NOTES: 1. (All Min/Max characteristics and specifications are guaranteed over the Specified Operating Condi-
tions. Typical performance characteristics and specifications are derived from measurements taken
at typical supply voltages and TC = 25°C).
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate
power dissipation to achieve high MTTF.
3. +VS and –VS denote the positive and negative power supply rail respectively.
4. Rating applies if the output current alternates between both output transistors at a rate faster than
60Hz.
5. Derate max supply rating 0.625 V/°C below 25°C case. No derating needed above 25°C case.
