5962-9470301MYA Обзор
A flash ADC (also called a direct-conversion ADC) is a type of analog-to-digital converter that uses a parallel bank of 2^N - 1 comparators against a resistor-ladder reference to digitize an analog input in a single clock cycle. Within the broader data-converter hierarchy, this places it as: flash ADC -> high-speed ADC -> analog-to-digital converter -> data converter -> mixed-signal IC. Flash architecture is the fastest ADC topology but is power-hungry and area-intensive, limiting practical resolution to roughly 8-10 bits - making this AD9058 die a natural fit for 8-bit 50 MSPS applications where latency and bandwidth dominate over DC accuracy.
Key specifications include 8-bit resolution, 50 MSPS sampling rate per channel, dual simultaneous sampling, parallel CMOS digital outputs, +5 V single-supply operation. The 5962- prefix indicates a DLA/DSCC Standard Microcircuit Drawing part number, which means the device has been through formal MIL-STD-883 Class B screening, including temperature cycling, hermeticity testing, and burn-in. Operating temperature range spans -55 C to +125 C.
The AD9058 architecture uses two independent flash cores fed by wideband input buffers with track-mode bandwidth exceeding 175 MHz. The internal 2.5 V reference is resistor-ladder based and shared between both channels; an external reference override is supported for ratiometric or gain-trimmed operation. A separate output enable pin places the CMOS bus in high-impedance for multi-device sharing of a single parallel data bus.
Typical applications include radar receiver IF digitizers, electronic-warfare front ends, transient-capture digitizers, military sonar baseband digitizers, and medical imaging front-ends (CT, ultrasound beam-formers). The wide analog input bandwidth (175 MHz) and low latency (one clock cycle) make the part well suited to time-interleaved IF sampling where phase coherency between channels is mandatory.
When designing with this part, ensure the analog input is AC-coupled with a 50 ohm source termination to avoid degrading the wideband input stage; add a logic-supply decoupling network even though the part is single-supply, because the CMOS output drivers generate fast edge currents that couple back into the analog rails through the package lead frame.
This page synthesizes DLA SMD cross-reference data, MIL-STD-883 screening information, and practical JLCC layout guidance not consolidated in any single distributor listing, providing engineers with a one-stop reference for hi-rel 8-bit dual-ADC design.

Типичное применение
5962-9470301MYA подходит для 6 применениеs: Radar Receiver IF Digitizer, Electronic Warfare Front-End, Transient-Capture Digitizer, Military Sonar Baseband Digitizer, Medical Imaging Front-End, Test and Measurement Instrumentation.
Radar Receiver IF Digitizer
The 5962-9470301MYA suits radar IF digitization where two channels (I and Q) must sample simultaneously with deterministic latency. The 50 MSPS per channel rate covers IF bandwidths through 25 MHz while the 175 MHz analog input bandwidth allows undersampling of higher IFs, simplifying the receiver by eliminating a downconversion stage. Dual simultaneous sampling keeps I/Q channel-to-channel skew at sub-nanosecond levels critical for coherent pulse-Doppler processing, and the MIL-STD-883 screening ensures reliable operation across the -55 C to +125 C military temperature range required by airborne and shipboard radar platforms.
Рекомендуется
Electronic Warfare Front-End
Electronic-warfare receivers require wideband instantaneous capture of threat signals, and the 5962-9470301MYA's 175 MHz analog input bandwidth combined with 50 MSPS per channel throughput makes it suitable for digital RF memory (DRFM) applications. The two channels can capture orthogonal polarization paths simultaneously, while the parallel CMOS output interface feeds directly into FPGA-based storage without requiring an intermediate serializer. MIL-STD-883 Class B screening provides the radiation-tolerance baseline and extended temperature range that military EW platforms mandate for mission-critical signal capture.
Рекомендуется
Transient-Capture Digitizer
High-energy physics experiments and lightning-strike instrumentation require digitizers that can capture single-shot transient events with microsecond-to-millisecond duration while preserving leading-edge detail. The 5962-9470301MYA's flash architecture delivers conversion in a single clock cycle, eliminating pipeline delay so the digitizer can trigger and capture without missing the first edge. Dual channels allow simultaneous capture of the event plus a reference channel for baseline subtraction. The hermetic JLCC package and military temperature range are essential for accelerator and outdoor test-range environments where humidity and thermal cycling would degrade plastic-packaged commercial parts.

Military Sonar Baseband Digitizer
Towed-array and hull-mounted sonar systems digitize hydrophone signals at baseband after analog beamforming, and the 5962-9470301MYA's two-channel configuration aligns naturally with orthogonal beamformer outputs or with summed/difference channels from a preformed beam. The 50 MSPS rate covers acoustic bandwidths through 25 MHz for high-resolution synthetic aperture sonar, while MIL-STD-883 Class B screening ensures reliability under the 10 g vibration and -55 C to +125 C thermal stress typical of submarine deployments. The low-latency flash conversion also enables real-time acoustic transient detection (e.g., torpedo or marine-mammal classifiers) without buffering delay.
Рекомендуется
Medical Imaging Front-End
CT scanner and ultrasound beam-former front ends digitize multiple detector channels at high speed with deterministic channel-to-channel timing, and the 5962-9470301MYA's dual-channel simultaneous sampling is a natural fit for time-interleaved detector arrays. The 50 MSPS per channel rate supports ultrasound I/Q demodulation at carrier frequencies through 25 MHz with 8 bits of dynamic range suitable for envelope detection. The MIL-STD-883 screening and wide operating temperature range are essential for portable field-deployable medical imaging systems where temperature variation and mechanical shock are routine. Where higher resolution is needed, multiple 5962-9470301MYA parts can be time-interleaved.
Рекомендуется
Test and Measurement Instrumentation
Automated test equipment and digital oscilloscope front ends need fast, dual-channel digitizers with wide analog bandwidth to characterize high-speed signals. The 5962-9470301MYA's 175 MHz input bandwidth and 50 MSPS per channel throughput support 8-bit oscilloscope or sampling-channel applications up to 25 MHz signal bandwidth with two channels captured simultaneously. The CMOS parallel output directly feeds an FPGA-based capture buffer without serializer latency, and the MIL-STD-883 screening allows the same hardware to qualify for both laboratory and field-deployable test sets. The 3-state output enable allows multiple ADCs to share a common data bus for higher-channel-count instruments.

Заметки по проектированию
Estimated: For the 44-pin JLCC footprint, place a continuous ground pour under and around the package with at least 4 vias per side stitching the top ground pour to an inner ground plane. The analog inputs (pins 26, 35, 36) should be routed as 50 ohm controlled-impedance microstrip on the top layer with the ground plane directly underneath - no vias on the input traces to avoid stub inductance that degrades the 175 MHz bandwidth.
The 5962-9470301MYA has separate AVDD (pin 28) and DVDD (pin 15) supplies that should be powered from a common +5 V rail but isolated by ferrite beads to break ground-loop noise coupling. Place 10 uF tantalum and 0.1 uF ceramic bypass capacitors as close as possible to both supply pins. The internal 2.5 V reference (pin 1) must be decoupled with a 1 uF ceramic to AGND - omitting this capacitor allows reference ringing that shows up as code-dependent noise in the ADC output spectrum.
The encode (sample clock) input at pin 2 should be driven from a low-jitter clock source - clock jitter directly degrades SNR by the formula SNR_jitter = 20*log10(2*pi*fIN*jitter). For 50 MSPS operation at 175 MHz analog input, total RMS jitter must be below 5 ps to preserve ENOB above 7 bits. Use a dedicated clock buffer with sub-picosecond additive jitter rather than routing the system clock through a long FPGA trace.
Do not AC-couple the analog inputs without providing the input bias return path - the AD9058 input stage is internally biased to mid-supply, and adding a series AC-coupling capacitor without a DC return to mid-supply will saturate the input. Drive differentially via a 1:1 transformer (e.g., Mini-Circuits ADT1-1WT) with the secondary center tap pulled to mid-supply through a resistor to AGND. Single-ended drive is acceptable only when AC-coupling with a DC bias network is explicitly designed in.
