AD7891AS-1 Overview
Enclosed in the 44-QFP package.This data acquisition unit is available in the Tray package.To maintain normal operation, the working temperature is advised to be set as -40°C~85°C.You can get what you paid from this outstanding Data Acquisition System (DAS).To save more space, mount this part through Surface Mount.If your meter doesn't read 5V for the supply voltage as this unit is designed you better redo the circuit.There are 44 terminations in total.1 functions here to access high performance for whatever applications.By deploying 8 channels, this unit executes complicated tasks efficiently.5V is the common amount of voltage that should be applied to this data acquisition unit.Speaking of pin count, it has 44 pins.This is a high resolution 12-bit data acquisition device.In consideration of high-level analog source acquisition, 8 analog IN channels are implemented.
