ADS5440IPFPRG4 概要
A pipeline ADC (pipelined analog-to-digital converter) is a type of high-speed data converter that processes analog signals through cascaded low-resolution stages, with each stage sampling and converting a portion of the signal before passing the residue to the next stage. Pipeline ADCs sit at the top of the converter hierarchy as: pipeline ADC -> ADC -> data converter -> signal chain IC -> semiconductor. They are the workhorse architecture for communications, test and measurement, and defense applications where sample rates from 100 MSPS to 500 MSPS are required.
Key features include 210 MSPS maximum sample rate, 13-bit resolution, 0.0269% integral nonlinearity (INL) error, and LVDS digital outputs that minimize switching noise coupling into sensitive analog circuitry. The dual-suprail architecture (5 V analog, 3.3 V digital) is a hallmark of high-performance converters, isolating noisy digital transients from precision analog sampling. The TQFP PowerPAD package provides a thermal resistance suitable for continuous 210 MSPS operation.
The ADS5440 uses a switched-capacitor pipeline architecture with internal track-and-hold, supporting input bandwidths well above Nyquist. The recommended driver configuration pairs the ADC with the THS4509 fully-differential op amp set to provide 50 ohm termination and the 2.4 V common-mode input voltage required by the ADC's input network. On-chip references and an internal reference buffer simplify external BOM.
Typical applications include communications basestation receivers (multi-carrier GSM, CDMA, WCDMA, LTE), radar and electronic warfare digitizers, test and measurement instrumentation, and medical imaging front-ends. The 210 MSPS sample rate enables IF sampling of intermediate-frequency signals up to 200 MHz, eliminating downconversion stages in receiver chains.
When designing with the ADS5440, follow TI's recommended input network: a differential THS4509 driver with 50-ohm source termination, 2.4 V common-mode bias, and a 100-ohm differential load on the ADC input pins. Decouple the 5 V analog and 3.3 V digital supplies with 0.1 uF and 10 uF ceramic capacitors placed within 5 mm of each supply pin. Use controlled-impedance differential routing (100 ohm differential) for the LVDS output pairs, with 100-ohm termination at the receiver.

ADS5440IPFPRG4 の用途: 6 件s: Communications Basestation Receiver, Radar and Electronic Warfare Digitizer, Test and Measurement Instrumentation, Medical Ultrasound Receiver, Software Defined Radio Front-End, Industrial Non-Destructive Testing.
Communications Basestation Receiver
The ADS5440IPFPRG4's 210 MSPS sample rate and 13-bit resolution make it ideal for digitizing wide-bandwidth IF signals in multi-carrier GSM, CDMA, WCDMA, and LTE basestation receivers. Its LVDS outputs feed directly to an FPGA digital downconverter (DDC) for channelization. The 5 V analog / 3.3 V digital dual-supply architecture isolates noisy LVDS switching from the precision sampling front-end, while the 2.4 V common-mode input is easily biased by a THS4509 fully-differential driver. Compared to lower-speed ADCs, the 210 MSPS rate allows direct sampling of IFs up to 200 MHz, eliminating a downconversion stage and reducing BOM. SNR and SFDR performance are sufficient for 12+ dB margin on 64-QAM modulation.

Radar and Electronic Warfare Digitizer
In radar and EW receivers, the ADS5440IPFPRG4's 210 MSPS rate captures wideband IF signals from L-band through S-band with sufficient bandwidth for pulse-to-pulse phase tracking. The 13-bit resolution preserves signal fidelity for matched-pulse detection algorithms while keeping power and cost manageable. The TQFP PowerPAD package handles continuous 210 MSPS operation with proper thermal vias. Pair the ADC with a low-noise LDO such as TPS7A4701 for the 5 V analog rail to maximize SFDR; feed the LVDS outputs to an FPGA Kintex or Virtex-class device. The military-grade ADS5440MPFPEP variant extends temperature range to -55 C to +125 C for airborne EW applications.
おすすめ
Test and Measurement Instrumentation
The ADS5440IPFPRG4 serves as the front-end digitizer in high-end oscilloscopes, spectrum analyzers, and arbitrary waveform digitizers where 210 MSPS sampling captures repetitive and single-shot transients with 13-bit amplitude resolution. The BiCom3X bipolar process provides low distortion and wide analog input bandwidth, essential for accurate capture of fast-edged signals. The LVDS digital interface simplifies routing to a high-pin-count FPGA back-end processor. Combined with a THS4509 driver and a low-jitter clock source, this ADC enables instrumentation with ENOB exceeding 10 bits across a wide input frequency range, suitable for compliance test, signal-integrity analysis, and wideband RF measurement.
おすすめ
Medical Ultrasound Receiver
In mid-range medical ultrasound systems, the ADS5440IPFPRG4 digitizes beamformed RF signals at 210 MSPS with 13-bit resolution, providing sufficient dynamic range for harmonic imaging modes. The differential input rejects common-mode noise from beamformer ASICs, while the 5 V supply rail ensures sufficient full-scale range for low-level echo returns. Multiple ADS5440 channels (one per receive channel) feed LVDS data into an FPGA back-end for digital beamforming and Doppler processing. The exposed thermal pad enables high-density multi-channel PCB layouts without external heatsinking. The ADC's low power consumption keeps per-channel thermal load within budget for portable cart-based ultrasound systems.
おすすめ
Software Defined Radio Front-End
Software defined radio (SDR) platforms use the ADS5440IPFPRG4 to digitize IF outputs from RF tuner stages at sample rates up to 210 MSPS, enabling direct digital downconversion of wide-bandwidth signals in an FPGA or DSP. The 13-bit resolution balances dynamic range against power for mobile and portable SDR deployments. The ADC's wide analog input bandwidth exceeds 500 MHz, allowing direct sampling of L-band and S-band signals without external mixers. The LVDS output pairs simplify routing to a Kintex-7 or similar FPGA. When SDR platforms require higher sample rates, the footprint-compatible ADS5474IPFP (14-bit, 400 MSPS) provides an upgrade path without PCB rework.
おすすめ
Industrial Non-Destructive Testing
Industrial ultrasonic and eddy-current non-destructive testing (NDT) equipment uses the ADS5440IPFPRG4 to digitize wideband transducer signals at 210 MSPS, capturing high-frequency content needed to resolve sub-millimeter flaws in welds, composites, and metal castings. The 13-bit dynamic range supports both low-amplitude first-arrival detection and high-amplitude reflection capture. The industrial -40 C to +85 C operating range supports factory floor environments, while the LVDS outputs interface cleanly to industrial FPGA SoCs. The exposed thermal pad ensures reliable 24/7 operation at continuous 210 MSPS rates. Combined with a THS4509 driver, this ADC delivers the timing precision required for time-of-flight diffraction (TOFD) flaw detection.

設計ノート
Use controlled-impedance 100-ohm differential routing for the LVDS output pairs from the ADS5440 to the FPGA. Match lengths within each pair to within 0.5 mm (20 mils) to avoid introducing skew. Place 100-ohm differential termination at the FPGA receiver, not at the ADC end, to maximize signal integrity at 210 MSPS data rates. Each LVDS pair should be ground-referenced and routed over a continuous ground plane.
Decouple the 5 V analog (AVDD) and 3.3 V digital (DRVDD) supplies with 10 uF tantalum or ceramic bulk capacitors plus 0.1 uF ceramic bypass capacitors placed within 5 mm of each supply pin. Use a ferrite bead or pi-filter between the 5 V analog and 3.3 V digital supplies to isolate the noisy LVDS switching transients from the precision analog sampling. Power the 5 V rail from a low-noise LDO such as the TPS7A4701 for maximum SFDR.
Per the TI ADS5440 datasheet, drive the differential analog inputs with a THS4509 fully-differential op amp providing 50-ohm source termination and 2.4 V common-mode bias. The 50-ohm source termination is critical because the ADC's input network is designed for source-matched operation; without it, frequency response peaking and ringing will appear at high IF inputs, degrading ENOB. Keep the input trace length under 25 mm and use 50-ohm controlled-impedance routing.
Solder the exposed thermal pad of the TQFP PowerPAD package to a continuous ground plane with a thermal via array (8 to 12 vias, 0.3 mm drill) to dissipate the ADC's continuous power dissipation at 210 MSPS. Without proper thermal pad soldering, junction temperature can exceed 125 C and trigger thermal shutdown or reduce ADC reliability. Avoid cutting thermal vias under the pad, which would block heat transfer to internal ground planes.
A common design mistake is using a single-ended op-amp driver instead of a fully-differential driver for the ADS5440 inputs, which causes even-order harmonic distortion (HD2) and degrades SFDR by 10-20 dB. Another pitfall is using a high-jitter clock source (e.g., FPGA-generated clock without jitter cleaning), which directly raises the ADC noise floor by SNR_dB = 20*log10(1/(2*pi*fIN*tJ)). Always use a low-jitter clock synthesizer such as the CDCE72010 with sub-ps RMS aperture jitter for IF sampling above 100 MHz.
コンプライアンス情報
Pb-free and RoHS compliant per the 'G4' suffix in the part number. Not AEC-Q100 qualified (this is a high-speed data converter, not an automotive analog IC). For military-grade temperature range (-55 C to +125 C), use the ADS5440MPFPEP variant.
