DAC8811: Error in datasheet

Ted H

Part Number: DAC8811

Is there a typo in Equation (5) on page 16 of the DAC8811 datasheet?  The numerator of the first term to the right of the '=' sign is 2FB2 / RG1.  Should that read as 2RFB2 / RG1 or possibly just RFB2 / RG1?

    Great catch!

    You are correct, the equation has a typo: the "2" should be a "R".  For more information regarding a 4-Quadrant Multiplying DAC design please refer to the following URL:

    Below is what the equation should read as:
