Product Details

The ADAQ4001 is a μModule® precision data acquisition (DAQ), signal chain solution that reduces the development cycle of a precision measurement system by transferring the signal chain design challenge of component selection, optimization, and layout from the designer to the device.

Using system-in-package (SIP) technology, the ADAQ4001 reduces end system component count by combining multiple common signal processing and conditioning blocks into a single device. These blocks include a high resolution 16-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.

Using Analog Devices, Inc., iPassives® technology, the ADAQ4001 also incorporates crucial passive components with superior matching and drift characteristics to minimize temperature dependent error sources and to offer optimized performance (see Figure 1 in the data sheet). Housing this signal chain solution in a small, 7 mm × 7 mm, 0.80 mm pitch, 49-ball CSP_BGA enables compact form factor designs without sacrificing performance and simplifies end system bill of materials management. This level of system integration makes the ADAQ4001 much less sensitive to printed circuit board (PCB) layout while still providing flexibility to adapt to a wide range of signal levels.

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 VIO supply. Specified operation of the ADAQ4001 is from −40°C to +125°C.
