NOTES: 1. Unless otherwise noted: T_C = 25°C, DC input specifications are ± value given. Power supply voltage
is typical rating. C_c= 4.7pF.
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate
internal power dissipation to achieve high MTTF.
3. Although supply voltages can range up to ± 450V the input pins cannot swing over this range. The
input pins must be at least 30V from either supply rail but not more than 500V from either supply rail.
See text for a more complete description of the common mode voltage range.
4. Rating applies if the output current alternates between both output transistors at a rate faster than
60Hz.
5. Derate max supply rating .625 V/°C below 25°C case. No derating needed above 25°C case.
