Note 4:
The Temperature Coefficient of the adjusted 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 5:
The input bias currents are junction leakage currents which approximately double for every 10C increase in the junction temperature, T
. Due to limited
production test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the ambient
temperature as a result of internal power dissipation, Pd. T

Pd where

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 6:
Supply Voltage Rejection is measured for both supply magnitudes increasing or decreasing simultaneously, in accordance with common practice.
Note 7:
Settling time is defined here, for a unity gain inverter connection using 2 k
resistors for the LF155/6. It is the time required for the error voltage (the voltage
at the inverting input pin on the amplifier) to settle to within 0.01% of its final value from the time a 10V step input is applied to the inverter. For the LF357, A
V
= 5,
the feedback resistor from output to input is 2k
and the output step is 10V (See Settling Time Test Circuit).
Note 8:
Max. Power Dissipation is defined by the package characteristics. Operating the part near the Max. Power Dissipation may cause the part to operate outside
guaranteed limits.
