NOTES: 1. Unless otherwise noted: TC = 25°C, DC input specifications are ± value given, power supply voltage is typical rating.

2. Long term operation at the maximum junction temperature will result in reduced product life. Derate power dissipation to achieve

high MTTF.

3. +V

4. Rating applies if output current alternates between both output transistors at a rate faster than 60Hz.

5. Supply current increases with signal frequency. See graph on page 4. Applies to each amplifier.

6. Rating applies when the heatslug of the DK package is soldered to a minimum of 1 square inch foil area of a printed circuit board.

7. Rating applies with the JEDEC conditions outlined in the Heatsinksing section of this datasheet.

8. Rating applies when power dissipation is equal in two amplifiers.
