Note: 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.

The inputs are protected by ESD protection diodes to

each power supply. If the input extends more than

500mV beyond the power supply, the input current

should be limited to less than 10mA.

A heat sink may be required to keep the junction

temperature below the absolute maximum rating when

the output is shorted indefinitely.

Thermal resistance varies with the amount of PC

board metal connected to the package. The specified

values are for short traces connected to the leads.

Full power bandwidth is calculated from the slew rate

FPBW =

SR/π • VP-P.
