OPERATING CONDITIONS
CALCULATING THE DUT’S INPUT OFFSET VOLTAGE
CONVERTING INPUT OFFSET VOLTAGE TO OTHER PARAMETERS
This board works most effectively at room temperature (near +25°C). Measurements
at other temperatures should be done in an oven where the air velocity is minimal.

shown in Equation 2-1.
EQUATION 2-1:
2.6.1
Changing the bias voltages changes the input offset voltage. Microchip’s application
note AN1177 discusses in detail how these changes in V
found in our data sheets. The following list summarizes the parameters that contribute
to V
