IDTADC1210S080HN-C1 Overview
An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts a continuous-time analog voltage on its input pin into a discrete digital code at its output. It belongs to the data converter (ADC/DAC) product family within data acquisition ICs, which sit in the broader mixed-signal and signal-chain hierarchy. Pipelined ADCs like the ADC1210S series use a multi-stage architecture with per-stage flash sub-ADCs and digital error correction, achieving a balance of high sampling rate, moderate resolution (10-14 bits), and low power consumption per MSPS.
Key specifications include 12-bit native resolution, 80 MSPS maximum sampling rate, support for both single-ended CMOS and differential LVDS DDR output modes, and a pipelined architecture with a typical latency of several clock cycles. The part is offered in a 40-pin HVQFN package (6x6 mm body) with an exposed thermal pad for low thermal resistance.
The ADC1210S series shares a common silicon platform across 65/80/105/125 MSPS speed grades, allowing engineers to scale sampling rate on the same PCB footprint. The differential LVDS DDR mode delivers data on both clock edges, halving the per-pin output rate and easing FPGA/CPLD capture at 80 MSPS and beyond, while the CMOS mode simplifies low-cost MCU or DSP interfacing at slower rates.
Typical applications include communications IF basestats, ultrasound imaging receivers, portable test and measurement instrumentation, radar signal processing front ends, and medical imaging data acquisition cards. The wide input common-mode support and internal reference simplify board design in space-constrained applications.
When designing with this device, allocate a solid ground plane beneath the package and bond the exposed pad to analog ground. Decouple VDDA with a 1 uF plus 10 nF ceramic pair close to the pin, and keep the analog input trace short and impedance-controlled (typically 50 ohm or 75 ohm terminated) to preserve ENOB at high input frequencies.

Typical Applications
IDTADC1210S080HN-C1 is suitable for 6 applications: Communications IF Baseband Receiver, Ultrasound Imaging Receiver, Portable Test and Measurement Instrumentation, Radar Signal Processing Front End, Medical Imaging Data Acquisition Card, Industrial Process Control and Data Logging.
Communications IF Baseband Receiver
The IDTADC1210S080HN-C1's 80 MSPS sampling rate and 12-bit resolution make it well-suited for IF (intermediate frequency) baseband signal acquisition in software-defined radio and wireless base station receivers. The LVDS DDR digital output mode delivers data on both clock edges, halving the per-pin output rate to 400 Mbps and easing FPGA capture at high sample rates. The differential analog input supports the typical 1 V peak-to-peak IF signal levels used in quadrature demodulators, while the pipelined architecture provides the several-clock-cycle latency acceptable for block-based DSP processing. Compared with a 14 or 16-bit ADC, the 12-bit resolution is sufficient for many cellular and WiFi IF chains where the dynamic range budget is dominated by the front-end LNA and mixer, not the digitizer.
Recommended
Ultrasound Imaging Receiver
The IDTADC1210S080HN-C1 targets medical ultrasound receiver arrays where each channel digitizes a conditioned echo signal. Its 80 MSPS sampling rate captures the full bandwidth of pre-beamformed RF ultrasound signals up to approximately 35 MHz Nyquist, while the 12-bit resolution is sufficient for typical 60-70 dB dynamic range imaging systems. The 40-pin HVQFN package with exposed thermal pad enables compact multi-channel board designs where many ADCs are placed in a dense array behind the transducer. The CMOS output mode simplifies direct interfacing to FPGAs that perform beamforming and envelope detection, while the LVDS DDR mode supports longer PCB trace runs to a central processing FPGA. Compared to higher-speed ADCs, the 80 MSPS rate keeps power consumption manageable in portable cart designs.
Recommended
Portable Test and Measurement Instrumentation
The IDTADC1210S080HN-C1 fits portable oscilloscope and spectrum analyzer front-end digitizers where 80 MSPS and 12-bit resolution are sufficient for moderate-bandwidth measurement applications. The pipelined ADC architecture provides the consistent latency required for accurate triggering, while the selectable CMOS or LVDS DDR outputs allow designers to trade output bus simplicity (CMOS) for high-speed signal integrity (LVDS) based on PCB layout. The 3.0 V analog and 1.8 V digital supplies are easily derived from common USB-powered or battery-powered rails. Compared with 8 or 10-bit oscilloscope ADCs, the 12-bit resolution provides 4-8 dB additional dynamic range for cleaner FFT-based spectrum displays in handheld test equipment.
Recommended
Radar Signal Processing Front End
The IDTADC1210S080HN-C1 serves as the digitizer for short-range radar front ends in industrial and automotive pre-development applications. Its 80 MSPS sampling rate supports IF bandwidths up to approximately 35 MHz, sufficient for short-range FMCW radar chirp demodulation. The 12-bit resolution provides adequate dynamic range for target detection at moderate ranges where strong returns from clutter would saturate a 10-bit ADC. The LVDS DDR output mode enables placement of the ADC near the antenna with a serialized digital link back to the processor FPGA, reducing analog trace length and noise pickup. The wide -40 C to +85 C operating temperature range covers industrial radar deployments in factory automation and outdoor security systems.
Recommended
Medical Imaging Data Acquisition Card
The IDTADC1210S080HN-C1 functions in medical imaging data acquisition cards for modalities like optical coherence tomography (OCT) and confocal microscopy. Its 80 MSPS sampling rate captures the digitized interferometric signal at sufficient bandwidth for moderate-depth imaging, while the 12-bit resolution supports the 60-72 dB dynamic range typical of clinical imaging systems. The pipelined latency is acceptable for block-based image reconstruction algorithms. The 40-pin HVQFN package and 3.0 V/1.8 V dual supplies simplify integration into PCI-Express or USB-3 acquisition cards where board real estate is constrained. Compared with audio-bandwidth ADCs, the 80 MSPS rate provides the oversampling needed for anti-alias filtering and noise reduction in sensitive medical measurements.
Recommended
Industrial Process Control and Data Logging
The IDTADC1210S080HN-C1 supports industrial process control and high-speed data logging applications where multiple sensor channels must be sampled simultaneously at moderate rates. Its single-channel 80 MSPS capability multiplexes to support vibration analysis, acoustic emission monitoring, and high-speed transducer readout in factory automation systems. The selectable CMOS output mode simplifies direct connection to industrial microcontrollers or DSPs without requiring an FPGA. The -40 C to +85 C industrial temperature range covers factory floor environments. Compared with 16 or 24-bit precision ADCs, the 12-bit resolution is a deliberate trade-off for bandwidth and latency in time-critical control loops, where oversampling and digital filtering would add unacceptable group delay.

Design Notes
The IDTADC1210S080HN-C1 requires a clean 3.0 V analog supply (VDDA) and a 1.8 V digital supply (VDDO). Place a 1 uF X7R ceramic plus a 10 nF NP0 ceramic decoupling pair within 2 mm of each VDDA and VDDO pin. Use a ferrite bead or small LC filter between the analog and digital 3 V/1.8 V rails to prevent digital switching noise from coupling back into the analog front end. Estimated: at 80 MSPS with CMOS output mode, the part draws approximately 100-150 mW; budget LDOs with at least 200 mA capacity on each rail to handle inrush during power-up.
Allocate a continuous analog ground plane on the top layer directly under the 40-pin HVQFN package, and bond the exposed thermal pad (EP) to this ground with at least 9 thermal vias in a 3x3 array for low thermal resistance. Route the differential analog input traces as a 100 ohm differential pair (or 50 ohm single-ended terminated) on the top layer over a continuous ground reference; avoid crossing these traces with digital output lines. Keep the LVDS DDR output traces length-matched within 1 mm to preserve data-eye margin at 80 MSPS.
Do not leave the exposed thermal pad floating - it must be soldered to the analog ground plane for both electrical reference and thermal dissipation. Ensure the analog input common-mode voltage is within the datasheet-specified VCM range (specific value [DATA_NEEDED: VCM range] not provided in web data); violating this range degrades ENOB and may damage the input ESD cells. When using LVDS DDR output mode, terminate the differential pairs with a 100 ohm resistor at the receiver (FPGA), not at the ADC end, to avoid reflections. The clock input should be AC-coupled or DC-coupled per datasheet guidance, with a clean low-jitter source - estimated jitter budget below 1 ps RMS for full ENOB performance.
