If operating INA128 on +/-3.5V supplies, what is the calculation for the offset voltage of the output vs Power Supply with the Gain of 10?
Is this the correct approach based on electrical characteristic table specs?
offset voltage vs power supply (RTI) = 1 + 100/10 = 11uV/V
Given 3.5V supply, then supply change is 15V – 3.5V = 11.5V
So, 11.5V x 11uV/V = 126.5uV RTI
Since G=10, then offset at output would be 126.5uV x 10 = 1265uV = 1.265mv
