ADS5411IPJYRG3 Overview
An analog-to-digital converter (ADC) is a data-acquisition component that samples continuous analog signals and outputs discrete digital codes, forming the bridge between the analog front end and the digital signal-processing domain. Within the broader semiconductor taxonomy, ADCs belong to data-converter ICs, which sit inside signal-chain semiconductors and ultimately under the mixed-signal IC umbrella. Pipelined ADCs in particular use a multi-stage architecture to achieve high sampling rates while keeping per-stage hardware modest, making them the workhorse choice for intermediate-speed, moderate-resolution IF, instrumentation, and imaging applications.
Key features of the ADS5411 include an integrated input buffer for source isolation, a low-noise clock interface with LVPECL/LVDS/LVCMOS compatibility, and 3.3V CMOS outputs that simplify interfacing with FPGAs, ASICs, and DSPs without level shifters. The part uses a single 5V analog supply and a 3.3V digital supply, with a digital-down-format option for flexible data capture.
The device uses a multi-stage pipelined architecture with proprietary calibration, providing excellent spurious-free dynamic range (SFDR) and signal-to-noise ratio (SNR) at the rated 105 MSPS. A differential clock input supports on-chip clock-doubler operation, while the integrated input buffer eliminates the need for an external high-bandwidth ADC driver in many systems. The 52-QFP footprint offers generous thermal headroom and good PCB manufacturability for prototype builds.
Typical applications include communications IF-signal digitization, industrial test and measurement equipment, medical imaging front ends, radar and sonar intermediate-frequency sampling, and high-speed data acquisition cards. Its 11-bit resolution strikes a balance between dynamic range and system cost where 8-bit ADCs are too coarse but 14-bit parts are unnecessary.
When designing with the ADS5411, ensure that the analog input is AC-coupled and properly terminated, since the on-chip input buffer expects a 2.2 Vp-p differential swing. Pay close attention to PCB layout - separate analog and digital ground planes and place bypass capacitors as close to the supply pins as possible to achieve the published SNR and SFDR numbers.

Typical Applications
ADS5411IPJYRG3 is suitable for 6 applications: Communications IF-Signal Digitization, Industrial Test and Measurement Equipment, Medical Imaging Front Ends (Ultrasound IF), Radar and Sonar IF Sampling, High-Speed Data Acquisition Cards, Video and Broadcast Signal Processing.
Communications IF-Signal Digitization
The ADS5411IPJYRG3 fits communications IF-signal digitization because it samples at 105 MSPS with 11-bit resolution, enabling direct IF sampling of second- or third-stage intermediate frequencies in software-defined radio receivers and cellular base-station cards. The integrated input buffer isolates the on-chip track-and-hold from the external signal source, eliminating the need for a separate high-bandwidth ADC driver and reducing BOM cost and board area. With 3.3 V CMOS outputs, the ADC connects directly to FPGAs or DSPs without level shifters, simplifying baseband datapaths. Designers typically use the part between the analog mixer output and the FPGA's digital down-conversion (DDC) block, achieving the dynamic range needed for demodulation while keeping the data rate within manageable DSP bandwidths.
Recommended
Industrial Test and Measurement Equipment
For industrial test and measurement instruments such as oscilloscopes, spectrum analyzers, and digitizers, the ADS5411IPJYRG3 provides 105 MSPS sampling with 11-bit resolution - sufficient for capturing repetitive signals and single-shot transients in mid-bandwidth test gear. The single 5 V analog supply and 3.3 V digital supply simplify the analog front-end power tree, while the 52-QFP package offers generous thermal headroom for continuous-conversion duty cycles typical of production-line testers. Compared with lower-speed ADCs, the 105 MSPS throughput enables wider real-time bandwidth, and the on-chip input buffer maintains signal integrity across long input traces on mixed-signal test boards.
Recommended
Medical Imaging Front Ends (Ultrasound IF)
In medical ultrasound and similar medical-imaging front-end designs, the ADS5411IPJYRG3 serves as an IF-sampling ADC after the analog beamformer or TGC stage. The 105 MSPS sample rate supports typical ultrasound IF frequencies in the 10-40 MHz band, while 11-bit resolution matches the dynamic range requirements of B-mode imaging channels. The integrated input buffer simplifies the per-channel front end, reducing component count - critical for dense multi-channel probe designs where PCB real estate is at a premium. Operating from a single 5 V analog rail, the ADC integrates cleanly with the analog receiver chain used in cart-based and portable ultrasound systems.
Recommended
Radar and Sonar IF Sampling
The ADS5411IPJYRG3 fits radar and sonar intermediate-frequency sampling chains where pulse-compression waveforms and Doppler processing demand wide instantaneous bandwidth. At 105 MSPS, the ADC captures IF signals in the 20-50 MHz range with adequate oversampling for matched-filter processing, while 11-bit resolution preserves the signal-to-noise ratio needed for target detection. The differential analog input and on-chip input buffer reject common-mode noise from long analog traces between the front-end mixer and the ADC, while 3.3 V CMOS outputs feed directly into FPGA-based matched-filter or FFT processors used in radar signal-processing pipelines.
Recommended
High-Speed Data Acquisition Cards
For high-speed PCI/PXI data-acquisition cards used in laboratory and OEM test systems, the ADS5411IPJYRG3 provides a single-channel 105 MSPS sampling engine that interfaces to FPGAs for on-board buffering and triggering. The 52-QFP footprint is friendly to multilayer PCB layouts typical of 6U or 3U card designs, and the 5 V analog supply pairs with standard on-card power rails without additional regulation. The 3.3 V CMOS digital interface is directly compatible with FPGA I/O banks, simplifying timing closure on multi-channel synchronisation schemes across multiple cards.
Recommended
Video and Broadcast Signal Processing
In broadcast and professional video equipment, the ADS5411IPJYRG3 can sample intermediate-frequency or baseband video signals at up to 105 MSPS. The 11-bit resolution supports standard-definition and high-definition video digitisation with adequate headroom for broadcast-grade signal-to-noise performance, while the integrated input buffer eliminates the need for an external video op-amp driver. Designers typically place the ADC after the analog video decoder and feed the 3.3 V CMOS outputs into an FPGA-based video processing pipeline for scaling, de-interlacing, and compression.

Key Differentiators
- Integrated input buffer eliminates external ADC driver (vs ADS5424IPJY)
- 11-bit resolution hits the cost-performance sweet spot (vs ADS5424IPJY)
- Single 5 V analog supply simplifies power tree (vs ADS5423IPGP)
Design Notes
Use separate analog and digital ground planes joined at a single point near the ADC. Place 0.1 uF ceramic bypass capacitors as close as possible to each AVdd and DVdd pin, with a 10 uF tantalum bulk capacitor on each supply rail. This star-ground topology preserves SNR and SFDR, which are highly sensitive to digital switching noise coupling into the analog section.
Drive the analog input differentially with a 2.2 Vp-p swing centered around the on-chip VCM (2.4 V) output. AC-couple the analog input through a transformer or AC-coupling network to remove DC bias. Use controlled-impedance (typically 50 ohm or 100 ohm differential) transmission lines for the analog input and clock traces, and route clock and analog inputs orthogonally to avoid coupling.
Do not skip the VREF decoupling capacitors (typically 10 uF + 0.1 uF in parallel). Do not drive the analog input with a single-ended source without a proper bias network - the input buffer expects a differential signal. Avoid using long, non-controlled-impedance traces for the CMOS data outputs to prevent digital timing skew; route the 11-bit data bus with matched lengths if capturing into an FPGA.
Compliance Information
RoHS compliant per TI product page. The ADS5411IPJYRG3 is an industrial-grade part (-40C to +85C) and is not AEC-Q100 qualified; it is intended for industrial, communications, and instrumentation use rather than automotive safety-critical applications.
