All specifications are measured at the worst case 4.5 V supply voltage. 2 The maximum specifications at −40°C < TA < +85°C and −40°C < TA < 0°C are guaranteed from characterization. 3 RH is relative humidity (see the Humidity Effects section for more information). 4 The typical specifications are equal to the average plus the standard deviation of the distribution from characterization. 5 The guard offset voltage is the voltage difference between the guard output and the noninverting input.
