Note 5
Note 3. The temperature coeficient of the adjust input offset voltage changes only a small amount
(0.5
μ
V/
°
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, T
J
. 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, P
d
. T

where R
thJC
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.
