Analog Devices introduces a high performance data acquisition solution that eases engineering challenges for precision applications, evaluation board and samples available from Anglia

Analog Devices ADAQ4003


Analog Devices have introduced the ADAQ4003 μModule® precision data acquisition (DAQ), signal chain solution that reduces the development cycle of precision measurement systems by transferring the signal chain design challenge of component selection, optimization, and layout from the designer to the device.

System and circuit-level hardware designers can spend significant research and development (R&D) resources and time to develop high performance, discrete linear, and precision signal chain blocks for their end applications, however the electronic industry’s dynamics are rapidly evolving meaning there is now less time to build and prototype analog circuits to verify their functionality and on top of this tight control of R&D budgets and the need to reduce time to market mean meeting these constraints is getting ever more challenging. Today’s hardware designers are now demanding advanced precision data conversion performance and increased robustness for complex designs in an ever-shrinking form factor amid thermal and PCB density limitations. The ADAQ4003 precision data acquisition module from Analog Devices has been developed to address all of these tough challenges with a solution that combines their signal chain know-how and years of experience into a compact integrated device.

Using system-in-package (SIP) technology, the ADAQ4003 reduces end system component count and complexity by combining multiple common signal processing and conditioning blocks into a single device. These blocks include a high resolution 18-bit, 2 MSPS successive approximation register (SAR), analog-to-digital converter (ADC), a low noise, fully differential ADC driver amplifier (FDA), and a stable reference buffer.

The ADAQ4003 signal chain solution is housed in a small, 7 mm × 7 mm, 0.80 mm pitch, 49-ball CSP_BGA enabling compact form factor designs without sacrificing performance and at the same time simplifying end system bill of materials management. This level of system integration makes the ADAQ4003 much less sensitive to printed circuit board layout while still providing flexibility to adapt to a wide range of signal levels. The specified temperature range for the ADAQ4003 is from −40°C to +125°C.
