NOTES:
8. The input bias currents are junction leakage currents which approximately double for every 10^oC increase in the junction temperature, T_J. Due
to limited production test time, the input bias currents are measured with junctions at ambient temperature. In normal operation the junction
temperature rises above the ambient temperature as a result of internal power dissipation, P_D. T_J = T_A + R_θJAP_D, where R_θJA is the thermal
resistance from junction to ambient. A heat sink can be used to reduce temperature rise.
9. This is the only component that causes error in dual-slope converter.
