CS4399-CNZR Overview
Presented in package 40-WFQFN Exposed Pad.In the Tape & Reel (TR) package, you can find this data acquisition unit.The recommended working temperature is -10°C~70°C in order to maintain normal operation.The outstanding DAC, Audio is what you paid.ADCs/DACs is best to mount this part through Surface Mount in order to save more space.For this unit, you should redo the circuit if your meter reads something other than 1.66V~1.94V for the supply voltage.In total, 40 terminations have occurred.The 1 function here gives access to high performance for whatever application you want to run.As a result of deploying 2 channels, this unit is able to efficiently perform complex tasks.This data acquisition unit should be powered by 1.8V voltage.An integrated data acquisition device with a 32-bit resolution is used in this application.
