NOTES:

1. Unless otherwise noted: T

given, power supply voltage is typical rating. Amplifier operated without boost feature.

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

internal power dissipation to achieve high MTBF.

3. Doubles for every 10°C of case temperature increase.

4. +V

stage supply voltages (boost voltages).

5. Rating applies if the output current alternates between both output transistors at a rate faster than

60Hz.

6. Power supply voltages +V
