ADAQ4380-4BBCZ

ADAQ4380-4BBCZ is a quad-channel precision data acquisition (DAQ) signal chain μModule solution that reduces the development cycle of a precision measurement system by transferring the signal chain design challenges of component selection, optimization, and layout from the designer to the device. Using system-in-package (SIP) technology, the ADAQ4380-4 reduces end system component count by combining multiple common signal processing and conditioning blocks into a single device. These blocks include a quad-channel, high resolution 16-bit, 4MSPS simultaneous sampling SAR ADC, low noise, fully differential ADC driver amplifier, a 3.3V precision voltage reference, low noise buffer amplifiers, and low-dropout linear regulator. Applications include lab grade battery test system, motor control current sense, motor control position feedback, sonar, power quality monitoring, data acquisition system, erbium-doped fibre amplifier (EDFA) applications, I and Q demodulation.
