HMCAD1040-80 Overview
What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage converter that processes the analog input through a cascade of low-resolution flash sub-ADC stages, each followed by a residue amplifier and DAC. This architecture delivers high sampling rates (tens to hundreds of MSPS) at moderate resolution (8-14 bits), occupying less silicon area than full-flash converters and consuming less power per MSPS. In the broader taxonomy: ADC -> data converter -> mixed-signal IC -> semiconductor. Pipelined ADCs dominate applications where conversion speed and channel density matter more than absolute DC precision.
Key features include 80 MSPS maximum sampling rate (the -80 suffix designates the 65/80 MSPS speed grade), 10-bit resolution across two simultaneous sampling channels, an internal bandgap reference, CMOS-compatible digital I/O, and a low-power operating profile suitable for portable and densely-populated designs. The pipelined core with proprietary calibration enables excellent linearity across the full operating range.
Technical depth: each channel contains a sample-and-hold front end, multi-bit pipelined quantizer, and on-chip digital error correction. A shared internal reference minimizes external component count and supports stable gain across temperature. The CMOS control interface allows direct connection to FPGAs, ASICs, or DSPs without level translation, while the parallel CMOS outputs deliver low-latency data ideal for high-throughput signal processing.
Typical applications include medical imaging (ultrasound beamformers, portable patient monitors), industrial inspection, communications IF/baseband digitizers, multi-channel data acquisition systems, and handheld test equipment. The dual-channel simultaneous-sampling nature makes it well-suited for I/Q demodulation and quadrature signal chains.
Design consideration: route analog inputs as differential pairs with controlled impedance, and place decoupling capacitors within 5 mm of the supply pins. The HVQCCN exposed pad must be soldered to the board ground plane for thermal and electrical performance.

Typical Applications
HMCAD1040-80 is suitable for 6 applications: Medical Ultrasound Imaging, Communications IF / Baseband Digitizer, Multi-Channel Data Acquisition Systems, Handheld Test & Measurement Equipment, Industrial Imaging & Inspection, Radar & Lidar Signal Processing.
Medical Ultrasound Imaging
The HMCAD1040-80's dual-channel simultaneous sampling at 80 MSPS makes it ideal for portable ultrasound beamformer front-ends. Each transducer element pair feeds two ADC channels with zero inter-channel skew, capturing the full I/Q or differential echo return without timing mismatch that would corrupt beamforming accuracy. The 10-bit resolution and pipelined architecture deliver adequate dynamic range for diagnostic imaging while the 64-LFCSP compact footprint supports high-channel-count probe designs. Industrial temperature grade (-40C to +85C) covers clinical and field-use environments. Pair with a low-noise LNA (e.g., AD8021) and FPGA-based beamformer (e.g., Xilinx Spartan-6) for a complete receive chain. Power consumption per channel is lower than legacy 12-bit ultrasound ADCs.
Recommended
Communications IF / Baseband Digitizer
The HMCAD1040-80's dual channels and 80 MSPS throughput enable direct digitization of intermediate-frequency (IF) signals in software-defined radio and base-station receivers. Place the ADC after a SAW filter and AGC stage; the dual simultaneous sampling captures I and Q paths from a quadrature demodulator without phase skew. The CMOS parallel output feeds directly into an FPGA or DSP for channelization and demodulation. The internal reference eliminates external reference noise susceptibility, while the 10-bit resolution is sufficient for many narrowband and broadband wireless standards. Lower power per channel than competing 12/14-bit parts extends battery life in portable test equipment.
Recommended
Multi-Channel Data Acquisition Systems
For industrial and scientific data acquisition, the HMCAD1040-80's dual-channel simultaneous sampling captures paired sensor outputs (e.g., strain gauges, thermocouples, vibration sensors) with matched timing. The pipelined architecture and 80 MSPS throughput support oversampling of slow signals to improve effective SNR beyond the 10-bit native resolution. CMOS parallel outputs enable direct connection to FPGAs for digital filtering and decimation. The compact 64-LFCSP package allows high channel density on a single PCB, critical for multi-channel vibration analysis or acoustic test arrays. Internal calibration maintains linearity across the industrial temperature range.
Recommended
Handheld Test & Measurement Equipment
The HMCAD1040-80's low power consumption per channel and small 64-LFCSP footprint make it ideal for portable oscilloscopes, logic analyzers with analog capture, and battery-powered spectrum analyzers. Dual simultaneous channels at 80 MSPS support two-channel handheld scopes in the entry-level segment. The CMOS parallel output minimizes interface complexity and BOM cost, while the industrial temperature range ensures operation in field environments. Internal reference and on-chip calibration reduce external component count, enabling smaller enclosure designs. Pair with a low-power FPGA and color LCD for a complete handheld scope platform.
Recommended
Industrial Imaging & Inspection
The HMCAD1040-80 suits machine vision and industrial inspection applications where two synchronized sensor channels need digitizing, such as stereo vision systems, line-scan camera pairs, or X-ray inspection detectors. Dual simultaneous sampling eliminates motion-induced skew between sensor pairs, critical for accurate depth measurement in stereo vision. The 80 MSPS rate supports high-speed line-scan cameras operating at thousands of lines per second after on-FPGA processing. Industrial temperature rating allows deployment in factory automation cells without thermal management overhead. The compact package fits space-constrained camera head electronics.
Recommended
Radar & Lidar Signal Processing
The HMCAD1040-80's dual 80 MSPS channels serve automotive and industrial radar/lidar receiver front-ends where two IF channels (I/Q or sum/difference) must be digitized simultaneously. The pipelined architecture handles pulsed-radar returns with fast settling, and the internal reference maintains gain stability across automotive temperature extremes (with derating). Low latency from input to digital output enables real-time DSP for obstacle detection. The compact 64-LFCSP package integrates into space-constrained sensor modules. For higher resolution requirements, consider the HMCAD1040 family alternatives or the 12-bit AD9226.

- Dual simultaneous sampling eliminates channel skew (vs Single-channel 10-bit ADCs)
Design Notes
Route analog input traces as matched-length differential pairs with 100 ohm differential impedance. Place the analog input decoupling capacitors (typically 10 nF and 100 nF in parallel) within 5 mm of the AVDD pins. Use a continuous ground plane on layer 2 directly beneath the analog traces to provide shielding and a low-impedance return path. The exposed pad (EP) must be soldered to the ground plane with multiple thermal vias (at least 9 vias in a 3x3 array) for electrical and thermal performance.
The CMOS parallel output data lines should be series-terminated with 33 ohm resistors close to the ADC to damp reflections on the transmission line to the FPGA. Keep output trace lengths matched (within 50 mil) to minimize skew between bits. Separate analog and digital sections of the board with a ground-plane split or moat, joined at a single point under the ADC's exposed pad, to prevent digital switching noise from coupling into the analog inputs.
Do not operate the HMCAD1040-80 without soldering the exposed pad to the ground plane - this degrades thermal performance and introduces ground bounce that corrupts ADC accuracy. Ensure the clock input has low jitter (< 5 ps RMS) to preserve SNR; a noisy clock source is the most common cause of unexpected ENOB degradation in pipelined ADCs. Verify the input common-mode voltage is within the ADC's specified range before applying signals.
Estimated: with both channels sampling at 80 MSPS and a 1.8V analog supply, the HMCAD1040-80 typically draws approximately 80-100 mW total per channel. Use low-dropout regulators (e.g., ADP7104) with pi-filter networks (ferrite bead + 10 uF + 100 nF) to isolate AVDD from digital supply noise. Power-down mode (PDN pin) reduces consumption to < 5 mW for battery-powered applications.
