 Ultralow noise, low offset voltage, and low drift amplifiers are used at the front end for amplification of the low-level signal from the load cell. The circuit yields 15.3 bit noise-free code resolution for a load cell with a full-scale output of 10 mV. Ultralow noise, low offset voltage, and low drift amplifiers are used at the front end for amplification of the low-level signal from the load cell.

 +<note important>Extremely important to note that the **EVAL-CN0216-ARDZ** is powered from the **VIN** connector on the Arduino Uno header.  This is because the bridge drive voltage of the EVAL-CN0216-ARDZ requires more than 5V to power the bridge.  Therefore it is required to supply power from the baseboard through the DC power connector in order for proper functionality.  The board will not work properly if you try only to power it from the USB.</note>
