(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.

(2) The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 300 mV beyond

the power supply, the input current should be limited to less than 10 mA.

(3) 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 amplifiers are shorted. 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.
