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 6: Guaranteed by design and not subject to test.

Note 7: Parts with tighter frequency accuracy are available. Consult LTC

Marketing for details.
