NOTES:
13. Tested with low dielectric absorption integrating capacitor.
14. 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 oper-
ation the junction temperature rises above the ambient temperature as a result of internal power dissipation, P
D
. T
J
= T
A
+ R
θ
JA
P
D
where R
θ
JA
is the thermal resistance from junction to ambient. A heat sink can be used to reduce temperature rise.
15. The temperature range can be extended to 70
o
C and beyond if the Auto-Zero and Reference capacitors are increased to absorb the
high temperature leakage of the 8068. See note 14 above.
16. System Electrical Specifications are not tested; for reference only.
