HMCAD1040-40 概要
An ADC (analog-to-digital converter) is a data-acquisition component that converts continuous analog signals into discrete digital codes. Within the signal chain hierarchy, an ADC sits between the analog front end (sensor, amplifier, anti-alias filter) and the digital back end (DSP, FPGA, processor). Pipelined ADCs like the HMCAD1040-40 use a multi-stage architecture to achieve high sample rates at low power, making them well suited to multi-channel applications where energy and board area are constrained.
Key features include 10-bit resolution, 61.6 dB SNR at 8 MHz input, internal reference circuitry (eliminating the need for an external reference IC), a 1.8 V core supply, a 1.7-3.6 V I/O supply for direct interfacing to modern CMOS logic, parallel CMOS output data, and a serial CMOS control interface. The proprietary internal structure balances dynamic performance with very low power consumption across the 20/40 MSPS operating range.
In dual-channel mode the ADC can convert two independent analog inputs simultaneously, doubling channel density per package. The CMOS control interface allows configuration of channel selection, sample rate, and output formatting through a simple serial bus, while the parallel CMOS outputs integrate directly with ASICs, FPGAs, or microcontrollers without level translation.
Typical applications include portable instrumentation, handheld oscilloscope front ends, low-power medical imaging, IF sampling in communication receivers, and industrial multi-channel data acquisition. The combination of dual channels, 40 MSPS capability, and 43 mW power dissipation makes the part attractive for battery-powered and channel-dense designs.
When designing with this device, place the decoupling capacitors as close as possible to the analog and digital supply pins and keep the analog input traces short and guarded to preserve SNR. The internal reference is adequate for most applications, but a low-noise external reference may improve SFDR in the most demanding spectra.

主な用途
HMCAD1040-40 の用途: 6 件s: Portable Instrumentation, Handheld Oscilloscope Front End, Low-Power Medical Imaging, IF Sampling in Communication Receivers, Industrial Multi-Channel Data Acquisition, Ultrasound Beamformer Sub-Array.
Portable Instrumentation
The HMCAD1040-40 fits portable, battery-powered instrumentation front ends where dual channels and low power dissipation are critical. Its 43 mW power at 40 MSPS and dual-input architecture let a handheld oscilloscope or data logger digitize two signals simultaneously without exceeding the thermal envelope of a small plastic enclosure. The internal reference removes the cost and board area of an external reference IC, which matters in compact, cost-sensitive portable designs where every square millimeter of PCB is reserved for sensors, batteries, or user I/O.
おすすめ
Handheld Oscilloscope Front End
The HMCAD1040-40's 40 MSPS sample rate and dual channels support a two-channel handheld DSO front end, digitizing both CH1 and CH2 simultaneously with 10-bit vertical resolution. The 61.6 dB SNR at 8 MHz input keeps visible noise low on the display, while the parallel CMOS outputs feed directly into an FPGA or microcontroller for triggering and waveform rendering. The 43 mW dissipation at full speed keeps the handheld's battery budget manageable during extended field measurements.
おすすめ
Low-Power Medical Imaging
Ultrasound and other low-power medical imaging front ends require simultaneous multi-channel digitization at modest sample rates. The HMCAD1040-40 dual 10-bit 40 MSPS channels serve as a building block for compact probe modules where channel density and low heat dissipation are paramount. Its internal reference and 1.8 V core supply simplify the safety-isolation design, while the CMOS outputs drive an FPGA-based beamformer or DSP without level translation.
おすすめ
IF Sampling in Communication Receivers
The HMCAD1040-40 suits narrow-band IF sampling in low-cost communication receivers such as software-defined radio (SDR) and PMR base stations. Its 40 MSPS rate comfortably digitizes IF signals up to about 18 MHz with 10-bit resolution, while 61.6 dB SNR preserves modulation fidelity. The dual channels support diversity or I/Q baseband digitization, and the 1.7-3.6 V I/O supply allows direct interface to 3.3 V DSP or baseband processors.
おすすめ
Industrial Multi-Channel Data Acquisition
Multi-channel industrial data-acquisition systems - such as vibration analyzers, process controllers, and condition-monitoring modules - benefit from the HMCAD1040-40's dual-channel density. Two ADCs per package reduce part count on the analog input board, lowering BOM cost and improving mean time between failures. The industrial temperature grade and 24/43 mW dissipation simplify cooling in DIN-rail or sealed enclosures with limited airflow.
おすすめ
Ultrasound Beamformer Sub-Array
Within a portable ultrasound beamformer, the HMCAD1040-40 handles sub-array receive digitization with two channels per IC. The combination of dual inputs, 40 MSPS rate, and 43 mW power keeps the per-channel thermal budget within the patient-isolation enclosure limits. The parallel CMOS outputs feed directly into a beamforming FPGA, eliminating serializer latency and simplifying the timing closure for high-channel-count probe heads.

設計ノート
Provide a clean, low-noise 1.8 V analog supply (AVDD) with at least 10 uF bulk plus 0.1 uF and 10 nF decoupling placed within 5 mm of each AVDD pin. The 1.7-3.6 V DVDD supply should be derived from a separate LDO from the system 3.3 V rail to prevent digital switching noise from coupling into the analog input and degrading the 61.6 dB SNR. Estimated: at 43 mW dissipation and theta-JA of approximately 28 C/W (typical 64-QFN 9x9 mm), the junction temperature rise is only ~1.2 C above ambient - no heatsink is required.
Route analog inputs as 50 ohm controlled-impedance differential pairs and keep them short and guarded by ground pour on both sides. Place the analog input RC anti-alias filter within 10 mm of the ADC input pins. The exposed thermal pad must be soldered to a continuous ground plane with at least 9 thermal vias to the inner ground layers for low-impedance grounding and heat spreading. Do not route digital output traces under the analog input section.
Common pitfalls include: (1) using a single shared LDO for AVDD and DVDD, which injects digital switching noise into the analog front end; (2) omitting the input common-mode bias, which can push the input outside the linear range; (3) failing to terminate the analog input differentially, causing reflections and degraded SNR; (4) driving the parallel CMOS outputs into an unterminated bus, leading to overshoot/undershoot. Always consult the manufacturer's reference design and follow the layout guidelines in the datasheet.
