AD9028JZ - 8-Bit 300 MSPS Flash ADC | Analog Devices
MPN: AD9028JZ ✗ Akhir HidupAD9028JZ Ringkasan
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.

Aplikasi Umum
AD9028JZ cocok untuk 6 aplikasis: Digital Oscilloscope Acquisition, High-Speed Pulse Analysis, Laboratory Signal Instrumentation, Industrial Control Signal Monitoring, Communications Test Equipment, FPGA Real-Time Signal Processing.
Digital Oscilloscope Acquisition
The AD9028JZ fits a high-speed parallel acquisition channel because it converts at 300 MSPS and provides 8-bit digital samples without a serial-output stage. A capture system can route the parallel data into FPGA logic or a high-speed memory interface. The 300 MSPS sampling rate supports short time intervals between samples, while 8-bit resolution limits amplitude granularity. Before implementation, confirm the input range, analog bandwidth, acquisition settling, clock requirements, and output timing in the official datasheet, because those values are not established by the supplied distributor excerpts.
High-Speed Pulse Analysis
The AD9028JZ is applicable to pulse and transient analysis systems that need rapid digitization rather than a high-resolution serial ADC. Its 300 MSPS conversion rate can capture changing waveforms, and the parallel interface can reduce the serialization burden on downstream FPGA logic. The single-ended input and negative analog supply must be accommodated by the front end. Engineers should verify input bandwidth, full-scale range, clock-jitter tolerance, and output delay before setting the capture bandwidth; none of these values is available in the verified search snippets.
Laboratory Signal Instrumentation
For laboratory signal instrumentation, the AD9028JZ offers a compact 8-bit sampling path at 300 MSPS that can feed real-time analysis logic. The device can form part of an oscilloscope, waveform monitor, or automated test system where the objective is rapid sampling and parallel digital transfer. Its commercial 0 °C to 70 °C rating suits controlled indoor environments. The application must include negative 5 V analog and digital rails, suitable input conditioning, and reference design review because the verified data does not specify input range, reference requirements, power dissipation, or dynamic accuracy.
Industrial Control Signal Monitoring
The AD9028JZ can be considered for fast feedback or monitoring functions in industrial control equipment where sampled data must be processed by parallel digital logic. Its 300 MSPS rate provides more temporal resolution than typical low-rate supervisory ADCs, while the 8-bit output supports straightforward digital processing. Commercial-temperature operation from 0 °C to 70 °C limits suitability to normally conditioned indoor environments. Before deployment, evaluate noise performance, input bandwidth, reference stability, isolation strategy, and failure behavior; those specifications require confirmation from the manufacturer datasheet.
Communications Test Equipment
The AD9028JZ may serve as a fast sampling element in communications test equipment that captures short-duration events and performs parallel-domain processing. A 300 MSPS flash ADC can support envelope, timing, or statistical analysis when the source bandwidth and required amplitude resolution are modest. The converter's single-ended input and negative analog and digital rails require careful interface design. For communications systems demanding greater dynamic range, differential drive, or lower distortion, engineers should compare the complete datasheet metrics before committing to this 8-bit device.
FPGA Real-Time Signal Processing
The AD9028JZ is suited to FPGA-based real-time signal processing because its parallel output avoids the throughput and latency burden of a high-speed serial link. The FPGA can capture, filter, decimate, or analyze samples after each 300 MSPS conversion. Practical implementation requires confirming output bit mapping, clock-edge relationships, data-valid timing, and logic compatibility from the official timing tables. The ceramic 68-terminal package also requires careful assembly planning, and the commercial 0 °C to 70 °C range should be checked against the enclosure's worst-case temperature.

Catatan Desain
Design the AD9028JZ around negative analog and digital rails in the verified -5.46 V to -4.94 V range. The exact sequence, tolerance, current consumption, and relationship between the analog and digital supplies must be confirmed in the official datasheet. Decouple each supply domain at the device pins and follow the manufacturer reference layout; the supplied distributor excerpts do not specify capacitor values, so they must not be guessed.
Treat the 68-terminal ceramic LCC-68 mechanical drawing as mandatory for layout. The verified listings identify a square QFP-style package code and ceramic construction but do not provide dimensions, terminal pitch, or a complete pin map. Do not create a land pattern from generic QFP libraries until the official package drawing and terminal numbering have been cross-checked.
Account for the converter's single-ended input and 300 MSPS operating rate when defining the analog front end. Use short, controlled-impedance paths and isolate the input from clock and digital return currents. Because the verified data omits input bandwidth, full-scale range, jitter tolerance, and settling behavior, obtain those values before selecting amplifier gain, filter bandwidth, or sampling clock components.
Informasi Konformitas
The verified product listings do not provide product-specific RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not applicable because no automotive qualification is identified for this commercial-grade converter.
