In stock now at distributor Mouser Electronics is the ADAQ4003 µModule data acquisition solution (DAQ) from Analog Devices.

Utilising system-in-package (SIP) technology, the ADAQ4003 reduces the development cycle of a precision measurement system by transferring the signal chain design challenge of component selection, optimisation, and layout from the designer to the device.

The device combines a low-noise, fully differential analogue-to-digital converter (ADC) driver; a stable reference buffer; and a high-speed 18-bit, 2 MSPS successive approximation register (SAR) ADC.

It also incorporates Analog Devices' iPassives technology, supplying crucial passive components with superior matching and drift characteristics, to minimise temperature dependent error sources.

A 7 mm × 7 mm BGA package, saves up to 75% more board space than multi-component equivalent solutions, enabling smaller-form-factor instruments without sacrificing performance.

The serial peripheral interface (SPI)-compatible, serial user interface is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using a separate digital interface voltage (VIO) supply.

With the integration of multiple common signal-processing and conditioning blocks into a single device, the ADAQ4003 reduces end system component count along with development cycle time for systems such as automatic test equipment, machine automation, process controls, medical instrumentation, and digital control loops.
