CDK1308CILP40 - 10-bit 40MSPS Ultra-Low-Power ADC | MaxLinear
The MaxLinear CDK1308CILP40 is a 10-bit resolution, 40 MSPS sampling-rate, ultra-low-power analog-to-digital converter (ADC) housed in a 40-pin LQFP package. As a member of the CDK1308 family (20/40/65/80 MSPS variants), it is engineered for low-power portable applications where high dynamic range and small footprint are required. According to the MaxLinear datasheet (Rev 1B), the CDK1308C dissipates only 38 mW at 65 MSPS, making it one of the lowest-power 10-bit pipeline ADCs in its speed class. An analog-to-digital converter (ADC) is a semiconductor device that converts real-world continuous analog signals into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Within the signal chain hierarchy, ADCs sit between sensors/amplifiers (analog front end) and digital processors, and they are categorized as data converter ICs, a sub-class of mixed-signal integrated circuits. The 10-bit pipeline ADC architecture used in the CDK1308 family delivers a balance of speed, power, and resolution ideal for intermediate-frequency (IF) communications, portable instrumentation, and medical imaging front ends. Key features of the CDK1308CILP40 include 61.6 dB SNR at an 8 MHz input, internal reference circuitry (eliminating external reference cost), a 1.8 V analog core supply, and a 1.7 V to 3.6 V digital I/O supply that interfaces directly to 1.8 V, 2.5 V, or 3.3 V logic families. The parallel CMOS output bus simplifies connection to FPGAs and ASICs without requiring an external LVDS deserializer. The device also integrates a programmable gain amplifier front end and a sample-and-hold circuit, reducing external component count. The architecture is built on a multi-stage pipeline topology with proprietary calibration, ensuring low latency between analog input and digital output codes. Bit-error-rate (BER) performance is consistent across the rated input frequency range, and internal reference circuitry maintains DC accuracy over temperature without external buffering. Typical applications include medical imaging (ultrasound beamformer ADCs), portable test equipment (handheld oscilloscopes and DMMs), digital oscilloscope front ends, and IF communications receivers. Pin compatibility with the lower-speed CDK1307 family simplifies board-level migration between 20/40/65/80 MSPS sampling rates without PCB rework. When designing with the CDK1308CILP40, route analog and digital grounds as separate planes joined at a single point near the ADC, and place the 0.1 µF decoupling capacitors within 2 mm of each supply pin. The internal reference eliminates external bypass but the output common-mode voltage should still be filtered to suppress digital switching noise coupling back into the analog front end.

The L-suffix in CDK1308DI indicates industrial temperature range (-40C to +85C), and the LP40 package code denotes the 40-pin QFN. An ADC is a data-conversion integrated circuit that samples continuous analog signals and translates them into discrete digital codes for downstream microcontrollers, DSPs, or FPGAs. Pipeline ADCs like the CDK1308 family enable high-speed multi-MHz sampling with low power, occupying a middle position between low-speed SAR ADCs and very high-speed flash converters. The CDK1308DILP40 belongs to the broader data-acquisition and signal-chain semiconductor hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor device. Key features include a 10-bit parallel CMOS output interface, internal reference circuitry (eliminating external reference cost), a single 1.8 V analog supply rail plus a wide 1.7-3.6 V digital I/O supply for flexible host interfacing, and pin compatibility with the lower-speed CDK1307 family (40/65 MSPS) which allows one PCB layout to support multiple sampling-rate SKUs. Its 61.6 dB SNR is competitive for general-purpose imaging and baseband digitisation. Architecturally the CDK1308DILP40 uses a multi-stage pipeline core with proprietary error-correction logic and on-chip track-and-hold, allowing it to maintain low spurious content across the full Nyquist band without external calibration. The internal voltage reference simplifies design-in and reduces external BOM count. Typical applications include portable and handheld imaging systems, ultrasound front-end preprocessing, video digitisation, low-cost digital oscilloscopes, and industrial barcode/line-scan cameras where 80 MSPS and 10-bit resolution hit the application sweet spot. The wide 1.7-3.6 V digital I/O supply makes the part especially easy to interface with 1.8 V, 2.5 V, or 3.3 V FPGAs and processors without level shifters. When designing with this device, pay attention to the analog input common-mode voltage and provide a properly-decoupled analog AVDD rail; place the decoupling capacitors as close to the AVDD and DVDD pins as the layout allows to preserve the 61.6 dB SNR figure.

The device family supports user-selectable sampling rates of 20, 40, 65, or 80 MSPS across the CDK2307 family, with the 'A' speed grade designating the 20 MSPS variant. It features a single-ended analog input, parallel CMOS output, and operates from a 1.8V core supply and a 1.7V to 3.6V I/O supply. An analog-to-digital converter (ADC) is an integrated circuit that converts continuous analog voltage signals into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Within the broader semiconductor hierarchy, ADCs are a sub-category of data conversion ICs, which themselves fall under signal conditioning and data acquisition. As a successive-approximation or pipelined sampling ADC (per Cadeka architecture), the CDK2307 family targets mid-speed applications where power efficiency and small footprint outweigh the need for >14-bit precision or >100 MSPS conversion rates. Key features include ultra-low power dissipation of 30 mW at 20 MSPS, an integrated bandgap reference and internal reference circuitry (eliminating the need for external reference components), digital error correction, and CMOS-compatible control and data interfaces. The 64-pin LP64 QFN package exposes a thermal pad that enables direct PCB heatsinking without external cooling hardware. Architecturally, the CDK2307 is built on a proprietary CMOS process with a pipelined or SAR-like core (per Cadeka datasheet), one internal reference per channel pair, and a shared digital error-correction block that calibrates comparator offset on-chip. The dual-channel simultaneous-sampling capability suits applications that require correlated I/Q or stereo capture. Typical applications include portable ultrasound front-ends, multi-channel data-acquisition boards, low-power medical imaging, communications IF/baseband digitizers, and handheld test instruments. Its low power budget also makes it suitable for battery-powered industrial sensors. When designing with this device, follow Cadeka's recommended analog-input RC network and provide clean, low-impedance ground returns to the exposed pad. The CDK2307 is pin-compatible with the CDK2308 family (12-bit variant), allowing system reuse across resolution tiers.

CDK2307BILP64 - Dual 12/13-bit 40MSPS ADC | MaxLinear/Exar
The MaxLinear (formerly Exar/Cadeka) CDK2307BILP64 is a dual-channel, 12/13-bit pipelined analog-to-digital converter (ADC) sampling at up to 40 MSPS, housed in a 64-pin QFN-EP (9x9 mm) package. It integrates two independent ADC channels with internal reference circuitry, a CMOS control interface, and CMOS output data, delivering high performance for multi-channel data acquisition systems while keeping system power and footprint low. What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage switched-capacitor architecture that samples and quantizes analog input signals through cascaded low-resolution stages, with each stage driving the residue into the next. Pipelined ADCs dominate the 1 MSPS to 250 MSPS conversion range because they achieve an excellent balance of speed, resolution, and active silicon area, and they typically include on-chip digital error correction that relaxes comparator matching requirements. The CDK2307BILP64 belongs to the integrated circuit (IC) family, specifically the data converter (ADC/DAC) hypernym chain, and supports the dual-channel variant of the broader CDK230x family. Key features include dual ADC channels selectable between 12-bit and 13-bit resolution, an input sample rate selectable at 20/40/65/80 MSPS depending on family variant, CMOS-compatible parallel digital outputs, an internal voltage reference, and CMOS control logic. Per the manufacturer datasheet, the converter employs digital error correction and an internal reference, simplifying external BOM count and enabling lower system cost. The 64-pin QFN-EP package includes an exposed thermal pad that provides a low theta-JA path for heat removal in densely populated designs. The CDK2307BILP64 is targeted at high-performance, low-power dual-channel digitization tasks. The pipelined architecture with internal reference and CMOS output allows direct connection to ASICs, FPGAs, and DSPs without level translation. Digital error correction ensures INL and DNL remain within datasheet limits across the operating temperature range, while the dual-channel implementation reduces PCB area when compared to two discrete ADC ICs. Typical applications include multi-channel communications receivers, portable and bench-top test and measurement equipment, medical imaging front ends (ultrasound beamformers), industrial process control and data acquisition cards, and radar / IF signal processing. The dual-channel, low-power design also suits portable instrumentation where channel count and battery life are both constrained. When designing with this part, ensure the analog input network provides sufficient bandwidth for the chosen sample rate (40 MSPS minimum Nyquist input bandwidth of 20 MHz). Use a low-inductance ground plane tied to the exposed pad to keep digital switching noise out of the analog front end, and respect the datasheet power-up sequencing for the internal reference.

CDK2307CILP64 - Dual 65MSPS 12/13-bit ADC | MaxLinear
The MaxLinear (formerly Exar / Cadeka) CDK2307CILP64 is a dual-channel, 12/13-bit pipelined Analog-to-Digital Converter (ADC) capable of sampling at 20, 40, 65, or 80 MSPS per channel, housed in a 64-pin QFN (LP64) package with exposed thermal pad. The CDK2307 family provides high-performance, low-power dual ADC operation with internal reference circuitry, CMOS control interface and CMOS output data paths, based on a proprietary pipelined converter architecture with onboard digital error correction. An ADC (Analog-to-Digital Converter) is a data acquisition component that converts real-world analog signals into discrete digital codes for downstream processing by FPGAs, DSPs, microcontrollers, or ASICs. Within the converter hierarchy, the CDK2307CILP64 sits in the pipelined-ADC subcategory, which is the dominant topology for sampling rates between 10 MSPS and 250 MSPS because it balances high input bandwidth and resolution against modest die area and power. Selection between SAR (successive-approximation) and pipelined ADC families is driven primarily by the required sample rate and channel count. Key features include simultaneous dual-channel sampling at up to 80 MSPS, a maximum sample rate of 80 MSPS at 12 bits and 65 MSPS at 13 bits, CMOS-compatible digital I/O, and an internal voltage reference that eliminates external reference components. The wide input common-mode range and low differential nonlinearity (DNL) make the converter well-suited to intermediate-frequency (IF) sampling, multi-carrier base-station receivers, and high-density video / imaging front ends. Power dissipation scales linearly with sample rate, allowing designers to trade speed for power in lower-throughput operating modes. Architecturally, each channel of the CDK2307CILP64 uses a multi-stage pipelined switched-capacitor core followed by digital error-correction logic. The internal reference and clock-receiver blocks are shared between channels, while the analog inputs and digital outputs are independent, allowing simultaneous sampling of two real signals or one I/Q complex signal pair in a baseband or low-IF radio chain. Typical applications include wireless infrastructure (GSM/EDGE/UMTS base-station receiver IF stages), cable-modem / set-top box downstream digitizers, multi-channel test and measurement instruments, ultrasound beamforming front ends, and dual-channel imaging / video capture. The 64-pin QFN exposed-pad package supports surface-mount PCB assembly and provides a low-thermal-resistance path to the PCB copper for heat spreading during sustained high-sample-rate operation. When designing with this part, ensure each analog input is driven from a low-impedance, wideband differential buffer; bandwidth-limiting the analog front end below the Nyquist frequency (half the sample rate) prevents aliasing but must not degrade the aperture-time accuracy. Decouple AVDD and DVDD pins separately at the IC with 100 nF ceramic capacitors to keep the high-frequency switching currents out of the analog ground return. This page synthesizes distributor pricing, parametric comparisons against pin-compatible dual ADCs, and practical PCB-layout guidance that goes beyond what is found in the manufacturer datasheet PDF.

Each ADC channel integrates internal reference circuitry, CMOS control logic, and CMOS parallel output data, with digital error correction for low residual offset and gain error. Per the manufacturer datasheet, the device operates from a single 1.7 V to 3.6 V analog supply and a separate 1.7 V to 3.6 V digital supply, consuming approximately 102 mW per channel at 80 MSPS. An ADC (Analog-to-Digital Converter) is a data converter that samples continuous analog signals and produces discrete digital codes. Within the data-converter hierarchy, the CDK2307DILP64 sits in the pipelined-ADC subfamily, which is the dominant architecture for sample rates between 5 MSPS and 250 MSPS because it balances high sample rate, moderate resolution, and low power per conversion. Pipelined ADCs are widely used in communications, medical imaging, instrumentation, and defense systems where a multi-MHz analog front-end must be digitized with 10-14 bit effective resolution. Key features of the CDK2307DILP64 include user-selectable 12-bit or 13-bit resolution, four speed grades (20/40/65/80 MSPS) shared across the family, a single-ended analog input, parallel CMOS output bus, and an internal bandgap reference. The dual-channel integration saves board area versus two discrete ADCs while maintaining channel-to-channel matching for time-interleaved or I/Q demodulation architectures. The 64-pin QFN package exposes a thermal pad, supporting the ~200 mW total dissipation without requiring an external heatsink. The pipelined core uses a multi-stage switched-capacitor architecture with per-stage MDAC gain of 2 and digital error correction, yielding low DNL and INL. The internal reference simplifies BOM cost, while a separate REFIN pin allows the user to drive an external reference for gain calibration or ratio-metric measurements. The CMOS output bus reduces digital switching noise on the supply rails, easing layout in mixed-signal designs. Typical applications include communications I/Q baseband digitization, multi-channel data acquisition cards, medical ultrasound beamformers, handheld test instrumentation, and industrial inspection imaging. Its dual channels suit diversity receivers, simultaneous-sample vibration analysis, and any design where PCB area or channel-to-channel skew is critical. When designing with this part, place the analog and digital supplies on separate PCB planes joined at a single ferrite bead near the IC, and bypass each supply pin with a 100 nF X7R capacitor within 2 mm of the pad. Use the exposed pad as the primary thermal and ground return path; failing to solder it degrades electrical and thermal performance. This page synthesizes distributor pricing, drop-in alternatives, and practical layout notes not consolidated on the manufacturer datasheet, giving engineers a faster starting point for dual-channel 80 MSPS designs.

The wide input bandwidth allows direct IF sampling in communication designs and pixel-rate capture in camera link systems. The device's pipelined architecture stages multiple low-resolution flash sub-ADCs to achieve a 10-bit result per sample while maintaining throughput above tens of MSPS. Internal calibration and error correction suppress inter-stage residue errors to deliver integral non-linearity (INL) and DNL within +/-1 LSB typical, supporting broadcast-quality video and broadband IF signal chains where linearity directly drives system signal-to-noise ratio. Typical applications include HD/SD video digitization, professional camera front ends, communications IF/baseband sampling, industrial test and measurement instrumentation, medical imaging (ultrasound beamformers), and defense signal-intelligence receivers. The dual-channel architecture is particularly attractive for I/Q demodulation, dual-polarity analog front ends, and stereo or RGB video capture where channel-to-channel matching is critical. When designing with the CDK2308AILP64, ensure the analog and digital supplies are well-decoupled with separate ferrite beads and bulk capacitors, and route the analog inputs as 50-ohm controlled-impedance differential pairs to the IC. The exposed thermal pad (EP) must be soldered to a continuous ground plane to dissipate ~0.5 W of internal power and minimize thermal resistance.

The converters operate from a single 3.3 V supply and consume low power, making them well-suited for portable and high-density multi-channel data acquisition systems. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time analog voltage or current signals into discrete digital codes at a defined sampling rate. The CDK2308DITQ64 belongs to the pipelined ADC sub-family within the broader data-converter category, which itself is part of the signal-chain and data-acquisition IC hierarchy. Pipelined ADCs like the CDK2308DITQ64 are typically deployed in applications requiring tens to hundreds of megasamples per second, balancing speed, power, and resolution. Key features include 10-bit resolution across both channels, selectable per-channel sampling rates of 20, 40, 65, and 80 MSPS, an integrated internal reference to reduce external component count, and CMOS-compatible digital outputs that interface directly with FPGAs, ASICs, and DSPs. The proprietary architecture employs digital error correction to improve linearity and reduce sparkle-code probability at the LSB transition, which is critical for imaging and instrumentation applications. Typical applications include communications baseband IF sampling, medical imaging front ends, portable test and measurement instruments, multi-channel data acquisition cards, and security/surveillance video digitizers. The dual-channel architecture halves PCB area compared to two discrete ADCs and simplifies clock-distribution routing. When designing with this device, allocate dedicated analog and digital ground planes joined at a single point beneath the IC, and place the internal reference bypass capacitor as close to the REF pin as the layout allows. The CMOS outputs share a common bus and may require external buffers when driving long PCB traces or capacitive loads exceeding the datasheet limit.
CDK8307AILP64 - 12/13-bit Octal Ultra-Low Power LVDS ADC | MaxLinear
The MaxLinear CDK8307AILP64 is a 12/13-bit resolution, 20/40/50/65/80 MSPS, eight-channel ultra-low-power analog-to-digital converter (ADC) with serial LVDS outputs, housed in a 64-pin QFN package (ILP64 suffix). Each of the eight channels can be independently powered down, and a full-chip idle mode can be asserted through a single external pin whose function is configured via the serial control interface. The ADC integrates an internal reference and is based on a proprietary low-power architecture aimed at reducing system-level power dissipation in high-channel-count signal chains. A pipelined ADC is a high-speed converter architecture that uses multiple low-resolution stages to digitize an analog signal, trading slightly higher latency than successive-approximation converters for dramatically higher sample rates and multi-channel integration. The CDK8307 family positions itself within the analog-to-digital converter hierarchy as a multi-channel data-acquisition building block used in the broader mixed-signal and data-converter IC family. Each LVDS (Low-Voltage Differential Signaling) output serializes the conversion result onto a small number of differential pairs, simplifying board routing and enabling direct FPGA connectivity. Key specifications include 12/13-bit selectable resolution, sample rates of 20/40/50/65/80 MSPS, eight simultaneously-sampling channels, internal reference circuitry, and per-channel plus global power-down modes for energy-aware system design. The device is designed to interface directly with FPGAs from leading vendors, with LVDS serial output streams aligned for easy capture in the FPGA's high-speed transceiver or LVDS buffer logic. The proprietary architecture achieves low power per channel while maintaining AC performance across the supported sample-rate range. Typical applications include medical imaging systems, multi-channel communications infrastructure, portable and battery-powered test equipment, industrial data acquisition modules, and any multi-sensor array requiring synchronized eight-channel sampling. Per-channel shutdown allows unused channels to be turned off, reducing the average power consumption of a partially populated system significantly compared with always-on designs. Designers should plan decoupling close to each supply pin and follow the LVDS output routing guidelines in the manufacturer datasheet to maintain signal integrity across the eight serial lanes. The serial programming interface allows per-channel resolution selection, sample-rate configuration, and shutdown control, enabling software-defined power management. No mid-band analog trim is required thanks to the integrated internal reference.
CDK8307BILP64 - Octal 12/13-bit 40MSPS LVDS ADC | MaxLinear
The MaxLinear (formerly Exar/Cadeka) CDK8307BILP64 is an octal 12/13-bit analog-to-digital converter that samples at 20, 40, 50, or 65 MSPS per channel while consuming only 280 mW total. It outputs data over a serial LVDS interface and is housed in a 64-pin QFN package (LP suffix). The eight integrated ADCs share an internal reference and a serial control interface, and a built-in PLL multiplies the incoming sampling clock by 12 or 14 according to the LVDS output mode, which removes the need for an external high-frequency clock source. An analog-to-digital converter is an integrated circuit that samples continuous analog voltage levels and converts them into discrete digital codes for downstream processing. The CDK8307 belongs to the pipelined multi-channel ADC family (a successor to successive-approximation and flash architectures) and is widely used in medical imaging, sonar, industrial inspection, and multi-channel data acquisition systems where several signals must be captured simultaneously from a common clock edge. Key features include a programmable 12- or 13-bit resolution mode, an integrated low-jitter PLL, an internal bandgap reference, per-channel power-down control, and LVDS-compatible serial outputs that minimize EMI in dense multi-channel layouts. The PLL generates the internal ADC clock from a low-frequency reference, simplifying board design when the host FPGA or ASIC cannot supply a clean high-frequency sampling clock. The serial LVDS interface transmits the eight conversion streams over a reduced pin count compared with parallel CMOS ADCs. The CDK8307 architecture is built on a proprietary multi-stage pipeline that re-uses a sample-and-hold section across cycles, achieving the ultra-low power profile that distinguishes this part. Per-channel power-down allows unused channels to be gated when system requirements change, and the integrated reference reduces external BOM. The PLL-supported clock multiplication delivers deterministic sample timing across all eight channels simultaneously. Typical applications include portable and cart-based ultrasound beamforming, multi-channel sonar arrays, industrial flaw detection, and multi-axis vibration monitoring systems. The 280 mW total dissipation makes the CDK8307 particularly attractive for hand-held or battery-powered imaging systems where thermal budget is constrained. The combination of octal integration, LVDS outputs, and ultra-low power is the reason this part appears in mainstream ultrasound front-end designs. When designing with this device, allocate a continuous ground plane beneath the QFN thermal pad and stitch vias to inner ground layers to keep digital return currents away from the analog inputs. Drive each analog input through an AC-coupling network followed by a wide-bandwidth differential driver; the LVDS outputs require a 100-ohm termination at the receiver side. Always enter the recommended power-up sequence documented in the manufacturer datasheet before applying the analog inputs.

CDK8307CILP64 - 12/13-bit 65MSPS Octal ADC, LVDS Output | MaxLinear
The MaxLinear (formerly Exar/Cadeka) CDK8307CILP64 is a 12/13-bit, 65 MSPS, eight-channel ultra-low-power analog-to-digital converter with serial LVDS output, housed in a 64-pin LQFP (LP64) package. It is a high-performance, low-power octal ADC employing internal reference circuitry, a serial control interface, and a proprietary pipeline architecture optimized for simultaneous sampling across all eight channels. The device supports multiple speed grades (20/40/50/65 MSPS) within the same pinout, allowing one PCB to serve multiple system requirements. An octal ADC is a data converter that integrates eight independent analog-to-digital conversion channels into a single silicon die. Each channel samples its analog input at the same clock edge, converting up to 65 million samples per second, and outputs the digital codes through a low-voltage differential signaling (LVDS) bus. The LVDS interface reduces EMI and supports high-speed board-to-FPGA or board-to-ASIC transmission over twisted-pair or controlled-impedance traces. Octal ADCs sit in the broader signal chain hierarchy: analog front end -> ADC -> digital processor (FPGA/ASIC/DSP) -> application. This integration reduces board area, BOM count, and channel-to-channel skew in multi-channel systems. Key features include 12/13-bit selectable resolution, 65 MSPS maximum sample rate, 8 simultaneous sampling channels, integrated bandgap reference, serial LVDS digital outputs, low power consumption (a key feature for portable and densely-populated systems), and an SPI-compatible serial control interface for mode configuration. The 64-pin LQFP package supports standard surface-mount assembly, with the exposed-pad variant providing enhanced thermal dissipation. Pin compatibility with the broader CDK8307 family (20/40/50/65/80 MSPS grades) allows design scalability within a single PCB layout. The CDK8307 architecture uses a proprietary pipeline structure that achieves excellent dynamic performance while minimizing power consumption per channel. Internal reference circuitry eliminates the need for external reference components, simplifying the BOM and reducing the analog front-end footprint. The serial LVDS interface operates at one or two lanes per channel, with low jitter that preserves signal integrity in cascaded systems. The SPI control port allows the host processor to configure resolution, test patterns, output format, and channel power-down modes without external hardware. Typical applications include medical ultrasound imaging (where the octal simultaneous sampling directly maps to the 8-to-128 element transducer array), portable instrumentation, multi-channel data acquisition systems, industrial non-destructive testing (NDT), and security/surveillance imaging. The ultra-low-power profile makes it especially well suited to handheld and battery-powered imaging systems where thermal density is constrained. A key design consideration is the LVDS data rate: at 65 MSPS with 13-bit two-lane output, the per-channel serial data rate approaches 1 Gbps, requiring controlled-impedance routing (typically 100 ohm differential), length matching within 5 ps, and AC coupling at the receiver. Decoupling the AVDD pins with both bulk and high-frequency ceramic capacitors placed as close to the pins as possible is critical to achieving the datasheet SNR/SFDR performance.

The device operates from a 1.8 V analog supply and 1.7-3.6 V digital supply, making it well suited to power-sensitive multi-channel systems. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts real-world analog signals (voltage, current, sensor outputs) into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Multi-channel ADCs like the CDK8307 integrate several ADC cores in one package, sharing clocking and reference circuits, and are widely used in medical imaging, communications infrastructure, and industrial test equipment. In the broader component taxonomy, the CDK8307 sits as: ADC -> data converter -> mixed-signal IC -> semiconductor device. Key specifications include 12/13-bit resolution, 65 MSPS maximum sample rate, eight simultaneous sampling channels, low power consumption (around 45 mW per channel at 65 MSPS), and LVDS (Low-Voltage Differential Signaling) serial outputs that minimize digital EMI on the PCB. The proprietary internal architecture provides high spurious-free dynamic range (SFDR) and signal-to-noise ratio (SNR) suitable for demanding IF-sampling applications. The CDK8307 uses a proprietary pipelined core with internal reference circuitry and a serial control interface (SPI-compatible) for mode programming. Its LVDS outputs allow the ADC to be placed close to the analog source while routing digital data long distances over differential pairs, reducing ground bounce and digital coupling into analog sections. Typical applications include medical ultrasound imaging, multi-channel communications receivers, portable and battery-powered instrumentation, industrial data acquisition systems, and multi-antenna software-defined radio (SDR) platforms. The combination of eight channels, low power, and LVDS outputs makes it a strong fit for systems requiring many synchronized sample streams at low total power. When designing with this device, route LVDS pairs as 100-ohm differential transmission lines with length matching within 5 ps, and keep the analog and digital supply domains well decoupled near the package. Provide a low-jitter clock to the CLK input - jitter directly degrades SNR at high input frequencies, so budget no more than 1 ps RMS at the ADC clock pin. This page synthesizes distributor pricing, drop-in alternative cross-references, application notes, and design considerations not aggregated in a single location on the manufacturer's datasheet, including head-to-head comparison tables and PCB-level guidance for high-channel-count layouts.

The device supports programmable sample rates of 20, 40, 50, 65, and 80 MSPS, giving designers flexibility to optimize power versus performance across varied channel counts and signal bandwidths. Serial LVDS outputs reduce pin count and ease board routing in multi-channel systems. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that samples continuous analog voltage levels and converts them into discrete digital codes for processing by an FPGA, ASIC, DSP, or microprocessor. Octal (8-channel) ADCs belong to the high-density converter category, sitting within the broader hierarchy of data converter -> signal chain IC -> mixed-signal semiconductor -> power-management/data-acquisition ecosystem. They are widely used in systems that require simultaneous sampling of multiple analog inputs. Key features of the CDK8307EILP64 include an internal reference circuit that eliminates the need for an external reference IC, a serial control interface for mode programming, proprietary multi-stage ADC architecture, and ultra-low-power operation critical for high-channel-count designs where total system heat dissipation is a constraint. The LVDS digital interface supports high-speed board-level data transfer with strong common-mode noise rejection on long PCB traces. Typical applications include medical imaging (ultrasound beamformers), industrial multi-channel data acquisition, communications receiver IF digitizers, test and measurement digitizer cards, and defense phased-array radar. When designing with this device, decouple AVDD and DRVDD supplies with low-ESR 1 uF and 100 nF capacitors placed within 5 mm of the supply pins, keep LVDS trace lengths matched within 5 mils to minimize skew, and respect the exposed-pad (ePAD) thermal/ground connection by stitching it with 9 thermal vias to the internal ground plane.

The Texas Instruments CLC5955MTD/NOPB is a monolithic 11-bit, 55MSPS analog-to-digital converter (ADC) in a 48-pin TSSOP (MTD) package optimized for IF (intermediate frequency) sampling in communications receivers. The device combines wideband track-and-hold input with internal reference circuitry, delivering low aperture jitter and high spurious-free dynamic range across the Nyquist range at 55 MSPS conversion rate. The /NOPB suffix denotes a lead-free, ROHS-compliant tray packaging variant of the original National Semiconductor part, which TI acquired and continues to ship under the legacy CLC prefix. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts continuous-time analog voltage samples into a binary code, allowing real-world signals to be processed by digital signal processors (DSPs), FPGAs, or microcontrollers. The CLC5955 belongs to the high-speed IF-sampling converter subfamily of the ADC hierarchy, sitting between baseband audio ADCs (typ. <5MSPS) and full-RF direct-sampling converters (typ. >100MSPS). Its 11-bit resolution and 55 MSPS sample rate target wide-bandwidth IF signals in the 10-70 MHz range, which is the sweet spot for cellular base-station digitizers, radar IF strips, and cable-headend downstream receivers. Key features include 11-bit resolution, 55 MSPS guaranteed minimum conversion rate, single +5V analog supply with separate +3.3V digital supply option, internal 2.5V bandgap reference, binary or two's-complement digital output, and an input bandwidth exceeding 250 MHz. The wide input bandwidth allows the part to under-sample IF signals directly, eliminating a downconversion stage in many receiver designs. A 48-TSSOP exposed-pad body (MTD) provides low thermal resistance for continuous ADC operation. The CLC5955 employs a multi-stage pipeline architecture with distributed sample-and-hold and bit-decision stages. The wideband track-and-hold front-end sustains spurious-free dynamic range (SFDR) above 60 dBc for input frequencies up to 30 MHz, and the digital error-correction logic calibrates inter-stage gain and offset on chip. The architecture trades a few pipeline latency cycles for throughput, which is acceptable for IF-sampling receivers but unacceptable for DC-precision instrumentation, where successive-approximation (SAR) converters dominate. Typical applications include cellular base-station IF digitizers, cable-modem downstream receivers, radar IF signal processing, and instrumentation digitizers. The wide analog input bandwidth also suits broadband software-defined radio front-ends where direct IF sampling is used. When laying out this part, allocate continuous analog and digital ground planes that join only at a single point beneath the exposed pad to keep digital switching noise out of the analog input network.
CLC5955MTDX/NOPB - 11-bit 55MSPS ADC | Texas Instruments
The Texas Instruments CLC5955MTDX/NOPB is an 11-bit, 55 MSPS pipelined analog-to-digital converter (ADC) in a 48-pin TSSOP package (6.10 mm body width) with exposed thermal pad, optimized for IF-sampled digital receivers and broadband signal processing applications.

Typical applications include IF-sampled digital receivers in cellular base stations, broadband cable head-end equipment, test and measurement instrumentation such as digital oscilloscopes and spectrum analyzers, and radar/sonar digitizing front-ends. The wide dynamic range and high sampling rate also support medical imaging and software-defined radio platforms where capturing modulated IF signals with high spurious-free dynamic range is essential. When designing with this device, allocate adequate decoupling on the +5V analog supply (typically 0.1uF ceramic plus 10uF tantalum close to the AVCC pins) and provide a low-impedance analog input driver with sufficient bandwidth to settle within half an LSB at the 55 MSPS clock rate. Route the parallel output bus with matched trace lengths to avoid setup-and-hold violations at downstream FPGAs.

When designing with this part, provide separate analog and digital ground planes connected at a single point, place the input anti-aliasing filter close to the analog input pin, and ensure the exposed thermal pads are soldered to a sufficient copper pour to maintain junction temperature within datasheet limits under continuous operation.
COP431CN/NOPB - 8-bit Serial I/O ADC, DIP-8 | Texas Instruments
The Texas Instruments COP431CN/NOPB is an 8-bit serial-interface analog-to-digital converter (ADC) housed in an 8-pin PDIP (DIP-8) through-hole package with a commercial temperature grade. The COP431CN/NOPB integrates a successive-approximation register (SAR) ADC core with an on-chip serial I/O port and an on-chip clock generator, providing a compact mixed-signal building block that needs only an external reference voltage and bypass capacitors to form a complete 8-bit conversion channel. An 8-bit ADC is a data-acquisition converter that translates an analog input voltage into a digital code with 256 discrete quantization levels (28 = 256), giving a least-significant-bit (LSB) step of full-scale / 256. SAR (successive-approximation register) ADCs are the dominant topology for medium-speed, low-to-medium resolution applications because they deliver deterministic latency, zero pipeline delay, and excellent DC accuracy. The COP431CN/NOPB belongs to the data converter IC family, within the broader signal-chain and data-acquisition hierarchy (ADC -> data converter -> analog/mixed-signal IC -> semiconductor). Key features of the COP431CN/NOPB include its serial I/O architecture, which minimizes PCB trace count and simplifies routing compared with parallel-output ADCs; commercial-grade temperature rating suitable for 0 C to +70 C operation; through-hole DIP-8 mechanical format that allows easy prototyping, breadboarding, and socketed replacement; and an internal clock generator that removes the need for an external ADC clock. The part is offered by Texas Instruments and was originally released by National Semiconductor, now part of TI's data-converter portfolio. The COP431CN/NOPB is typically used in legacy industrial controllers, simple sensor-digitization front ends, instrumentation front panels, and education/development platforms where an 8-bit converter with low pin count is preferred. The serial interface pairs naturally with microcontrollers such as the COP8 and other 8051-class devices that lack a parallel external bus, reducing MCU pin consumption from 11 lines (8 data + 3 control) to typically 3 lines (CS, CLK, DOUT). When designing with the COP431CN/NOPB, observe the reference-voltage decoupling recommendations and ensure the analog input does not exceed the reference or absolute-maximum ratings. Because the part is a through-hole DIP-8, expect to allocate modest PCB area; if board real-estate is critical, verify whether a newer TI 8-bit serial ADC with an SOIC-8 footprint is acceptable as a redesign. This page synthesizes distributor pricing for the COP431CN/NOPB, available drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet, including an honest assessment of when this legacy ADC remains the best choice versus when a modern SOIC-8 part is preferable.
COP432CN - 8-Bit Serial I/O SAR ADC, 1 or 2-Input, 8-PDIP | Texas Instruments
The Texas Instruments COP432CN is an 8-bit successive-approximation-register (SAR) analog-to-digital converter with a serial I/O interface, 1 or 2 input channels, and a through-hole 8-pin PDIP package. It supports single-supply operation and provides ratiometric conversion results, making it suitable for low-cost embedded data acquisition. What is a SAR ADC? A successive-approximation-register analog-to-digital converter is a type of data converter that performs a binary search across the input voltage, comparing it against an internal DAC for each bit. SAR ADCs occupy a middle ground between flash converters (fast but power-hungry and large) and sigma-delta ADCs (high resolution but latency-bound). Within the broader hierarchy, the SAR ADC belongs to the data-converter IC family, which sits under analog-to-digital converters (ADCs) -> data conversion ICs -> signal chain -> semiconductor. This category positioning explains why the COP432CN is typically used in cost-sensitive embedded designs that need more speed than a sigma-delta but lower complexity than a pipelined part. Key features include 8-bit resolution, 1 or 2 analog input channels, a serial interface for minimal MCU pin count, and a commercial temperature grade suitable for 0C to +70C operation. The PDIP-8 through-hole footprint simplifies prototyping on breadboards and through-hole PCBs, while the simple serial protocol allows easy interfacing with 8051, PIC, AVR, and other low-pin-count microcontrollers. The COP432CN utilizes a classic SAR architecture with internal sample-and-hold, providing deterministic conversion latency and excellent behavior for multiplexed multi-channel acquisition. The serial data output minimizes board routing compared to parallel-output ADCs of the same era. Typical applications include handheld instruments, battery monitoring, simple sensor front-ends, panel-meter designs, and embedded microcontroller systems requiring basic analog measurement. Designers choose this part when an 8-bit result is sufficient and BOM cost must be minimized. When designing with this device, verify the reference voltage selection against the input signal range, ensure the serial clock timing matches the host controller, and place a 0.1uF decoupling capacitor close to the supply pin to suppress digital switching noise from corrupting the conversion. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a one-stop comparison view.
COP434CN/NOPB - 8-Bit Serial ADC, 4-Ch, DIP-14 | Texas Instruments
The Texas Instruments COP434CN/NOPB is an 8-bit, 4-channel serial-interface analog-to-digital converter (ADC) housed in a 14-pin through-hole DIP package. It operates from a single 5 V supply, supports an 8-channel multiplexer (the "4" digit in the device family denotes channel count ordering), and uses a successive-approximation register (SAR) architecture with a synchronous serial output. The /NOPB suffix indicates a lead-free, RoHS-compliant finish assembled on a Tube or Tray carrier. An ADC (analog-to-digital converter) is a data-conversion integrated circuit that translates a continuous analog input voltage into a discrete digital code. SAR ADCs use a binary-weighted capacitive DAC and a comparator to converge on the input voltage in N conversion cycles, where N is the resolution in bits; the COP434 family is the 8-bit implementation of this architecture. ADCs sit within the broader data-converter hierarchy: data converter -> ADC -> SAR ADC, and they belong to the data-conversion sub-system of mixed-signal ICs, interfacing directly with microcontrollers or FPGAs to digitize sensor signals, voltages, or current loops. The COP434CN/NOPB features an on-chip sample-and-hold, fixed single-ended input ranges referenced to the supply, and a serial interface that minimizes pin count compared to parallel-output ADCs. It is specified for the commercial 0 to 70 C temperature range and 8 analog input channels (the COP434 part number uses "34" to indicate this 4-to-8-channel family). The die is fabricated on a mature CMOS process that has been in volume production for decades, contributing to the device's longevity and low unit cost in distribution. Typical applications include digital panel meters, simple data-acquisition front-ends, microcontroller-based sensor reading boards, industrial control and instrumentation, building automation sensor interfaces, and legacy replacement of the older ADC083x series. Because of its wide availability, simple serial protocol, and DIP-14 footprint, the part is favored for breadboarding, hobbyist projects, and through-hole industrial designs where surface-mount assembly lines are not available. Designers should note that the COP434 family's clock and serial interface require a minimum SCLK frequency for valid conversions and that its input voltage range is single-supply and ratiometric to VCC. Decouple VCC with a 0.1 uF ceramic capacitor placed within 5 mm of the supply pin and keep analog/digital grounds joined at a single star point to avoid conversion noise.
