IDTADC1010S105HN-C1 Overview
What is a pipelined ADC? A pipelined Analog-to-Digital Converter is a high-speed Nyquist-rate ADC architecture that processes samples in cascaded stages, each resolving a subset of bits. Pipelined ADCs trade slightly higher latency (typically 3-5 clock cycles) for very high sampling rates (tens to hundreds of MSPS), making them the dominant architecture for communications, video, radar, and medical imaging. Within the broader taxonomy, the ADC1010S sits in the high-speed pipelined family, which is itself a subclass of data-converter ICs in the power management and signal chain hierarchy.
Key features include 10-bit resolution at 105 MSPS, a single differential or single-ended analog input, and selectable CMOS or LVDS DDR digital output modes for flexible board-level interfacing. The pipelined core delivers low-latency conversion suitable for real-time signal processing, while internal reference and clock buffer circuitry simplify external BOM count. Typical performance figures cited in the IDT datasheet Rev. 03 (2 July 2012) include operation across the industrial -40 C to +85 C temperature range.
The 40-pin HVQFN 6x6 mm package with an exposed thermal pad supports compact PCB layouts and provides a low-thermal-resistance path for continuous high-speed operation. Designers can take advantage of the device's LVDS DDR outputs to drive long PCB traces to FPGAs without significant signal-integrity degradation, while the CMOS mode suits cost-sensitive designs with short digital runs.
Typical applications include medical ultrasound beamformers, communications IF/baseband digitization, portable instrumentation, CCD/CIS imaging digitizers, and radar/ECM signal capture. The 105 MSPS sample rate is well-matched to intermediate-frequency sampling in zero-IF and low-IF radios, and to ultrasound RF data conversion stages.
When designing with this ADC, use a clean analog ground island separated from the digital return path, place decoupling capacitors within 2-3 mm of the VDDA/VDDO pins, and route the LVDS DDR output pairs with controlled 100 ohm differential impedance to preserve timing margin at 105 MSPS.

Typical Applications
IDTADC1010S105HN-C1 is suitable for 6 applications: Medical Ultrasound Beamformers, Communications IF/Baseband Digitization, Portable Instrumentation and Data Acquisition, CCD and CIS Image Sensor Digitization, Radar and ECM Signal Capture, Industrial Process Control and Motor Drive Sensing.
Medical Ultrasound Beamformers
The IDTADC1010S105HN-C1's 105 MSPS sample rate and 10-bit resolution are well-matched to medical ultrasound analog front ends where transducer RF echoes are digitized for beamforming and harmonic imaging. The pipelined architecture provides consistent low-latency conversion needed for real-time delay-and-sum processing. The 40-HVQFN package with exposed pad supports the dense multi-channel board layouts typical of portable ultrasound carts. LVDS DDR outputs cleanly drive FPGA beamforming chips over long PCB traces, preserving timing margin. For higher channel count designs the dual-channel ADC1213S125HN-C1 in the same family offers channel count scalability at 125 MSPS.
Recommended
Communications IF/Baseband Digitization
The IDTADC1010S105HN-C1 is widely deployed in the IF and baseband sections of wireless infrastructure and software-defined radio (SDR) where a single-channel, mid-speed high-performance ADC is required. Sampling at 105 MSPS comfortably handles IF signals in the 20-40 MHz range with the Nyquist margin needed for digital downconversion in the FPGA. The LVDS DDR output mode preserves signal integrity to a remote FPGA, while separate VDDA=3V and VDDO=1.8V rails support clean integration with 65 nm and 28 nm FPGA families. Designers can pair this ADC with the ADC1613S125HN-C1 (in the Site MPN list) for higher-rate LTE/5G applications.
Recommended
Portable Instrumentation and Data Acquisition
The IDTADC1010S105HN-C1 fits portable benchtop and field instrumentation where 10-bit resolution, 105 MSPS speed, and low power are required. Its small 40-HVQFN 6x6 mm footprint and 1.8 V digital I/O simplify integration with low-power FPGAs such as Cyclone or Lattice ECP5 used in handheld oscilloscope probes, vibration analyzers, and spectrum analyzers. The industrial -40 C to +85 C operating range supports outdoor and industrial deployments. The 3 V analog supply allows direct connection to op-amp based signal conditioning without level shifting. Use the lower-rate ADC1010S080HN/C1:5 for cost-sensitive applications not requiring 105 MSPS performance.
Recommended
CCD and CIS Image Sensor Digitization
The IDTADC1010S105HN-C1 serves as the analog front-end digitizer in CCD and CIS image sensor applications, where pixel-rate analog signals are buffered and digitized before digital image processing. The 105 MSPS sample rate matches high-resolution industrial line-scan cameras and medical imaging sensors with pixel rates up to 100 MHz. Single-channel operation simplifies per-channel synchronization, and the 10-bit resolution is sufficient for many industrial machine-vision and document-scanning tasks. The exposed-pad HVQFN package allows tight stacking with the image sensor on the same PCB. For higher-precision imaging, the 12-bit ADC1213S080HN-C18 (in the Site MPN list) provides an upgrade path.
Recommended
Radar and ECM Signal Capture
The IDTADC1010S105HN-C1 suits defense and aerospace signal-capture applications such as radar IF digitizers, electronic-countermeasures (ECM) receivers, and EW (Electronic Warfare) jammers where single-channel high-speed conversion is required. The 105 MSPS sample rate handles the IF bandwidths typical of ground-based radar systems, while the industrial temperature range supports harsh environmental operation. The LVDS DDR digital output is a natural fit for FPGA-based digital downconversion and pulse-compression processing. For high-frequency radar front ends, the higher-bandwidth ADC1610S125HN-C1 (in the Site MPN list) provides a 125 MSPS drop-in alternative.
Recommended
Industrial Process Control and Motor Drive Sensing
The IDTADC1010S105HN-C1 is used in industrial process control and motor drive systems to digitize high-speed current/voltage feedback signals for digital control loops. The 105 MSPS rate comfortably oversamples switching-frequency content in high-power motor drives, enabling high-bandwidth digital current control and fault detection. Single-ended input mode simplifies direct connection to Hall-effect current sensors and shunt amplifiers. The 40-HVQFN 6x6 mm package and extended temperature range fit industrial embedded designs. For multi-axis motor drives, the dual-channel ADC1012D080HN/C1:5 in the same package family allows two-axes-per-chip integration.

- Dual-output format support (CMOS and LVDS DDR) (vs ADCs with single-format outputs)
Design Notes
Provide separate analog (VDDA=3V) and digital (VDDO=1.8V) rails generated from a low-noise LDO such as a TPS7A47xx from each intermediate bus. Place 10 uF tantalum and 0.1 uF ceramic decoupling capacitors within 2-3 mm of each VDDA/VDDO pin, with the ceramic cap closest. Add a ferrite bead between the analog LDO and the VDDA pin to attenuate switching noise from digital circuits. The datasheet Rev. 03 specifies typical power at VDDA=3V, VDDO=1.8V, Tamb=25 C, so worst-case (85 C) dissipation can be 10-15% higher - derate accordingly.
The 40-HVQFN package requires a continuous ground plane on the top layer stitched to lower ground layers with 0.3 mm vias. Route CLK+/CLK- as a 100 ohm differential pair with matched length, and route the 10-bit CMOS or LVDS DDR data bus as a matched group (within 50 ps skew). Keep analog input traces short and guarded by ground on both sides to reduce coupling from the 105 MSPS digital switching. The exposed thermal pad MUST be soldered to a 4x4 mm minimum copper pour to provide a 25-30 C/W thermal path.
For LVDS DDR output mode, use 100 ohm differential-impedance traces and add a 100 ohm termination resistor at the FPGA receiver. The 10-bit data plus DCLK forms 11 critical nets, all to be length-matched within 1-2 mm. Enable the duty-cycle stabilizer (DCS pin) at sample rates above 65 MSPS to maintain 50% clock duty cycle. Drive the CLK+/CLK- input with a low-jitter clock source (jitter < 1 ps RMS) to avoid degrading SNR; SNR is approximately SNR = 6.02N + 1.76 dB + 10*log10(Fs/2*FIN) for an ideal N-bit ADC.
