Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: A heat sink may be required to keep the junction temperature
below the absolute maximum. This depends on the power supply voltage
and how many amplifi ers are shorted.
Note 3: The LTC6078C/LTC6079C and LTC6078I/LTC6079I are guaranteed
functional over the operating temperature range of –40°C to 85°C. The
LTC6078H/LTC6079H are guaranteed functional over the operating
temperature range of –40°C to 125°C.
Note 4: The LTC6078C/LTC6079C are guaranteed to meet specifi ed
