ADS5424IPJYG3 概述
An analog-to-digital converter (ADC) is a mixed-signal data converter that samples a continuous-time analog input voltage and produces a discrete-time digital code proportional to the input amplitude. Within the broader data-converter hierarchy, the ADS5424 belongs to the high-speed pipelined ADC family, which sits above SAR and delta-sigma converters in the sampling-rate taxonomy and is the architecture of choice for IF/RF digitization above 10 MSPS. This positioning makes it directly relevant to radar, software-defined radio, medical imaging, and high-end instrumentation front-ends.
Key features of the ADS5424 include an integrated input buffer, internal reference, and a 14-bit LVCMOS-compatible parallel output bus. The device supports both single-ended and differential drive topologies, and its internal dither circuit improves small-signal linearity in the presence of coherent inputs. Differential non-linearity (DNL) is specified at +/-0.6 LSB and integral non-linearity (INL) at +/-1.5 LSB, providing engineers with the headroom needed for spectral analysis at high input frequencies.
The architecture is a multi-stage switched-capacitor pipeline with on-chip sample-and-hold, error correction, and digital post-processing. This topology is responsible for the 1.9 W power figure and the 52-pin PowerPAD-enhanced QFP thermal envelope, which is required because the digital outputs and analog front-end share a common substrate. The exposed die pad (PowerPAD) must be soldered to a ground plane to maintain the published thermal resistance of approximately 22 C/W (junction-to-ambient on a 4-layer JEDEC test board).
Typical applications for the ADS5424IPJYG3 include high-IF sampling in cellular base-station receivers, digital oscilloscopes and spectrum analyzers, defense radar and EW systems, and medical imaging front-ends such as ultrasound beamformers. The 105 MSPS sampling rate, combined with the 2.2 Vpp input range, also makes it a candidate for cable-headend equipment and professional video digitizers. In all of these applications, the device replaces legacy 12-bit pipelines where extra dynamic range is required without a significant cost or power penalty.
When designing with the ADS5424, careful attention must be paid to the analog input network: a differential transformer drive with back-to-back clipping diodes and 50-ohm source terminations is the recommended pattern. A low-impedance ground plane directly under the PowerPAD is essential for thermal performance, and the 3.3 V digital supply should be decoupled with 0.1 uF and 10 uF capacitors placed within 5 mm of the DVDD pins.
This page synthesizes distributor stock, verified drop-in alternatives, and practical design notes that are not found in the standalone manufacturer datasheet, giving engineers a single, actionable reference for the ADS5424IPJYG3.

典型应用
ADS5424IPJYG3 适用于 6 应用s: High-IF Communications Receiver, Digital Oscilloscope and Spectrum Analyzer, Defense Radar and EW Front-End, Medical Ultrasound Beamformer, Cable Headend and Professional Video Digitiser, Industrial Process Control and Data Acquisition.
High-IF Communications Receiver
The ADS5424IPJYG3 digitises intermediate-frequency signals up to about 52 MHz in cellular base-station and software-defined radio receivers, where its 105 MSPS sample rate supports second-Nyquist placement without aliasing. The 2.2 Vpp differential input range and 74 dBc SNR provide the headroom needed for multi-carrier GSM/UMTS/CDMA front-ends, and the 3.3 V CMOS outputs interface directly to FPGAs. Internal dither improves small-signal linearity on coherent inputs, which is critical when digitising narrowband carriers. A typical front-end uses a balun and 50-ohm termination to drive AINP/AINM.
推荐
Digital Oscilloscope and Spectrum Analyzer
Bench-top oscilloscopes and spectrum analyzers in the 100-200 MHz class use the ADS5424IPJYG3 as the front-end ADC, where its 14-bit resolution extends vertical accuracy beyond legacy 8-bit parts. The 93 dBc SFDR keeps internal spurs below the noise floor of mid-bandwidth signal analysis, and the 1.9 W dissipation is well within the thermal budget of a fan-cooled bench instrument. The 52-pin HLQFP package is straightforward to lay out on a 4-layer FR-4 motherboard and the CMOS outputs feed directly into an FPGA or DSP for FFT processing. This is one of the highest-volume use-cases for the part.
推荐
Defense Radar and EW Front-End
The ADS5424IPJYG3 is widely deployed in phased-array radar and electronic-warfare receivers where 14-bit dynamic range and 93 dBc SFDR are needed to resolve small radar returns in the presence of strong jammers. The industrial -40 C to +85 C temperature range and the optional MIL-PRF-38535 variant (ADS5424MPJYEP) make the die suitable for both ground-mobile and airborne platforms. The 105 MSPS rate is well matched to the bandwidth of typical IF stages in X-band radar. Designers typically pair the part with a Xilinx Kintex or TI Keystone DSP for pulse compression.
推荐
Medical Ultrasound Beamformer
In medical ultrasound systems, the ADS5424IPJYG3 is used in the beamformer analog front-end where 14-bit resolution and 105 MSPS enable the simultaneous digitisation of multiple transducer channels. The differential input and transformer drive simplify the analog front-end, while the parallel CMOS outputs feed an FPGA-based delay-and-sum beamformer. The 74 dBc SNR is sufficient for second-harmonic imaging modes, and the 1.9 W power dissipation is acceptable for a cooled cart-based console. The part's industrial temperature range covers clinical environments reliably.
推荐
Cable Headend and Professional Video Digitiser
Cable-TV headend equipment and broadcast video digitisation cards use the ADS5424IPJYG3 to sample baseband or modulated video at 105 MSPS. The 14-bit resolution supports SMPTE-292M HD-SDI and similar professional standards with margin to spare, and the 2.2 Vpp input range covers typical 1 Vpp video signals with up to 6 dB of headroom. The 3.3 V CMOS outputs are directly compatible with broadcast video FPGAs, and the 52-pin HLQFP is easy to lay out on a multi-channel video capture card. The high SFDR helps maintain a clean eye pattern at high modulation rates.
推荐
Industrial Process Control and Data Acquisition
Multi-channel industrial data-acquisition systems use the ADS5424IPJYG3 to digitise vibration, acoustic-emission, and high-speed sensor signals at 105 MSPS, where the 14-bit resolution provides the dynamic range needed for transient capture. The differential input rejects common-mode noise from industrial plant environments, and the parallel CMOS interface simplifies the timing closure of the FPGA capture logic. The 5 V analog supply is well regulated on industrial 24V-bus systems, and the -40 C to +85 C industrial temperature range is sufficient for cabinet-mounted deployments. The 1.9 W power is acceptable in multi-channel fan-cooled chassis.

设计说明
Solder the exposed PowerPAD (pin 53) to a continuous ground plane on the top layer of the PCB to achieve the 22 C/W junction-to-ambient thermal resistance quoted in the datasheet. Use thermal vias in a 3x3 grid under the pad to connect to internal ground planes. The ground plane should be a low-impedance analog ground, not a noisy digital ground. This is critical because at 1.9 W total dissipation, the junction temperature rises 42 C above ambient on a properly designed board.
Use a 1:1 transformer (for example Mini-Circuits ADT1-1WT or equivalent) to drive the AINP/AINM differential analog input, with 50-ohm source terminations on each leg and back-to-back signal diodes to the VCM node for overdrive protection. Keep the input traces length-matched to within 1 mm and route them away from the parallel CMOS outputs. Place 0.1 uF and 10 uF decoupling capacitors within 5 mm of every AVDD pin, and 0.1 uF ceramics within 5 mm of every DVDD pin. Improper decoupling is the most common cause of degraded SFDR in this part family.
Route the CLKP/CLKN differential clock as a 100-ohm differential pair, length-matched to within 1 mm, and AC-couple if driving from a non-common-mode-compatible source. Use an extremely low-jitter clock (RMS jitter < 1 ps) to preserve the datasheet SNR - 1 ps of additional clock jitter degrades SNR by approximately 2 dB at 105 MSPS. For multi-board synchronisation, distribute the clock from a single low-noise source such as a TI CDCE72010 or a crystal oscillator with sub-ps jitter. The DRDY output can be used downstream for sample-domain alignment.
合规信息
The G3 suffix in the orderable part number indicates RoHS-compliant green packaging per TI's nomenclature. The ADS5424IPJYG3 is not AEC-Q100 qualified; for defense applications choose the ADS5424MPJYEP variant.
