3. Conditions for Input Offset Voltage Sensitivity:
a. Bias current derived from the regulator with an appropriate resistor connected from Terminal 1 to the bias terminal on the amplifier
under test V+ is reduced to +13V for V+ sensitivity and V- is reduced to -13V for V- sensitivity.
b. V+ Sensitivity in µV ⁄ V = V-----O-----f--f--s---e----t---–-----V----O-----f--f--s----e----t---f--o---r--1--+--V--1---3---V------a---n----d--------1---5---V------S----u---p----p---l-i--e---s-- ,
