ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those beyond which the life of the
device may be impaired.
Note 2:
A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 3:
The inputs are protected by ESD diodes to the ground. If the input
voltage exceeds –0.3V below ground, the input current should be limited
to less than 10mA.
Note 4:
The LT6700CS6-1/-2/-3 and LT6700IS6-1/-2/-3 are guaranteed
functional over the operating temperature range of – 40°C to 85°C. The
LT6700HS6-1/-2/-3 are guaranteed functional over the operating
temperature range of –40°C to 125°C.
Note 5:
The LT6700CS6-1/-2/-3 are guaranteed to meet the specified
performance from 0°C to 70°C. The LT6700CS6-1/-2/-3 are designed,
characterized and expected to meet specified performance from – 40°C to
85°C but are not tested or QA sampled at these temperatures. The
LT6700IS6-1/-2/-3 are guaranteed to meet specified performance from
–40°C to 85°C. The LT6700HS6-1/-2/-3 are guaranteed to meet specified
performance from –40°C to 125°C.
