(2) The input bias currents are junction leakage currents which approximately double for every 10°C increase in the junction temperature,
T
j
. Due to the 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, P

(3) Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with
common practice. V
