AD9023BQ - 12-Bit 20 MSPS ADC | Analog Devices
Артикул: AD9023BQ ✓ АктивенAD9023BQ Обзор
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.

High-Speed Data Acquisition
AD9023BQ suits laboratory and industrial acquisition systems that require sampled data at 20 MSPS with 12-bit numerical resolution. Its documented -1.024 V to 1.024 V input range provides a centered signal window for appropriately conditioned bipolar waveforms. The converter produces one 12-bit code every 50 ns at the maximum sampling rate, so the downstream FPGA or DSP must accept the documented output format and handle clocking without introducing excessive jitter. The 28-CDIP package favors instrument chassis and through-hole prototype boards rather than compact surface-mount systems. Because acquisition time, SNR, SFDR, and input impedance are not included in the verified data, the analog front end must be designed only after those manufacturer specifications are confirmed.
Рекомендуется
Communications Receiver
AD9023BQ can be evaluated for communications receiver front ends where a 12-bit, 20 MSPS converter is sufficient for the required signal fidelity and sampling plan. The documented bipolar input range allows a source network to map a centered waveform into the converter's -1.024 V to 1.024 V span. In an IF or baseband receiver, the sampling clock must meet the jitter and acquisition requirements stated in the manufacturer datasheet, while the analog filter should limit out-of-band energy before the converter. The verified information does not quantify dynamic range or spurious performance, so suitability for a specific modulation standard cannot be concluded from the 12-bit and 20 MSPS ratings alone.
Рекомендуется
Industrial Control and Monitoring
AD9023BQ may be used in industrial monitoring equipment for waveforms that need faster capture than a slow sensor ADC but do not require the highest converter resolution. Its 20 MSPS sampling rate provides 20 million samples per second, while the 12-bit output preserves 4,096 possible code levels. The centered -1.024 V to 1.024 V input span is compatible with suitable industrial signal-conditioning circuitry. However, the operating-temperature range, EMC-related ratings, and RoHS status are not present in the supplied data. Industrial deployment should therefore wait until temperature, isolation, grounding, and compliance requirements are verified against the manufacturer datasheet and applicable system standards.

Medical and Test Equipment
AD9023BQ is applicable to research-grade medical instrumentation and electronic test equipment when the acquisition bandwidth and dynamic performance fit the intended signals. A 12-bit converter with a 20 MSPS sampling rate can capture pulsed, transient, or repetitive waveforms for analysis, while the nominal 5 V supply simplifies integration with conventional laboratory circuits. The -1.024 V to 1.024 V analog range still requires front-end attenuation, biasing, and protection appropriate to the measured quantity. Diagnostic or patient-contact applications must not rely on the device's general active-production listing; safety, isolation, operating-temperature, and regulatory requirements need separate verification and may require a different converter.
Рекомендуется
Audio and Vibration Measurement
AD9023BQ can be considered for audio, vibration, and mechanical-response measurements where sampled waveforms must be captured at up to 20 MSPS. The 12-bit quantization level and centered analog input window support broad-band condition monitoring when the transducer, anti-alias filter, and gain stages are properly designed. The converter's sample interval of 50 ns is short enough for transient capture, but practical bandwidth depends on the acquisition circuit and the datasheet timing characteristics, which are not included in the verified record. Engineers should also assess clock-jitter sensitivity, reference stability, and the need for an anti-alias filter rather than equating 20 MSPS directly with a 10 MHz usable bandwidth.
Рекомендуется
Embedded Sensor Signal Processing
AD9023BQ may serve as the acquisition stage in an embedded system that digitizes rapidly changing sensor outputs before filtering or feature extraction. Its 12-bit resolution and 20 MSPS sample rate provide a defined conversion capability for vibration, position, current, and waveform sensors whose analog front ends can drive the -1.024 V to 1.024 V input range. The through-hole 28-CDIP package is well matched to a controller motherboard or instrument chassis. Embedded implementations must budget for a nominal 5 V rail capable of the 240 mA maximum supply current, provide local decoupling, and ensure that clock and data routing do not introduce errors. The operating-temperature and lifecycle details beyond active production remain unverified.

Заметки по проектированию
Do not treat 20 MSPS as a guaranteed 10 MHz signal bandwidth. The practical limit also depends on acquisition time, source impedance, clock jitter, reference accuracy, the analog front end, and the manufacturer timing specifications. Confirm the full input model and timing diagram before selecting input and output termination. Likewise, verify whether the -1.024 V to 1.024 V range is specified for a particular input configuration before designing the source interface.
Place the AD9023BQ in a through-hole layout compatible with its 28-CDIP package and preserve the manufacturer's recommended spacing around analog, reference, clock, and supply connections. Route the sampling clock as a short, controlled-impedance trace and keep high-speed digital outputs away from the analog input. Use a single ground strategy appropriate to the converter architecture; do not split the ground plane unless the datasheet reference design explicitly requires it.
Estimated supply demand using the documented 240 mA maximum current and 5 V nominal voltage is 1.2 W. This is a design estimate rather than a datasheet power figure and does not include analog signal power or regulator losses. The 5 V source must therefore support the converter's current requirement with suitable transient margin, while local decoupling must follow the manufacturer values. Actual dissipation depends on operating conditions and supply voltage.
Clock quality directly affects sampling accuracy in a high-speed converter. Use a low-jitter clock source, keep the clock route short, and observe the voltage and termination requirements in the manufacturer documentation. Provide an anti-alias filter ahead of the ADC and terminate inputs consistently. Because the supplied data does not include the complete pinout, reference circuit, or clock specifications, these requirements must be validated from the authoritative datasheet.
Информация о соответствии
The verified product listings do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The AD9023BQ is listed as active production, but active production does not establish regulatory qualification.
