The Analog Devices AD871JD is a 12-bit, 5 MSPS monolithic analog-to-digital converter with an on-chip high-performance track-and-hold amplifier and voltage reference in a 20-lead plastic DIP package. The converter combines 5 million samples per second throughput with 0.17 LSB RMS input-referred noise, a guaranteed 0.5 LSB differential nonlinearity error, 68 dB signal-to-noise and distortion ratio, and 73 dB spurious-free dynamic range. An ADC is a data-acquisition IC that converts an analog voltage into a digital code. Within the data-conversion hierarchy, the AD871 belongs to the ADC and DAC class, uses a monolithic semiconductor implementation, and includes a sampling track-and-hold stage plus an on-chip voltage reference. This integration reduces the number of external precision components needed in instrumentation and signal-acquisition systems. The 12-bit resolution provides 4096 possible output-code levels, while the 5 MSPS conversion rate supports acquisition of rapidly changing waveforms. Its 0.17 LSB RMS input-referred noise supports low-noise measurements, and the specified 0.5 LSB maximum differential nonlinearity helps limit transfer-curve error. The 68 dB SNDR and 73 dB SFDR characterize dynamic performance when examining harmonic and distortion products in the sampled signal. The AD871 is a monolithic ADC rather than a multiplexed multichannel converter. Its integrated track-and-hold amplifier acquires the analog input before conversion, while the internal voltage reference provides the conversion reference without a separate reference IC. Digital output coding, input polarity, output logic levels, acquisition timing, and interface details should be confirmed from the manufacturer datasheet before layout or firmware is finalized. Typical uses include industrial process monitoring, laboratory data acquisition, waveform analysis, communications receivers, and embedded instrumentation. The 5 MSPS rate is useful when the sampled signal changes on a timescale of hundreds of nanoseconds, while 12-bit resolution balances measurement fidelity against converter cost and data-processing requirements. A key design consideration is analog-input conditioning. The source impedance, acquisition time, input voltage range, supply voltage, and reference behavior must be reviewed in the datasheet. PCB signal integrity and grounding are especially important because high-speed sampling can convert layout coupling or supply disturbance into codes and reduce effective SNR. This page consolidates the verified manufacturer-derived performance data, distributor pricing and availability, datasheet links, engineering application guidance, and explicitly documented data gaps. It also distinguishes verified AD871JD facts from unresolved package, pinout, lifecycle, and drop-in replacement details so engineers can make sourcing decisions without relying on unsupported assumptions.

For signal bandwidths below 10 MHz, the series input resistor may be increased proportionally; otherwise, it should not exceed 200 ohms. Typical uses include video and multimedia digitization, high-speed data acquisition, communications, imaging, portable instrumentation, and CCD-based input systems such as color scanners. The AD876's single-supply operation and low power are especially relevant to portable equipment, while its pipelined 20 MSPS conversion rate supports sampled signal chains operating at the upper end of its supported bandwidth. Designers should treat the analog input network as a matched high-speed signal path. Use the manufacturer-recommended input impedance and termination network, observe the stated series-resistor limit, and provide clean supply decoupling. Because the converter has 160 mW power dissipation, system-level thermal requirements remain modest, although total converter and digital-interface power should be included in enclosure temperature calculations.

AD9020KJ - 10-Bit 60 MSPS ADC | Analog Devices
The Analog Devices AD9020KJ is a 10-bit, 60 MSPS A/D converter with TTL-compatible outputs, a bipolar analog input, and a 56 dB signal-to-noise ratio at a 2.3 MHz input frequency. It is a monolithic sampling ADC identified by the KJ order code and supported by the Analog Devices AD9020 datasheet. The package and temperature details for this exact order code require confirmation from the current ordering guide. An ADC is an analog-to-digital converter, a data-acquisition IC that samples a continuous analog voltage and maps each sample to a digital code. The AD9020 belongs to the ADC and DAC hierarchy and targets instrumentation, communications, test and measurement, and professional video systems. Its 10-bit resolution provides 1,024 code levels, while its 60 MSPS sampling capability supports high-speed waveform capture when the complete signal chain meets the converter's timing and analog-input requirements. The verified manufacturer description identifies a 10-bit, 60 MSPS converter with TTL outputs and a bipolar analog input rated to 1.75 V. A listed feature value gives 56 dB SNR for a 2.3 MHz input, and a secondary data source reports low input capacitance of 45 pF. These characteristics make the device relevant where compact 10-bit conversion is preferred over higher-resolution but lower-speed converters. The datasheet also notes intermodulation testing at 2.3 MHz and 3.0 MHz input frequencies and power-supply sensitivity measurements, showing that dynamic and analog performance require careful test setup. The AD9020 uses a sample-and-hold input architecture and produces parallel digital output codes. Proper operation requires compliant analog drive, adequate source settling for the approximately 45 pF input capacitance, and interface timing that respects the converter's acquisition and output delay. Digital capture circuits should account for output skew and account for the required settling interval before sampling the 10-bit word. Exact logic thresholds and output timing must be taken from the manufacturer datasheet. Typical applications include digital oscilloscopes, medical imaging equipment, professional video systems, communications infrastructure, and industrial data-acquisition modules. For oscilloscopes and medical imaging, the AD9020 offers a useful balance of speed and 10-bit resolution, while professional video designs benefit from its 60 MSPS conversion rate. System designers should select external amplifiers and filters based on the analog input range and capacitance rather than assuming that an ADC can compensate for inadequate signal conditioning. When designing around the AD9020KJ, begin by confirming the package, pinout, grade, temperature range, and availability for the exact KJ suffix. Use the manufacturer's AD9020 data sheet and current ordering information rather than treating the base AD9020 name as complete orderable metadata. Keep high-speed analog traces short, provide a stable reference and supply arrangement, and verify interface timing with the assembled system. This page separates verified AD9020-family information from order-code details that were not present in the supplied records.
AD9022BZ - 12-Bit 20 MSPS Monolithic ADC | Analog Devices
Analog Devices AD9022BZ is a 12-bit, 20 MSPS monolithic analog-to-digital converter with an on-chip track-and-hold circuit and internal reference. The converter is available in a 28-terminal CDSO28 ceramic surface-mount package, supports bipolar analog input, and uses parallel word access with TTL-compatible logic. Its listed low power dissipation is 1.4 W, making it suitable for systems where conversion speed and integrated analog front-end functionality are more important than minimum energy per conversion. An ADC converts a continuously varying analog voltage into a digital code suitable for processing by digital logic, firmware, DSPs, or other computing systems. Within the broader semiconductor hierarchy, the AD9022BZ is an ADC, part of the data-converter IC family and the wider analog and mixed-signal semiconductor category. Monolithic construction places the sampling, conversion, reference, and associated functions on one integrated circuit, simplifying the analog signal chain compared with a discrete design. The principal performance specifications are 12-bit resolution, a 20 MSPS conversion rate, and 1.4 W power dissipation. The 12-bit code provides 4,096 digital output levels, while the 20 MSPS rating establishes the maximum stated conversion throughput. On-chip track-and-hold and reference functions reduce the number of external analog support components required. TTL-compatible logic provides a defined digital interface for systems operating with compatible voltage levels. The AD9022 uses proprietary conversion technology, as identified by distributor and datasheet records. It accepts a bipolar analog signal and presents parallel output data. This parallel architecture can simplify connection to suitable digital receivers, although the complete system must account for output timing, data acquisition, clocking, and input-conditioning requirements. The internal reference and track-and-hold circuitry provide a more complete conversion solution than a bare sampling ADC. Typical uses include radar receivers, digital communications equipment, and other high-speed signal-processing systems that need local conversion of an analog waveform. The 20 MSPS rate supports sampling of substantially faster signals than a general-purpose low-rate instrumentation ADC, while the 12-bit resolution provides a practical balance between code density, interface width, power, and implementation complexity. Parallel outputs are especially useful when samples must be transferred quickly without a serial-link overhead. A key design consideration is that the AD9022BZ consumes 1.4 W and requires careful thermal management. The datasheet also identifies a CDSO28 ceramic package with gull-wing terminals, so PCB footprint, assembly process, thermal paths, and soldering requirements must be checked against the manufacturer documentation. Input range, supply requirements, timing, output coding, and temperature limits are not stated in the supplied verified records and must be confirmed before design release. This page combines the verified distributor and datasheet data with practical engineering guidance, including sourcing context, application fit, comparison limitations, and design cautions. Because the supplied cross-reference search did not identify a verified pin-compatible replacement, no unsupported drop-in substitute is presented as an engineering choice.
AD9023AZ - 12-Bit 20 MSPS Parallel ADC | Analog Devices
The Analog Devices AD9023AZ is a 12-bit analog-to-digital converter capable of 20 MSPS, featuring parallel word access and 28 terminals for high-speed data acquisition. The available product information identifies a maximum linearity error of 0.0732% and an operating temperature range of -25°C to +85°C. It is designed for applications requiring rapid conversion of analog input signals into parallel digital data. An ADC is an analog-to-digital converter, a semiconductor that samples an analog voltage and converts it into a proportional digital code. ADCs sit at the boundary between sensors, amplifiers, and digital processing systems. The AD9023AZ belongs to the parallel-output ADC family, where each conversion produces a multi-bit value through a parallel interface rather than a serial data stream. This architecture can simplify connections to parallel FPGA, DSP, or data-capture circuitry when sufficient board routing space is available. The verified product information identifies three principal performance characteristics: 12-bit resolution, a maximum sampling rate of 20 MSPS, and a maximum linearity error of 0.0732%. The 12-bit format provides 4,096 discrete codes, while the 20 MSPS capability permits 20 million conversion results per second. These figures make the device relevant to waveform capture, communications, industrial monitoring, and other systems in which the sample rate and digital word width must be balanced against routing complexity. Parallel word access distinguishes the AD9023AZ from serial-interface converters. Parallel output can provide direct multi-bit transfer between the converter and receiving logic, although the 28-terminal package requires careful routing and signal-integrity control. Engineers should preserve the device's specified analog and digital supply requirements, reference arrangement, clocking method, and input settling conditions, but those detailed electrical parameters are not present in the supplied verified data and must be confirmed in the manufacturer datasheet before implementation. Typical application opportunities include digital oscilloscope and waveform-capture front ends, communications receivers, industrial process monitoring, medical instrumentation, and control systems. The 20 MSPS rate supports moderate-bandwidth digitization, while the 12-bit resolution offers a practical balance between conversion accuracy, interface width, storage requirements, and processor capacity. Applications requiring substantially higher rates, resolution, or serial data transfer should use a different converter architecture. A primary design consideration is the parallel-data routing burden. Traces carrying adjacent digital output bits should be length-matched where practical, clocks should be routed cleanly, and analog input circuitry should be isolated from switching and high-current digital paths. Power and decoupling recommendations must follow the official manufacturer documentation rather than values inferred from marketplace listings. This page consolidates the verified AD9023AZ resolution, sampling rate, linearity, temperature, inventory, and pricing information with application guidance and engineering considerations. It also identifies where datasheet confirmation is still required, avoiding unsupported claims about voltages, pin assignments, package dimensions, and drop-in replacements.
AD9023BQ - 12-Bit 20 MSPS ADC | Analog Devices
Analog Devices AD9023BQ is a 12-bit, 20 MSPS analog-to-digital converter designed for high-speed signal acquisition in a 28-pin ceramic dual in-line package (28-CDIP). It accepts a nominal analog input range of -1.024 V to 1.024 V and operates from a nominal 5 V supply with a maximum supply current of 240 mA. The device is identified by Analog Devices as the AD9023BQ product and is listed in the verified distributor data as an active-production component. An ADC is a data-converter IC that samples an analog voltage and converts it into a numerical value for processing, storage, or transmission. In the broader electronics hierarchy, an ADC belongs to data converters and interface ICs. The AD9023BQ combines a 12-bit quantization resolution with a 20 MSPS conversion rate, making it suitable for systems that require faster sampling than low-resolution sensor-interface converters while retaining more precision than comparators and simple threshold circuits. The principal verified specifications are 12-bit resolution, a 20 MHz sample rate, a -1.024 V to 1.024 V analog input range, a nominal 5 V supply, a maximum supply current of 240 mA, and a 28-CDIP package. These figures establish the part's basic acquisition bandwidth and input-scaling boundaries. Detailed dynamic performance, input impedance, reference requirements, noise figures, power consumption, and operating-temperature limits were not supplied by the verified sources and therefore require confirmation from the manufacturer datasheet before precision design. The AD9023BQ is suited to instrumentation, communications, industrial control, and embedded signal-processing systems where a parallel or otherwise documented digital ADC interface is required. At 20 MSPS, one sample is acquired every 50 ns. A downstream processor or FPGA must therefore handle the converter's output rate and associated clocking requirements. The nominal -1.024 V to 1.024 V input window can represent a centered, bipolar signal when the complete input network, reference, and digital calibration strategy are designed consistently. Application suitability depends on the source impedance, acquisition time, reference voltage, clock jitter, and required signal bandwidth. Designers should treat 20 MSPS as the sampling rate rather than automatically assuming that the full Nyquist bandwidth is usable; analog front-end filtering and datasheet timing limits determine the practical input bandwidth. The 240 mA maximum supply-current figure also makes 5 V rail capacity and thermal design relevant in compact or multi-channel systems. The 28-CDIP package is a through-hole ceramic package rather than a compact surface-mount land pattern. Board layout should preserve adequate clearance around the package, route high-speed digital outputs away from sensitive analog inputs, and provide stable supply and reference decoupling exactly as required by the manufacturer datasheet. Because the verified data does not provide a pinout or detailed application circuit, PCB designers should not assign pins or capacitor values from inference. This page consolidates the verified distributor specifications, current pricing indication, package information, and engineering-oriented acquisition guidance. It also distinguishes documented facts from missing data, avoiding invented pin assignments, dynamic-performance claims, or substitutes that cannot be proven pin-to-pin compatible with the AD9023BQ.
AD9028JZ - 8-Bit 300 MSPS Flash ADC | Analog Devices
The Analog Devices AD9028JZ is an 8-bit flash-method analog-to-digital converter with a 300 MSPS conversion rate, one single-ended input, and parallel output access in a 68-terminal ceramic LCC-68 package. According to the verified distributor data, its analog and digital operating-voltage ranges are -5.46 V to -4.94 V, while its commercial temperature grade covers 0 °C to 70 °C. A flash ADC is a parallel-comparison data converter that evaluates an analog input against multiple internal reference thresholds simultaneously. Within the ADC hierarchy, the AD9028JZ belongs to the flash-converter family, the ADC category, and the broader data-converter and semiconductor ecosystem. Its architecture provides direct conversion without the multistage pipeline commonly associated with higher-resolution converters, making it suitable for systems that require rapid sampling and digital parallel data rather than a low-resolution, very-high-rate serial interface. The verified listings identify 8-bit resolution, a 300 MSPS sampling rate, one single-ended analog input, parallel access, commercial temperature grade, and a 68-terminal ceramic package. These characteristics make the device relevant to high-speed instrumentation, pulse-processing systems, digital oscilloscope or signal-analysis front ends, and industrial control loops. The parallel interface also allows captured samples to be transferred directly into digital logic or parallel-processing hardware without a serial-output protocol. Operationally, the AD9028JZ requires negative analog and digital supply voltages. The verified operating ranges of -5.46 V to -4.94 V indicate that the circuit must accommodate a negative 5 V rail rather than conventional positive supply rails. Designers should treat power sequencing, bypass-capacitor placement, reference stability, clock distribution, and input-signal conditioning as system-level responsibilities. The supplied search data does not expose the complete clock, input-range, reference-voltage, power-consumption, or bit-timing tables, so those values must be confirmed in the manufacturer datasheet before a new design is released. Typical application candidates include digital oscilloscope acquisition channels, pulse and waveform analysis, high-speed closed-loop monitoring, communications test equipment, and embedded real-time signal processing. The 300 MSPS sampling rate is the principal selection criterion when individual samples must be captured at short intervals, while 8-bit resolution defines the digitization granularity. Applications requiring greater dynamic range, differential inputs, serial data transport, or automatic gain control need a different converter architecture rather than a direct assumption of equivalence. Because the AD9028JZ uses a legacy-style 68-terminal ceramic package, PCB planning requires the manufacturer package drawing and a complete pin map. The verified distributor snippets identify the package as ceramic LCC-68 and also describe a square QFP-style package code, but they do not provide a trustworthy pin-by-pin assignment. Engineers should not assign signals or power pins from package shape alone; verify every terminal against the Analog Devices datasheet and compare land patterns before layout release. This page consolidates the verified AD9028JZ specifications, pricing status, package information, source links, and engineering cautions into a design-focused product record. It also distinguishes documented facts from missing electrical details, helping engineers evaluate the 8-bit, 300 MSPS converter efficiently without mistaking unverified substitute or pinout information for manufacturer data.
AD9032BZ - 12-Bit 25.6 MSPS ADC | Analog Devices
Analog Devices AD9032BZ is a 12-bit analog-to-digital converter with a maximum conversion rate of 25.6 MSPS, onboard track-and-hold circuitry, voltage references, and timing circuits, housed in a single 40-pin hybrid package. The converter uses a subranging architecture and supports bipolar analog inputs across a 1.024 V input range. Its ECL-compatible interface, 74 dB spurious-free dynamic range to 12 MHz, and 3.8 W low-power specification make it suitable for high-speed signal acquisition. An ADC is an analog-to-digital converter, a mixed-signal semiconductor that samples a continuous analog voltage and converts it into a numeric code for processing, storage, or transmission. The AD9032 belongs to the data-converter IC hierarchy and combines a sampling track-and-hold stage, internal references, conversion timing, and a parallel output interface in one package. This integration reduces the number of external support components required in high-speed instrumentation. The AD9032BZ provides 12-bit resolution and conversion rates from DC to 25.6 MSPS. Its differential bipolar input spans -1.024 V to 1.024 V, while the device operates from a nominal 5 V supply. The converter also provides 74 dB spurious-free dynamic range to 12 MHz. These characteristics balance quantization performance against the throughput required for radar, communications, spectrum analysis, and medical instrumentation. Internally, the AD9032 uses a subranging converter architecture to achieve high conversion speed while retaining 12-bit output resolution. The onboard track-and-hold, references, and timing circuits support a compact, coordinated signal chain. The 40-pin hybrid package provides the analog, digital, reference, and clock connections needed for operation, while the ECL-compatible output interface supports high-speed digital capture systems. Typical applications include radar and signal-intelligence receivers, digital spectrum analyzers, communications receivers, medical diagnostic equipment, and instrumentation requiring 12-bit conversion at rates up to 25.6 MSPS. For these systems, the AD9032BZ can capture a wide input bandwidth and represent sampled voltages with 12-bit granularity. Its integrated timing and reference functions also reduce board-level implementation complexity. A primary design consideration is that the 3.8 W power rating requires attention to thermal management, supply integrity, and high-speed layout. Input and digital-return paths should be controlled to preserve the stated dynamic performance, while clocking and data-capture timing must be designed around the converter's operating rate. The manufacturer's product page and datasheet should be consulted for the complete pin arrangement, timing diagrams, and application recommendations. This product summary combines verified manufacturer specifications, distributor pricing, compatibility information, and practical selection guidance. It distinguishes confirmed drop-in options from generic cross-reference tools and highlights the thermal, signal-integrity, and clocking constraints engineers must evaluate when integrating this high-speed converter.
AD9038JE - Dual 14-Bit 65 MSPS ADC | Analog Devices
Analog Devices AD9038JE is a dual 14-bit, 65 MSPS low-power 3 V analog-to-digital converter offered in a 68-terminal square QCCN package. The verified product listings identify the device as a commercial-grade, no-lead package with 68 terminals, while the available distributor data describes it as a dual-channel converter intended for low-power 3 V designs. Together, these details position AD9038JE for communication, instrumentation, and signal-processing systems that require two synchronized high-speed conversion channels. An ADC is an analog-to-digital converter, a semiconductor in the ADC/DAC and data-converter hierarchy that samples an analog voltage and converts it into a digital code. A dual converter can process two analog inputs through two conversion channels, while its 14-bit resolution represents each sample with 16,384 discrete quantization levels. A 65 MSPS sampling rate allows each channel to acquire up to 65 million samples per second, making the device relevant to wideband signal acquisition, communications receivers, radar, test equipment, and precision industrial measurement. The AD9038JE is identified as a low-power 3 V ADC. These characteristics suit compact systems in which a dual converter can reduce component count and board area compared with two separate single-channel ADC packages. The 68-terminal QCCN package also provides a substantial lead count for analog, digital, reference, clock, and supply connections. Because the supplied search excerpts do not expose the complete electrical tables or pin assignment, engineers should verify input range, reference voltage, clock architecture, digital interface, power consumption, and output coding against the official manufacturer documentation before layout or firmware release. Typical implementations place the two ADC channels around a shared clock and data-capture system. Communications equipment can use the converters for intermediate-frequency or baseband sampling, while instrumentation systems can apply them to dual-axis or multichannel sensor signals. The converter may also support digital oscilloscope, spectrum-analysis, and industrial control equipment when its sampling architecture and timing requirements match the application. PCB design should treat analog inputs, reference connections, clocks, supplies, and digital outputs as separate domains. Keep input and reference traces short, route clock signals away from sensitive analog paths, provide local high-frequency bypass capacitance, and return digital currents through a deliberate ground path. Differential clock quality is particularly important because timing jitter can limit the effective noise performance of a high-speed converter even when nominal resolution is adequate. This page consolidates the verified distributor specifications, sourcing links, package information, and application guidance for AD9038JE. Detailed values absent from the supplied excerpts are explicitly identified rather than estimated, allowing engineers to distinguish confirmed product attributes from information that must be confirmed in the manufacturer datasheet before design-in.
