Analog Devices Inc. ADAQ4003 18-Bit µModule® Data Acquisition System

Analog Devices Inc. ADAQ4003 18-Bit 2MSPS µModule® Data Acquisition System is a 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. The ADAQ4003 implements system-in-package (SIP) technology that reduces end system component count by combining multiple common signal processing and conditioning blocks into a single device. These blocks include a high-resolution 18-bit, 2MSPS successive approximation register (SAR), analog-to-digital converter (ADC), a low noise, fully differential ADC driver amplifier (FDA), and a stable reference buffer.

The ADI ADAQ4003 µModule Data Acquisition System incorporates iPassives® technology that consists of crucial passive components with superior matching and drift characteristics, to minimize temperature dependent error sources and offer optimized performance.

The signal chain solution is housed in a small, 7mm × 7mm, 0.80mm pitch, 49-ball CSP_BGA compact form factor that designs without sacrificing performance and simplifies the end system bill of materials management. This system integration level makes the ADAQ4003 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 1.8V, 2.5V, 3V, or 5V logic, using a separate VIO supply. The ADAQ4003 features a specified operation from -40°C to +125°C.
