Note 3. The temperature coeficient of the adjust input offset voltage changes only a small amount

(0.5µV/°C typically) for each mV of adjustment from its original unadjusted value. Common–

mode rejection and open loop voltage gain are also unaffected by offset adjustment.

Note 4. The input bias currents are junction leakage currents which approximately double for every

10°C increase in the junction temperature, TJ. Due to limited production test time, the input

bias currents measured are correlated to junction temperature. In normal operation the junc-

tion temperature rises above the ambient temperature as a result of internal power dissipa-

tion, Pd. TJ = TA + RthJC Pd where RthJC is the thermal resistance from junction to ambient.

Use of a heat sink is recommended if input bias current is to be kept to a minimum.

Note 5. Supply Voltage Rejection is measured for both supply magnitudes increasing or decreasing

simultaneously, in accordance with common practice.
