1 These specifications represent the performance for 10 V ± 10% power supplies. All specifications are measured at the 10 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 These 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.

15 V NOMINAL ELECTRICAL CHARACTERISTICS

VSY = 16 V, VCM = VSY/2, TA = 25°C, unless otherwise noted. Typical specifications are equal to the average of the distribution from

characterization, unless otherwise noted. Minimum and maximum specifications are tested in production, unless otherwise noted.
