8. The input bias currents are junction leakage currents which approximately double for every 10
9. This is the only component that causes error in dual-slope converter.
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
resistance from junction to ambient. A heat sink can be used to reduce temperature rise.
