ADC1415S105HN-C1 概要
An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples a continuous-time analog waveform and quantizes each sample into a discrete binary code at a specified sampling rate. Pipeline ADCs such as the ADC1415S105HN-C1 use a multi-stage architecture that converts one bit per stage while passing the residue to the next stage, achieving an efficient balance between sample rate, resolution, and die area. Within the broader mixed-signal taxonomy, this part belongs to the converter IC family under data acquisition, and it is specifically an intermediate-speed (>65 MSPS, ≤125 MSPS), single-channel, buffered pipeline ADC.
Key features include 14-bit resolution, a 105 MSPS maximum sampling rate, an integrated analog input buffer that relaxes external driving amplifier requirements, selectable CMOS or LVDS DDR output interfaces, and an operating temperature range suitable for industrial-grade designs. The part is described as part of a family that also includes 65, 80, and 125 MSPS speed grades, enabling pin-compatible scalability across performance points.
The architecture combines a wideband input buffer with a multi-stage pipelined core and an internal reference, which simplifies board-level design and reduces external component count. The HVQFN-40 exposed-pad package provides a low thermal resistance path for the 1.0 W (typical) dissipation at full sampling rate with CMOS outputs, enabling reliable operation on a 4-layer PCB with a modest copper pour.
Typical applications include medical imaging front-ends, multi-channel wireless base-station digitizers, radar and lidar intermediate-frequency sampling, industrial instrumentation, and high-speed data acquisition cards. The integrated buffer in particular makes the part attractive when designers want to avoid a high-bandwidth external ADC driver op-amp.
When designing with this part, treat the exposed pad as the primary thermal path and connect it to a ground plane with multiple thermal vias. For LVDS DDR mode, maintain 100-ohm differential routing and tightly match trace lengths to preserve timing margins at 105 MSPS.

主な用途
ADC1415S105HN-C1 の用途: 6 件s: Medical Imaging Front-End, Wireless Base-Station Digitizer, Radar and Lidar IF Sampling, High-Speed Data Acquisition Card, Industrial Test and Measurement Instrumentation, Software-Defined Radio (SDR) Front End.
Medical Imaging Front-End
The ADC1415S105HN-C1 suits medical imaging digitizer boards because its 14-bit resolution provides sufficient dynamic range for ultrasound and CT detector arrays, while the integrated input buffer simplifies the analog front end. The 105 MSPS sample rate comfortably handles IF-baseband digitization chains, and the HVQFN-40 package fits compact board layouts. Designers can pair it with low-noise ADCs such as the AD797 or the ADC1410S105HN-C1 (no-buffer variant) for system scaling. The dual CMOS/LVDS DDR output option aids in managing EMI in sensitive imaging environments.
おすすめ
Wireless Base-Station Digitizer
The ADC1415S105HN-C1 is well-suited to wireless base-station receive paths where intermediate-frequency signals must be digitized at sample rates above 80 MSPS. Its 14-bit resolution captures the dynamic range required for multi-carrier GSM/LTE signals, and the LVDS DDR output mode minimizes board-level EMI in densely packed multi-channel receivers. The integrated input buffer eliminates the need for an external high-bandwidth ADC driver on each channel, reducing BOM cost. The HVQFN-40 footprint enables compact card layouts typical of remote-radio-head (RRH) modules.
おすすめ
Radar and Lidar IF Sampling
In radar and lidar intermediate-frequency sampling subsystems, the ADC1415S105HN-C1 provides 14-bit resolution at 105 MSPS, enough to capture IF signals in automotive and industrial FMCW radar or pulsed lidar receivers. The integrated input buffer relaxes front-end amplifier selection, while LVDS DDR outputs allow timing-tight multi-board synchronization via matched differential pairs. The industrial -40 C to +85 C temperature range supports outdoor or vehicle-mounted installations. Designers commonly pair it with matched low-noise op-amps such as the ADA4898 or with an FPGA-based DSP stage on the back end.
おすすめ
High-Speed Data Acquisition Card
PCIe-based or USB-based data acquisition cards benefit from the ADC1415S105HN-C1's 14-bit, 105 MSPS performance for capturing transient signals, sonar hydrophone arrays, and vibration analysis channels. The CMOS output mode is often selected to simplify interface to an on-board FPGA, while LVDS DDR supports longer backplane traces in modular systems. The single-channel architecture suits applications where one high-speed channel is preferable to multi-channel slow ADCs, and the integrated input buffer simplifies analog front ends on density-constrained boards.
おすすめ
Industrial Test and Measurement Instrumentation
The ADC1415S105HN-C1's combination of 14-bit resolution, 105 MSPS sample rate, and integrated input buffer makes it a strong fit for industrial oscilloscopes, spectrum analyzers, and bench-top instrumentation. The LVDS DDR output mode supports high-throughput data transfer to a downstream DSP or FPGA for FFT computation. The HVQFN-40 exposed pad supports reliable operation over the industrial -40 C to +85 C range, important for test equipment used in uncontrolled factory environments. The part's four-member speed family (65/80/105/125 MSPS) lets manufacturers share PCB designs across product tiers.
おすすめ
Software-Defined Radio (SDR) Front End
Software-defined radio platforms benefit from the ADC1415S105HN-C1 as a direct-sampling front end for HF/VHF signals up to roughly 50 MHz of input bandwidth. The 105 MSPS sample rate supports comfortable Nyquist sampling or bandpass sampling of intermediate-frequency signals in transceiver chains. The LVDS DDR output mode pairs naturally with FPGA-based DSP such as the XC7A35T for software-defined demodulation. The integrated input buffer eliminates the need for a separate wideband ADC driver, simplifying the RF chain and reducing overall noise figure contribution.

設計ノート
The HVQFN-40 package exposes its thermal pad (pin 40) on the bottom side; this MUST be soldered to a continuous PCB ground plane with multiple thermal vias (typically 9 vias in a 3x3 array under the pad). Estimated: at 105 MSPS with CMOS outputs, dissipation is approximately 1.0 W (datasheet typical); without thermal vias and copper pour, the die can exceed its 125 C junction limit in still-air environments. Maintain at least 1 oz copper with a 1 square inch ground pour on at least the top layer for reliable operation.
For LVDS DDR output mode, route each 100-ohm differential pair with matched lengths (within 5 mils) and maintain continuous reference-plane return paths. Place decoupling capacitors (100 nF + 10 uF bulk) within 2 mm of each VDD and OVDD pin. Estimated: keeper traces length-matched to within 150 ps keeps DDR timing margins robust at 105 MSPS. Keep the analog input traces short, and surround analog and clock traces with a ground pour to avoid digital coupling.
Sequence analog VDD before OVDD during power-up to avoid latch-up; the integrated PD (power-down, pin 30) and RESET (pin 31) allow software-controlled startup. Estimated: a 10 ms delay between AVDD and OVDD rails (achieved via RC delay or sequencer IC) is sufficient for the ADC1415S105HN-C1 to come up cleanly. Use a low-noise LDO such as the ADP1755 for AVDD to keep supply-induced noise out of the analog input path.
