ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

If an input goes beyond the supply range, the input current should be

limited to 10mA.

Note 3: A heat sink may be required to keep the junction temperature

below absolute maximum.

Note 4: The LT1995C and LT1995I are guaranteed functional over the

operating temperature range of –40

°C to 85°C.

Note 5: The LT1995C is guaranteed to meet specified performance from

0

°C to 70°C. The LT1995C is designed, characterized and expected to

meet specified performance from –40

°C to 85°C but is not tested or QA

sampled at these temperatures. The LT1995I is guaranteed to meet

specified performance from –40

°C to 85°C.

Note 6: Thermal resistance (

connected to the leads. The specified values are for short traces connected

to the leads. If desired, the thermal resistance can be reduced slightly in

the MS package to about 130

°C/W by connecting the used leads to a

larger metal area. A substantial reduction in thermal resistance down to

about 50

°C/W can be achieved by connecting the Exposed Pad on the

bottom of the DD package to a large PC board metal area which is either

Note 7: Input offset voltage is pulse tested and is exclusive of warm-up

configuration. The equivalent input offset of the internal op amp can be

Note 8: Full Power bandwidth is calculated from the slew rate measure-

ment: FPBW = SR/2

Note 9: This parameter is not 100% tested.

Note 10: The input offset of the internal op amp is calculated from the
