The ● denotes specifications which apply over the full operating
temperature range.
Note 1: Differential input voltages greater than 1V will cause excessive
current to flow through the input protection diodes unless limiting
resistance is used.
Note 2: This parameter is guaranteed by design and is not tested.
Note 3: Power supply rejection ratio is measured at the minimum supply
voltage.
Note 4: This parameter is not 100% tested.
Note 5: The LT1097 is designed, characterized and expected to meet these
extended temperature limits, but is not tested at –40°C and 85°C.
Guaranteed I grade parts are available; consult factory.
