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: The inputs are protected by back-to-back diodes as well as ESD
protection diodes to each power supply. If the differential input voltage
exceeds 3.6V or the input extends more than 500mV beyond the power
supply, 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
indefi nitely.
Note 4: The LTC6255C/LTC6256C/LTC6257C and LTC6255I/LTC6256I/
LTC6257I are guaranteed functional over the temperature range of
–40°C to 85°C. The LTC6255H/LTC6256H/LTC6257H are guaranteed
functional over the temperature range of –40°C to 125°C.

Note 5: The LTC6255C/LTC6256C/LTC6257C are guaranteed to meet
the specifi ed performance from 0°C to 70°C. The LTC6255C/LTC6256C/
LTC6257C are designed, characterized and expected to meet specifi ed
performance from –40°C to 85°C but are not tested or QA sampled at
these temperatures. The LTC6255I/LTC6256I/LTC6257I are guaranteed
to meet specifi ed performance from –40°C to 85°C. The LTC6255H/
LTC6256H/LTC6257H are guaranteed to meet specifi ed performance
from –40°C to 125°C.
Note 6: Thermal resistance varies with the amount of PC board metal
connected to the package. The specifi ed values are for short traces
connected to the leads.
Note 7: The input bias current is the average of the currents through the
positive and negative input pins.
Note 8: Full power bandwidth is calculated from the slew rate FPBW =
