Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heatsink may be required to keep the junction temperature
below the absolute maximum when the output is shorted indefinitely.
Note 3: The LTC6903CMS8, LTC6904CMS8, LTC6903IMS8, and
LTC6904IMS8 are guaranteed functional over the operating temperature
range of –40 C to 85 C. The LTC6903HMS8 and LTC6904HMS8 are
guaranteed functional over the extended operating temperature range of
–40 C to 125 C.
Note 4: The LTC6903CMS8 and LTC6904CMS8 are guaranteed to meet
the specified performance limits over the 0 C to 70 C temperature range

and are designed, characterized and expected to meet the specified
performance from –40 C to 85 C but are not tested or QA sampled at
these temperatures. The LTC6903IMS8 and LTC6904IMS8 are guaranteed
to meet the specified performance limits over the –40 C to 85 C
temperature range. The LTC6903HMS8 and LTC6904HMS8 are
guaranteed to meet the specified performance limits over the –40 C to
125 C temperature range.
Note 5: All values are referenced to V
Note 6: Guaranteed by design and not subject to test.
Note 7: Parts with tighter frequency accuracy are available. Consult LTC
