ADI ADAQ4003 micromodule DAQ, SiP provided
Low-noise fully differential ADC and reference buffer combination
Accelerate the development of precision measurement systems by reducing signal chain design.


Mouser Electronics, Inc., the authorized global distributor with the newest semiconductors and electronic components, is now stocking the ADAQ4003 micromodule (µModule®) data acquisition (DAQ) solution from Analog Devices (ADI). The system-in-package (SiP) design of the ADAQ4003 eliminates signal-chain design challenges like component selection, optimization, and arrangement, accelerating the development cycle of precision measurement systems.

The ADAQ4003 combines a low-noise, fully differential analog-to-digital converter (ADC) driver, a stable reference buffer, and a high-speed 18-bit, 2-MSPS successive approximation register (SAR) ADC. It also integrates ADI's iPassives® technology, providing passive components with matching and drift characteristics that minimize error sources over temperature.

Available in a 7 × 7mm BGA package, it saves 75% of the footprint compared to comparable solutions comprised of multiple components, enabling the use of small form factor instruments without compromising performance. The SPI-compatible serial user interface is compatible with 1.8V, 2.5V, 3V, and 5V logic using a separate digital interface voltage (VIO) supply.

By integrating several common signal processing and conditioning blocks into a single device, the ADAQ4003 reduces the number of components in the end system along with the development cycle time for systems such as automatic test equipment, equipment automation, process control, medical devices, and digital control loops.
