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: Input pins (+IN, –IN, V
diodes to either supply. If the inputs should exceed either supply voltage,
the input current should be limited to less than 10mA. In addition, the
inputs +IN, –IN are protected by a pair of back-to-back diodes. If the
differential input voltage exceeds 1.4V, the input current should be limited
to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.

Note 4: The LTC6409C/LTC6409I are guaranteed functional over the
temperature range of –40°C to 85°C. The LTC6409H is guaranteed
functional over the temperature range of –40°C to 125°C.
Note 5: The LTC6409C is guaranteed to meet specified performance from
0°C to 70°C. The LTC6409C is designed, characterized and expected to
meet specified performance from –40°C to 85°C, but is not tested or
QA sampled at these temperatures. The LTC6409I is guaranteed to meet
specified performance from –40°C to 85°C. The LTC6409H is guaranteed
to meet specified performance from –40°C to 125°C.
Note 6: Input bias current is defined as the average of the input currents
flowing into the inputs (–IN and +IN). Input offset current is defined as the
difference between the input currents (I
