Analog Devices Inc. ADAQ4381-4 Quad-Channel DAQ Module

Analog Devices Inc. ADAQ4381-4 Quad-Channel Data Acquisition (DAQ) Module is designed for precision and efficiency. This device integrates a high resolution 14-bit, 4 MSPS ADC, ADC driver, and power management in a single device. Using SIP technology, the ADAQ4381-4 module reduces end-system component count by combining multiple common signal processing and conditioning blocks into a single device. The module supports fully differential and single-ended inputs, ensuring flexibility across various applications. Ideal for industrial automation, medical imaging, and test equipment, the ADAQ4381-4 combines high-speed performance with space-saving integration.
