... AD5441 TERMINOLOGY Relative Accuracy (INL) Relative accuracy or endpoint nonlinearity is a measure of the maximum deviation from a straight line passing through the endpoints of the DAC transfer function measured after adjusting for zero and full scale and is normally expressed in LSBs percentage of the full-scale reading. ...

... During any testing of the resistor ladder or R incoming inspection), V series switches. OUTPUT IMPEDANCE The output resistance of the AD5441 the case of the output capacitance, varies with the digital input code. This resistance, looking back into the I 10 kΩ (the feedback resistor alone when all digital inputs are low) and 7.5 kΩ ...
