Analog Devices Inc. ADAQ4370-4 μModule® Data Acquisition Solution

Analog Devices Inc. ADAQ4370-4 μModule® Data Acquisition (DAQ) Solution is a quad-channel, 16-bit precision DAQ signal chain solution. This device reduces the development cycle of a precision measurement system by transferring the signal-chain design challenges of component selection from the designer to the device. The ADAQ4370-4 solution features an on-chip oversampling function, 0.01% typical gain error, 0.8ppm/°C typical gain drift, and a high-speed serial interface. Typical applications include lab-grade battery test systems, sonar, power quality monitoring, data acquisition systems, and motor control position feedback.
