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 VS = 3.3V and VS = ±15V tests.
Note 5: Slew rate is measured between
±5V on an output swing of ±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.
Note 7: Guaranteed by correlation to VS = 5V and VS = ±15V tests.
Note 8: Guaranteed by correlation to VS = 3.3V tests.
