(One Channel)

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

Operating ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. For ensured

specifications and test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are specified by design, test,

or statistical analysis. The ensured specifications apply only for the test conditions listed. Some performance characteristics may change

when the device is not operated under the listed test conditions.

(2)

Running the 1 MHz to 30 MHz test pattern at 1080i this part will dissipate approximately 9.2 W. This is the commonly accepted test

pattern that is representative of the worst case high frequency content for normal television viewing. This is the pattern used to estimate

the worst case power dissipation of the LM2450 in its normal application. It is recommended to use a heat sink with a thermal resistance

of 5.4°C/W or better.
