for continuous streaming rather than multiplexed acquisition. According to the Renesas datasheet, the device consumes only 260 mW and maintains good dynamic performance at full conversion speed. Typical applications include flat-panel display digitizers, set-top box video digitizers, professional video broadcast equipment, IF (intermediate-frequency) sampling for communications receivers, medical ultrasound beamformers, and high-speed instrumentation. The wide analog input bandwidth and low power make the HI5766KCAZ attractive for portable imaging and battery-powered test equipment. When designing with the HI5766KCAZ, ensure the analog input is AC-coupled or DC-biased within the common-mode range of the differential input, place the reference decoupling capacitor directly at the REFT/REFB pins, and provide a clean low-jitter clock at the encode input to preserve SNR.

HI5766KCB - 10-Bit 60MSPS CMOS ADC | Renesas | 28-SOIC

The Renesas HI5766KCB is a monolithic 10-bit analog-to-digital converter fabricated in a CMOS process, delivering up to 60 MSPS sampling rate in a 28-pin SOIC (Wide) package with CMOS digital outputs. It is designed for high-speed applications where wide bandwidth and low power consumption are essential, and its 60 MSPS throughput is made possible by a fully differential pipelined architecture with an internal sample-and-hold. The differential pipeline topology rejects common-mode noise on the analog inputs and supports single-ended operation with an external reference. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous analog voltage and produces a discrete digital code proportional to the input level. Within the broader taxonomy, the HI5766KCB is a successive-stage pipelined ADC, a sub-type of Nyquist-rate data converters that sit between precision SAR ADCs (slow, high-resolution) and flash ADCs (fast, low-resolution). Pipelined ADCs occupy the middle ground: they offer high sampling rates (tens to hundreds of MSPS) at moderate resolution (8-14 bits) by cascading low-resolution stages, each stage producing a residue amplified for the next conversion stage. The HI5766KCB inherits this pipelined architecture but adds an internal sample-and-hold and CMOS-compatible digital outputs to simplify host interface design. Key features include 60 MSPS maximum sampling rate, 10-bit resolution, single 5V analog supply operation, CMOS digital outputs, internal sample-and-hold, and a fully differential analog input path. The pipelined architecture provides low latency and excellent spurious-free dynamic range for IF-sampling applications. Power dissipation is typically modest for the speed class, and digital outputs are directly compatible with 5V or 3.3V logic families depending on the supply configuration. Typical applications include professional video digitisation, IF sampling in communications receivers, digital oscilloscope front-ends, medical imaging preprocessing, and CCD/camera pixel array readout. The 10-bit resolution and 60 MSPS throughput are well-suited to standard-definition broadcast video (ITU-R BT.601) and intermediate-frequency undersampling in digital radio designs. When designing with this device, ensure the analog input common-mode voltage is biased within the converter's input range and that the external reference decoupling is low-ESR. PCB layout should keep analog input traces short and symmetrical, with a dedicated ground plane under the analog section to preserve spurious-free dynamic range.

The Renesas / Intersil HI5766KCBZ is a monolithic 10-bit, 60 MSPS analog-to-digital converter fabricated in a CMOS process, housed in a 28-pin SOIC wide-body package. Its headline parameters are 10-bit resolution at 60 MSPS sampling with a fully differential pipelined architecture, an internal sample-and-hold, and approximately 260 mW power dissipation. The converter is pin-for-pin functionally compatible with the legacy HI5702, HI5703, and HI5746 ADCs, easing legacy board reuse. An ADC (analog-to-digital converter) is a semiconductor device that samples a continuous-time analog signal and quantizes each sample into a binary code at a defined sample rate. ADCs sit in the signal chain between an analog front-end (amplifiers, filters, muxes) and a digital processor (DSP, FPGA, microcontroller). High-speed pipelined ADCs such as the HI5766KCBZ deliver many bits per sample at rates from tens to hundreds of MSPS and are a sub-class of data converters under the broader power management / mixed-signal hierarchy. Key differentiating features of the HI5766KCBZ include 10-bit resolution at 60 MSPS, low 260 mW power consumption for its speed class, CMOS output levels for direct interface to 3.3 V / 5 V logic, output data latches with 7-clock-cycle latency, and a fully differential pipelined core with internal sample-and-hold that simplifies analog front-end design. For internal voltage reference variants the datasheet points the reader to the HI5767 family. Architecturally, the HI5766KCBZ uses a fully differential switched-capacitor pipeline that delivers one conversion per clock cycle after the initial pipeline latency, with output latches presenting valid data 7 clocks later. The internal sample-and-hold minimizes aperture uncertainty and front-end drive requirements, while CMOS outputs eliminate the need for external level shifters when interfacing to common ASICs and FPGAs at 3.3 V. Typical applications for the HI5766KCBZ include professional video digitizers, medical imaging front-ends, set-top box and IF sampling chains, instrumentation and oscilloscope input stages, and communications receivers where moderate dynamic range at low power is required. It fits wherever a 10-bit, 60 MSPS CMOS ADC is the right speed/resolution trade-off. A key design consideration is that the HI5766KCBZ is pin-for-pin compatible with the older HI5746 family, so engineers migrating legacy 10-bit designs can re-use existing PCB footprints; however, where an internal voltage reference is required, the HI5767 should be evaluated instead.

The part integrates an internal voltage reference, a high-bandwidth track-and-hold, and a parallel CMOS-compatible digital interface, simplifying digital-IF, video, set-top box, and instrumentation designs that previously required a separate reference IC. An analog-to-digital converter (ADC) is a data-acquisition component that converts a continuous analog input signal into a discrete digital code suitable for processing by a microprocessor, FPGA, or DSP. Within the broader signal chain, the ADC sits between the analog front end (amplifiers, filters, and multiplexers) and the digital back end, and it is a critical sub-category of data converters (ADCs/DACs). 10-bit pipeline ADCs such as the HI5767 target applications where 60-66 dB of dynamic range is adequate and where low power and high integration matter more than 14- or 16-bit precision. The headline specifications of the HI5767/2CA include 10-bit resolution, a 20 MHz guaranteed sampling rate (40/60 MSPS variants exist in the same family), CMOS-process construction, an internal 2.5 V voltage reference, and a low-power architecture suitable for portable and industrial applications. The flash-style architecture and parallel word access deliver low-latency conversion suitable for digital-oscilloscope, CCD imaging, and IF-sampling subsystems. The HI5767/2CA is fabricated in a low-power CMOS process and uses a pipelined multi-stage architecture with on-chip sample-and-hold, enabling wide analog input bandwidth and fast settling time. An integrated reference minimizes external BOM, while parallel CMOS outputs reduce interface complexity in FPGA or ASIC capture paths. The combination of 10-bit resolution and 20 MSPS throughput makes the part well-suited to communication, video, and instrumentation subsystems where cost-effective integration matters more than extreme dynamic range. Typical applications for the HI5767/2CA include digital video acquisition, set-top box front ends, CCD imaging digitizers, ultrasound beam-formers, digital oscilloscopes, IF-sampling communication receivers, and industrial data-acquisition boards. The wide input bandwidth and integrated reference also make the converter attractive for low-power portable instrumentation and for medical imaging pre-processing pipelines. When designing with the HI5767/2CA, pay close attention to analog input drive, reference decoupling, and clock jitter. The 10-bit pipeline architecture tolerates modest source impedance, but an input buffer is recommended when driving the ADC from a high-impedance front end.

It targets high-speed applications where wide analog bandwidth and low power consumption are essential, integrating a high-bandwidth track-and-hold and an internal voltage reference on-chip. Speed grades are pin-strapped through the /2CB suffix indicating the 40 MSPS variant of the family. An analog-to-digital converter (ADC) is a data-acquisition component that converts continuous-time analog signals into discrete digital codes at a fixed sample rate, enabling downstream digital signal processing. Within the broader signal-chain hierarchy, the HI5767/2CB sits between analog conditioning (amplifier / filter) and the digital processor (DSP / FPGA / MCU); it is an example of a successive-approximation-class and pipelined converter used in interface and mixed-signal subsystems. The part belongs to the Data Acquisition family of integrated circuits, in the sub-domain of high-speed ADC interface ICs. Key features include 10-bit resolution, sample rates of 20/40/60 MSPS via speed-grade selection, CMOS process for low power dissipation (typical 150 mW at 40 MSPS), a 250 MHz analog input bandwidth, and an internal 2.5 V reference that may be overridden by an external reference for absolute accuracy. The architecture yields differential nonlinearity of ±0.4 LSB and integral nonlinearity of ±0.8 LSB. The on-chip pipeline architecture interleaves sample-and-hold stages with low-resolution flash sub-ADCs and a digital error-correction block, achieving low-latency conversion suitable for single-shot or repetitive capture. The CMOS implementation gives the part low glitch energy and good aperture timing, important for undersampling applications.

Typical applications for the HI5767/2CB include high-speed instrumentation, digital oscilloscopes, IF/baseband signal conversion in communications equipment, medical imaging front-ends, and CCD/CIS imaging pipelines. Cable equalization, radar baseband capture, and machine-vision frame-grabber front-ends also benefit from its 60 MSPS capability and integrated reference. Designers should pay attention to input-common-mode and clock-dither performance: the analog input must see proper termination and a 50 ohm shunt, and the encode clock should be driven with low-jitter LVTTL/CMOS levels. Decoupling the analog and digital supplies independently is recommended to maintain spurious-free dynamic range.

It features a pipelined architecture, single analog input channel, and parallel word output, designed for high-speed applications where wide bandwidth and low power consumption are essential per the manufacturer datasheet. What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage converter that uses several low-resolution sub-ADCs and DACs in cascade to achieve higher overall resolution at high sampling rates. Pipelined ADCs sit between successive-approximation (SAR) ADCs and flash ADCs in the converter hierarchy, offering the best trade-off between speed, resolution, and power dissipation for sample rates between a few MSPS and a few hundred MSPS, dominating the 8-to-16-bit, 10-to-200 MSPS market. Key features of the HI5767/4CA include selectable 20, 40, or 60 MSPS operation, integrated bandgap voltage reference, CMOS-compatible digital inputs, low-power CMOS process, and analog input bandwidth suitable for IF undersampling. The part supports single +5V analog supply operation per the datasheet, and its 28-SSOP/QSOP package provides a compact footprint for instrumentation and communications designs. The pipelined architecture delivers 10-bit resolution with no missing codes and differential nonlinearity within +/-1 LSB typical. The CMOS sub-micron process enables the HI5767/4CA to combine wide analog input bandwidth (specifying suitability for undersampling applications above Nyquist) with low power dissipation, making it well-suited for battery-powered or thermally constrained systems. The internal reference eliminates external reference components and reduces PCB area while simplifying power-supply design. Typical applications include digital oscilloscopes, IF sampling for communications receivers, CCD imaging front-ends, medical ultrasound front-ends, and radar/sonar baseband digitizers. The selectable sample rate (20/40/60 MSPS) lets one hardware platform cover multiple end-product SKUs without redesign. When designing with this part, ensure analog and digital grounds are separated at the IC and joined at a single point to preserve SFDR. Decouple AVDD and DVDD independently with 0.1 uF ceramic capacitors placed as close to the pins as possible. Source-impedance matching at the analog input is critical for full-bandwidth performance.

HI5767/4CAZ - 10-Bit 40MSPS ADC, CMOS, 28-SSOP | Renesas

The Renesas HI5767/4CAZ is a monolithic 10-bit analog-to-digital converter (ADC) fabricated in a CMOS process, sampling at up to 40 MSPS in a 28-pin SSOP/QSOP package with internal voltage reference. It supports single +5V analog supply operation and delivers pipelined, fully-differential conversion architecture with on-chip sample-and-hold and bandgap voltage reference. An analog-to-digital converter (ADC) is a data-acquisition integrated circuit that converts real-world analog signals into discrete digital codes for processing by microcontrollers, DSPs, FPGAs, or ASICs. The HI5767 family sits in the converter hierarchy as follows: ADC -> data converter -> data-acquisition IC -> mixed-signal semiconductor. Pipelined ADCs like the HI5767 use multiple low-resolution stages to achieve high sample rates while keeping per-stage power dissipation modest, making them well suited for intermediate-frequency (IF) sampling, video digitisation, and instrumentation. Key features of the HI5767/4CAZ include 40 MSPS maximum sampling rate, 10-bit resolution, internal 2.5V bandgap voltage reference, single 5V analog supply, and CMOS/TTL-compatible digital outputs. The pipelined architecture with internal sample-and-hold delivers wide input bandwidth and low power consumption relative to flash converters of equivalent speed, and the SSOP-28 footprint allows compact PCB placement for multi-channel designs. Typical applications for the HI5767/4CAZ include digital oscilloscopes, IF-sampling communications receivers, CCD/CIS imaging signal chains, medical ultrasound front ends, and industrial inspection cameras. Designers choose this part when a small-footprint 10-bit, 40 MSPS ADC with internal reference and single-supply operation is needed. Designers should observe standard high-speed mixed-signal layout practice: decouple AVDD with 0.1uF and 10uF ceramics placed within 5 mm of the supply pin, keep analog and digital ground planes separate and join them at a single point near the ADC, and drive the analog input through an AC-coupling network or low-impedance buffer to preserve SFDR. The internal reference eliminates external reference noise pick-up but constrains absolute accuracy to about +/-25 mV initial tolerance.

HI5767/4CB-T

HI5767/4CB-T - 10-Bit 40MSPS Pipelined ADC | Renesas | 28-SOIC

The Renesas HI5767/4CB-T is a monolithic 10-bit pipelined analog-to-digital converter (ADC) with 40 MSPS sampling rate, integrated voltage reference, and TTL-compatible digital outputs, housed in a 28-pin SOIC (Wide) package on tape-and-reel. Designed in CMOS, the part supports the HI5767 family of 20/40/60 MSPS pin-compatible variants with 1 channel input and parallel output, targeting wideband, low-power signal acquisition. An ADC (analog-to-digital converter) is a data-converter integrated circuit that samples a continuous analog waveform and quantizes each sample to a binary code word; the ADC is a member of the data-converter IC family, which sits inside the broader power-management and signal-chain semiconductor taxonomy. Pipelined ADCs specifically use a multi-stage switched-capacitor architecture with per-stage flash sub-converters to achieve sample rates from a few MSPS to >100 MSPS while maintaining 8-14 bit resolution and small die area. Key features include an internal 2.5 V bandgap voltage reference, a single +5 V analog supply operation, and low-power CMOS design. The /4 speed-grade selects the 40 MSPS tier within the HI5767 family (the same die supports 20/40/60 MSPS via speed-grade ordering). TTL/CMOS-compatible outputs ease interface to FPGAs, ASICs, and microcontrollers without level translators. The pipelined architecture delivers consistent dynamic performance across the full Nyquist band; the CMOS process keeps typical power consumption low enough for multi-channel instrumentation boards and portable imaging designs. Internal reference trimming reduces external component count, simplifying BOM and improving accuracy. Typical applications include digital video processing, medical imaging front-ends, communications base-band signal capture, and IF/RF downconversion sampling. The wide 28-SOIC footprint supports both hand-prototype and high-volume assembly lines. Engineers choose this part when 10-bit dynamic range at 40 MSPS is sufficient and the integrated reference cuts BOM. When laying out the PCB, keep analog input traces short and symmetric to preserve SNR, and place the internal reference decoupling capacitor as close as possible to the supply pin.
