NOTES:
7. The input bias currents are junction leakage currents which approximately double for every 10
o
C 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
.

, where R
θ
JA
is the thermal resistance from junction to ambient. A heat sink can be used to reduce temperature rise.
8. This is the only component that causes error in dual-slope converter.
