Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
The LTC6261I/LTC6262I/LTC6263I are guaranteed to meet may cause permanent damage to the device. Exposure to any Absolute specified performance from –40°C to 85°C. The LTC6261H/LTC6262H/ Maximum Rating condition for extended periods may affect device LTC6263H are guaranteed to meet specified performance from –40°C to reliability and lifetime. 125°C.
Note 2:
The inputs are protected by back-to-back diodes as well as ESD
Note 6:
Thermal resistance varies with the amount of PC board metal protection diodes to each power supply. If the differential input voltage connected to the package. The specified values are for short traces exceeds 3.6V or the input extends more than 500mV beyond the power connected to the leads. supply, the input current should be limited to less than 10mA.
