The
q
denotes specifications that apply over the full operating
temperature range.
Note 1:
A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 2:
The LT1492/LT1493 are designed, characterized and expected to
meet these extended temperature limits, but are not tested at – 40°C and
85°C. Guaranteed I grade parts are available. Consult factory.
Note 3:
This parameter is not 100% tested.
Note 4:
Guaranteed by correlation to V
S
= 3.3V and V

±10V
on
±15V
supplies.
Note 6:
Most LT1492/LT1493 electrical characteristics change very little
with supply voltage. See the 5V tables for characteristics not listed in the
3.3V table.
