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.

production test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the ambient

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

Ω resistors for the LF155/6. It is the time required for the error voltage (the voltage

the feedback resistor from output to input is 2k

Ω 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
