ADS5444HFG/EM Présentation
A pipelined ADC (also called a sub-ranging flash ADC) is a high-speed data converter architecture that processes the analog input through a cascade of low-resolution flash stages, each producing a partial digital estimate that is combined in a digital correction network. Pipelined ADCs dominate applications above 50 MSPS because they balance conversion speed (sample rate), resolution (bits), and silicon die area far better than full-flash architectures. Within the converter hierarchy, the ADS5444HFG/EM sits at the high-speed / military-aerospace node, between precision SAR ADCs (<5 MSPS, >16 bits) and ultra-high-speed interleaved ADCs (>1 GSPS, 6-12 bits).
Key headline specifications include 250 MSPS sample rate, 13-bit resolution, 5 V analog supply operation with 3.3 V LVDS digital I/O, 2.2 Vp-p full-scale analog input, and 410 mA typical supply current. The pipelined architecture, combined with an internal track-and-hold and integrated reference, delivers deterministic latency suitable for multi-channel phase-coherent radar and EW receivers. Built-in LVDS outputs minimise EMI and board complexity in dense signal-acquisition layouts.
Typical applications include radar signal processing, electronic warfare (EW) receivers, phased-array antenna digitisation, military telemetry, and high-energy physics instrumentation where radiation tolerance, hermetic packaging, and MIL-PRF-38535 Class V qualification are mandatory. The ceramic HFG package offers 84 gull-wing leads on a 40.77 x 40.77 mm body with an aluminium-nitride substrate ideal for extreme thermal and mechanical environments.
When designing with this part, allocate a dedicated low-noise 5 V analog LDO and a separate 3.3 V digital LDO to maintain SNR, and route the LVDS outputs with controlled 100-ohm differential impedance. Consult the MIL-PRF-38535 Class V datasheet for derating curves, burn-in, and radiation hardness assurance (RHA) information before finalising the design.

Applications typiques
ADS5444HFG/EM convient pour 6 applications: Phased-Array Radar Digitiser, Electronic Warfare (EW) Receiver, Military Telemetry Acquisition, High-Energy Physics Instrumentation, Wideband Software-Defined Radio (SDR), Signal Intelligence (SIGINT) Receiver.
Phased-Array Radar Digitiser
The ADS5444HFG/EM suits phased-array radar digitiser channels where 250 MSPS, 13-bit resolution, and deterministic pipelined latency are required. The integrated input buffer and track-and-hold maintain phase coherence across multiple channels, while the QMLV Class V qualification and 84-pin hermetic ceramic HFG package support the wide -55C to +125C temperature range and radiation environments typical of airborne and shipboard radar. Pair with an LMK04832 clock jitter cleaner and an FPGA-based digital down-converter to implement coherent beamforming. The LVDS digital interface minimises EMI in densely populated RF signal-acquisition PCBs and simplifies routing back to the processing FPGA.
Recommandé
Electronic Warfare (EW) Receiver
The ADS5444HFG/EM is well-suited to electronic warfare receiver front-ends that demand high sample rate, MIL-spec reliability, and proven supply-chain integrity. The 250 MSPS, 13-bit architecture captures wide instantaneous bandwidth for IF sampling of threat-signal intercept receivers, while the 5 V analog supply and 2.2 Vp-p input range match common RF downconverter output levels. The MIL-PRF-38535 QMLV Class V qualification includes radiation hardness assurance, making the part viable for high-altitude EW platforms. Use with an RF AGC stage, an IF amplifier, and a Virtex-6 or Kintex-7 FPGA for pulse detection and de-interleaving.
Recommandé
Military Telemetry Acquisition
The ADS5444HFG/EM enables high-fidelity telemetry data acquisition in flight-test instrumentation, missile telemetry, and range-safety applications where MIL-spec qualification is mandatory. The 13-bit resolution captures dynamic-range variations in vibration, strain-gauge, and sensor-array signals, while the 250 MSPS sample rate handles wideband multiplexed sensor channels. The hermetic ceramic HFG package and Class V screening protect against humidity, vibration, and thermal-cycling stresses typical of high-g flight environments. Pair with an instrumentation amplifier front-end and an FPGA frame formatter to implement IRIG-106 Chapter 10 telemetry downlink chains.
Recommandé
High-Energy Physics Instrumentation
The ADS5444HFG/EM supports high-energy physics experiments and accelerator instrumentation where radiation tolerance and long-term reliability are required. The QMLV Class V qualification includes radiation hardness assurance (RHA) data, while the hermetic ceramic HFG package provides mechanical stability in cryostat and vacuum-chamber environments. The 250 MSPS, 13-bit pipeline digitises photomultiplier, Cherenkov, and calorimeter detector front-ends with deterministic latency ideal for time-of-flight measurement. Use in conjunction with a fibre-optic data link and a radiation-tested FPGA such as the Xilinx Virtex-4QV or Microsemi RTG4 for space-deployed experiments.
Recommandé
Wideband Software-Defined Radio (SDR)
The ADS5444HFG/EM can serve as the digitiser core in wideband military SDR receivers covering HF, VHF, and UHF bands. The 250 MSPS sample rate, 13-bit resolution, and pipelined architecture deliver sufficient spurious-free dynamic range (SFDR) for HF through L-band signal capture, while the MIL-PRF-38535 Class V qualification enables deployment in tactical manpack, vehicular, and airborne SDR platforms. The LVDS outputs interface directly to a Kintex-7 FPGA hosting DDC and channeliser IP. Use with an RF front-end LNA/mixer and a fast-settling NCO synthesiser for tunable multi-band operation.
Recommandé
Signal Intelligence (SIGINT) Receiver
The ADS5444HFG/EM fits wide-bandwidth SIGINT intercept receivers that digitise large RF segments for downstream spectral analysis and emitter geolocation. Its 250 MSPS / 13-bit pipeline provides wide instantaneous bandwidth and good linearity for carrier detection, while the QMLV Class V qualification and hermetic packaging support deployment in unattended ground sensors and airborne pods. The integrated input buffer and track-and-hold deliver a flat frequency response across the Nyquist band. Use with a multi-channel phase-coherent LO distribution scheme and a Kintex UltraScale FPGA for cross-channel time-difference-of-arrival (TDOA) processing.

Principaux différenciateurs
- QMLV Class V screening for MIL-STD applications (vs ADS5444 (commercial, plastic))
- Hermetic ceramic HFG package for extreme environments (vs ADS5444 (LQFP-64 plastic))
- Integrated input buffer isolates source from internal switching (vs Discrete input-buffer + pipelined ADC approach)
Notes de conception
Use separate low-noise LDOs for the 5 V AVDD and 3.3 V DRVDD rails - e.g. a TPS7A4701 for the analog rail and a TPS7A3001 for the digital rail - to prevent switching noise from the LVDS outputs from coupling back into the analog signal path and degrading SNR. Place 10 uF and 0.1 uF ceramic bypass capacitors adjacent to every AVDD and DRVDD pin, and use a ground-starved input rather than split-plane routing to maintain clean analog ground return paths.
Route the 13 LVDS data pairs and the LVDS clock pair with controlled 100-ohm differential impedance on the ceramic HFG PCB. Keep LVDS traces short (<5 cm when feasible), and 100-ohm terminate each pair at the receiver with a high-precision resistor network. Avoid routing LVDS over plane splits - use a solid DRVDD reference plane and stitch ground vias densely along the route.
The ceramic 84-pin HFG package is hermetic but requires careful handling - avoid mechanical stress on the leads, and follow MIL-STD-883 ESD protocols during assembly. When prototyping, request the ADS5444MPFPEP engineering grade first to validate signal-chain performance before committing to ADS5444HFG/EM Class V production units. Always confirm the lot acceptance test (LAT) and radiation hardness reports from TI for QMLV Class V designs.
