ADC1412D125HN-C18 Übersicht
A pipelined ADC is a high-speed successive-approximation architecture that breaks the conversion into low-resolution stages with inter-stage residue gain and digital error correction. The pipelined topology trades latency (typically 6-10 clock cycles) for very high sample rates, making it the dominant architecture above 50 MSPS. Dual-channel pipelined ADCs such as the ADC1412D sit in the broader hierarchy of data-converter ICs: ADC -> data converter -> signal-chain IC -> mixed-signal semiconductor, and they are commonly deployed alongside op-amps, clock generators, and FPGA/ASIC capture logic.
The ADC1412D125HN-C18 supports 1.5 Vp-p full-scale differential inputs with typical 1.1 GHz analog input bandwidth. Per-channel SNR is on the order of 71 dBFS and SFDR is in the 85 dBc region, giving a usable dynamic range suitable for communications baseband, medical imaging front-ends, and instrumentation digitizers. The integrated input common-mode buffer simplifies transformer or op-amp front-end design, while the LVDS DDR interface minimizes FPGA I/O pin count and eases multi-board synchronization.
The device is sampled on the rising edge of the clock and offers per-channel power dissipation in the low-200 mW range, supported by a 1.8 V supply. The 9 mm x 9 mm QFN-64 footprint with an exposed thermal pad enables reflow-compatible assembly and provides a low-junction-to-board thermal path for sustained full-rate dual-channel operation without external heatsinking. The pin suffix "HN" identifies the HVQFN 64-pin 9x9 mm body and "-C18" indicates the speed grade and output-mode ordering code.
Typical applications include multi-carrier wireless base-station receivers, radar and lidar digitizer front-ends, medical ultrasound beamformers, automated test equipment (ATE) and digital oscilloscope input stages, and multi-channel data-acquisition systems. In these roles the ADC1412D125HN-C18 is often paired with a low-jitter clock synthesizer, a differential input transformer or ADC driver amplifier, and an FPGA that deserializes the LVDS DDR data and performs downstream DSP.
When laying out the PCB, the exposed pad must be soldered to a continuous ground plane stitched with multiple thermal vias; this is the primary heat-dissipation path. Keep the analog input traces length-matched and 100 ohm differential, and isolate the 1.8 V AVDD/DRVDD planes with a ferrite bead to avoid digital switching noise coupling into the analog front-end.

Typische Anwendungen
ADC1412D125HN-C18 ist geeignet für 7 Anwendungs: Multi-Carrier Wireless Base Station Receiver, Radar / Lidar Digitizer Front-End, Medical Ultrasound Beamformer, Automated Test Equipment (ATE) and Instrumentation, Multi-Channel Data Acquisition (DAQ) Systems, Communications Test and Measurement, Software Defined Radio (SDR) Receiver.
Multi-Carrier Wireless Base Station Receiver
The ADC1412D125HN-C18 fits multi-carrier wireless base-station receivers because its dual 14-bit 125 MSPS cores deliver roughly 71 dBFS SNR and 85 dBc SFDR, which is enough spurious-free dynamic range to capture multiple LTE or 5G NR carriers without an analog downconversion chain. Each differential input is driven by a transformer-coupled front-end or an ADC driver like the ADA4937-1, and the LVDS DDR outputs land directly on a baseband FPGA. The 1.1 GHz analog input bandwidth lets the same ADC cover 3GPP bands up to several hundred MHz of instantaneous bandwidth, and the 1.8 V supply simplifies the power-tree design next to the RF transceiver.
Empfohlen
Radar / Lidar Digitizer Front-End
In radar and lidar digitizer front-ends the ADC1412D125HN-C18 is used to capture IF or baseband returns at 125 MSPS per channel with 14-bit resolution, sufficient for 70-80 dB of instantaneous dynamic range required by pulse-compression waveforms. The dual channels let the system digitize I and Q simultaneously from a single IF stage, eliminating quadrature-skew error that would otherwise degrade image rejection. The exposed thermal pad of the QFN-64 9x9 mm package removes the full-rate junction heat directly into the board ground pour, which is critical in sealed outdoor enclosures with limited airflow.
Empfohlen
Medical Ultrasound Beamformer
Beamforming in medical ultrasound arrays demands many simultaneously-sampling ADC channels at modest per-channel rates, and the ADC1412D125HN-C18's dual 14-bit 125 MSPS cores match that profile for 32- and 64-channel probe designs. The 14-bit resolution preserves the 70+ dB dynamic range required to resolve small lesions against background tissue, while LVDS DDR output minimizes the FPGA pin count across an entire probe-head PCB. The low 1.8 V supply and integrated input common-mode buffer simplify the per-channel analog front-end that would otherwise consume most of the probe-headboard area.
Empfohlen
Automated Test Equipment (ATE) and Instrumentation
ATE digitizers and benchtop instruments use the ADC1412D125HN-C18 to capture two channels at 125 MSPS in a compact 9x9 mm footprint, enabling multi-channel oscilloscope and signal-analyzer cards. The 14-bit resolution with 71 dBFS SNR provides enough vertical resolution to characterize 12- and 14-bit DUTs without losing effective bits, and the LVDS DDR interface lets the FPGA deserializer keep up at full rate. The exposed-pad QFN-64 package allows direct reflow onto a 4-layer ATE measurement card while keeping the analog front-end thermally isolated.
Empfohlen
Multi-Channel Data Acquisition (DAQ) Systems
Industrial and scientific multi-channel DAQ backplanes leverage the dual-channel density of the ADC1412D125HN-C18 to pack up to 16 channels per slot. The 125 MSPS per-channel rate covers vibration analysis, sonar hydrophone arrays, and particle-physics detector readouts where each channel needs synchronized 14-bit resolution. The QFN-64 9x9 mm package keeps the per-channel area under 25 mm^2, and the LVDS DDR outputs aggregate into an FPGA that timestamps and packetizes the samples before forwarding to the host processor.
Empfohlen
Communications Test and Measurement
Communications testers use the ADC1412D125HN-C18 to digitize modulated signals for vector signal analysis, where the 14-bit linearity and 85 dBc SFDR directly improve EVM measurements on 4G/5G waveforms. The dual channels let one ADC capture both the device-under-test and a reference signal simultaneously for differential error correction. Combined with a low-jitter clock such as an Si5341 and a high-linearity ADC driver, the ADC1412D125HN-C18 forms the analog front-end of a high-end modular wireless tester.
Empfohlen
Software Defined Radio (SDR) Receiver
Software defined radios benefit from the ADC1412D125HN-C18 because its dual 125 MSPS 14-bit cores support direct sampling of HF, VHF, and lower-UHF signals, offloading mixing and filtering to the FPGA. The 1.1 GHz input bandwidth means the same ADC can cover multiple amateur and commercial bands without changing the analog front-end, and the LVDS DDR output integrates cleanly with common SDR FPGA reference designs. A low-noise LDO such as the TPS7A4701 powers the analog rail, while a Si5351 clock generator provides the low-jitter sample clock needed to preserve SNR.

Designhinweise
Solder the exposed thermal pad (EPAD) of the ADC1412D125HN-C18 to a continuous analog ground plane with a 4x4 array of 0.3 mm thermal vias for heat removal. This is the primary thermal path at full-rate dual-channel operation; without it junction temperature can rise 20-30 C above ambient, degrading SNR. Keep the analog input traces 100 ohm differential, length-matched within 0.5 mm, and surrounded by a continuous ground-side reference plane to maintain the input return path.
Power the AVDD and DRVDD pins from separate 1.8 V LDO regulators (or a common LDO with a ferrite bead isolating the digital rail) to prevent digital switching noise from coupling into the analog front-end. Estimated: at 125 MSPS per channel the device dissipates roughly 400-500 mW total per the family datasheet; the 1.8 V AVDD current is on the order of 150-200 mA. Add 10 uF + 0.1 uF + 0.01 uF ceramic bypass capacitors within 2 mm of each AVDD/DRVDD pin.
Drive the CLK+/CLK- pins with a low-jitter differential source such as an Si5341 or an LVPECL fanout buffer; clock jitter above 300 fs rms directly degrades SNR. Keep the clock traces length-matched to within 1 mm and route them on a separate layer from the analog inputs. Avoid crossing clock traces with output data lines to prevent digital coupling into the clock path.
Do not let the LVDS output data lines exceed 2-3 cm before reaching a 100 ohm termination resistor; the ADC1412D125HN-C18's LVDS DDR edges are 1 ns wide and unterminated lines cause reflections. A common mistake is to leave the MODE pin floating; the pin must be tied high (LVDS) or low (CMOS DDR) with a 10 kohm pull-up/down to avoid indeterminate output behavior at power-up.
