Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
The LT1790S6 is guaranteed functional over the operating
temperature range of –40
°
C to 125
°
C.
Note 3:
If the part is stored outside of the specified temperature range, the
output voltage may shift due to hysteresis.
Note 4:
ESD (Electrostatic Discharge) sensitive device. Extensive use of
ESD protection devices are used internal to the LT1790, however, high
electrostatic discharge can damage or degrade the device. Use proper ESD
handling precautions.
