ADC1412D105HN-C1 Présentation
A pipelined ADC is a high-speed successive-approximation-style converter that splits the conversion into multiple low-resolution stages with a digital error-correction backend, achieving sample rates in the tens-to-hundreds of MSPS while keeping power dissipation modest. In the broader taxonomy it sits under ADC -> data converter -> signal-chain IC -> mixed-signal semiconductor. Pipelined ADCs are the workhorse of IF/RF digitisation, communications baseband, medical imaging front-ends, and general-purpose high-speed instrumentation because they balance speed, resolution, and channel density better than SAR or flash converters.
Key features of the ADC1412D105HN-C1 include a maximum sample rate of 105 MSPS, 14-bit resolution across two matched channels, programmable CMOS or LVDS DDR output formats, an integrated input common-mode buffer with adjustable input range, and per-channel power-down control. The device also exposes an SPI-compatible serial configuration port for output format, gain, offset, and channel calibration, and is designed to interoperate cleanly with downstream FPGAs and DSPs in parallel or serial capture modes.
Architecturally, the converter uses a multi-stage pipeline with proprietary digital error correction and on-chip calibration logic that reduces the dependence on laser trimming and improves SFDR/INL stability across temperature. The LVDS DDR output mode reduces board-level pin count and switching noise by halving the parallel bus width per sample, while the CMOS mode offers direct compatibility with low-cost ASICs and microcontrollers.
Typical applications include wireless communications baseband digitisation, multi-channel data acquisition systems, medical ultrasound front-ends, portable and bench-top test/measurement instruments, and dual-antenna or diversity receiver IF sampling. Designers also use this ADC in software-defined radio (SDR) and radar signal chains where dual matched channels simplify I/Q digitisation.
When designing with this ADC1412D105HN-C1, ensure the input common-mode voltage and swing are within the supported range, use a low-jitter clock to avoid SNR degradation, and follow the datasheet reference layout for the HVQFN exposed pad to keep the die within thermal limits at full duplex 105 MSPS operation. The part is footprint-compatible with the wider ADC1412D family at 65/80/105/125 MSPS rates, simplifying one-BOM multi-product designs.

Applications typiques
ADC1412D105HN-C1 convient pour 6 applications: Wireless Communications Baseband Digitisation, Multi-Channel Data Acquisition Systems, Medical Ultrasound Front-End, Software-Defined Radio (SDR) and IF Sampling, Portable Test and Measurement Instruments, Radar and Lidar Receiver Signal Chains.
Wireless Communications Baseband Digitisation
The ADC1412D105HN-C1's dual 14-bit 105 MSPS channels simplify I/Q digitisation in wireless baseband receivers by capturing both the in-phase and quadrature paths with matched latency. With LVDS DDR outputs the bus switches half as often per sample, easing FPGA pin-count pressure. Placed after the IF mixer and anti-alias filter, the part provides the dynamic range needed for adjacent-channel rejection while keeping the bill of materials low by replacing two single-channel ADCs with one dual-channel device.
Recommandé
Multi-Channel Data Acquisition Systems
In modular data-acquisition cards the ADC1412D105HN-C1 packs two 105 MSPS, 14-bit channels into a single 64-pin HVQFN footprint, doubling channel density per square centimetre versus two discrete ADCs. The SPI configuration port allows per-board gain and offset calibration without external DACs. Designers typically place the part adjacent to a low-jitter clock generator and a fully differential driver to preserve SNR, then route the LVDS DDR outputs to a downstream FPGA for storage or DSP.
Recommandé
Medical Ultrasound Front-End
Ultrasound beamformers require dozens of matched, simultaneously-sampling ADCs with low noise and good spurious-free dynamic range. The ADC1412D105HN-C1 delivers 14-bit resolution across two channels per IC, reducing the front-end board area and per-channel power compared with discrete single-channel ADC arrays. The LVDS DDR digital interface cleanly drives downstream FPGAs that perform digital beamforming, and the industrial temperature range supports the chassis environments of cart-based ultrasound systems.
Recommandé
Software-Defined Radio (SDR) and IF Sampling
Wide-band SDR platforms benefit from the 14-bit resolution and 105 MSPS sample rate of the ADC1412D105HN-C1 because both I and Q baseband signals can be digitised with matched gain, offset, and skew. The CMOS or LVDS DDR output flexibility lets the designer choose between a low-cost microcontroller capture path or a high-speed FPGA signal-processing chain. When the IF carrier exceeds 50 MHz, designers can move to the 125 MSPS sibling in the same footprint without PCB rework.
Recommandé
Portable Test and Measurement Instruments
Handheld oscilloscopes and spectrum analysers need high dynamic range at low power. The ADC1412D105HN-C1 supports per-channel power-down via the SPI control interface, so unused channels can be turned off to extend battery life. The 14-bit resolution combined with 105 MSPS sample rate is sufficient for 25 MHz class bandwidth oscilloscope front-ends, and the LVDS DDR outputs reduce the FPGA pin count and PCB routing complexity in compact enclosures.
Recommandé
Radar and Lidar Receiver Signal Chains
Differential I/Q sampling at the output of radar or lidar mixers demands matched channels with low inter-channel skew. The ADC1412D105HN-C1 delivers two simultaneously sampling 14-bit channels at 105 MSPS, preserving the amplitude and phase relationship needed for coherent detection. Designers pair the ADC with a low-noise LDO such as TPS7A4701 to supply the analog rails and with an FPGA such as XC7A25T-1CPG238I to perform real-time pulse compression or FFT.

Principaux différenciateurs
- Dual matched 14-bit 105 MSPS channels in a single HVQFN-64 package (vs ADC1410S105HN-C1)
- Footprint-compatible with the wider 65/80/105/125 MSPS ADC1412D family (vs ADC1412D125HN-C1)
- Programmable CMOS or LVDS DDR digital outputs (vs ADC1012D080HN/C1:5)
Notes de conception
The HVQFN-64 9x9 mm exposed pad is the primary thermal and ground path; failing to solder it to a continuous, low-impedance ground plane can degrade SNR by 3-5 dB and cause channel-to-channel skew drift. Use at least 9 thermal vias in the pad area to inner ground layers, following the manufacturer reference layout.
Clock jitter directly converts to aperture-jitter-limited SNR: SNR_max = 20*log10(1 / (2*pi*Fin* tj)). At Fin = 70 MHz and a typical 200 fs tj, expect an SNR ceiling near 70 dB. Drive CLKP/CLKN with a low-jitter LVDS or LVPECL source; do NOT use an LVCMOS clock if the input analog frequency exceeds 30 MHz.
Decouple VA1A, VA1B, VA2 close to the device pins with 100 nF X7R in parallel with 10 uF ceramic, and place a ferrite bead between the analog and digital supplies to suppress switching noise from the LVDS DDR outputs. Power-down unused channels via PDN_A / PDN_B through the SPI interface to save roughly 30% of total power in single-channel operation.
Route the LVDS DDR data outputs with 100 ohm differential impedance and length-match pairs within 2 mm to avoid skew that could corrupt the FPGA capture FIFO. Keep analog input traces (INA+/-, INB+/-) symmetric and guarded by ground pours; do not cross analog and digital traces to prevent coupling of CMOS switching noise into the analog front-end.
Estimated: at 105 MSPS dual-channel operation and 1.8 V analog supply, the device dissipates approximately 0.5-0.7 W. With theta_JA near 25 C/W on a 4-layer JEDEC board, junction temperature rise is ~12-17 C above ambient - well within the 125 C industrial limit. For fan-less sealed enclosures, derate by 20% or drop to ADC1412D080HN-C1 (80 MSPS) to extend margin.
