Operating free-air temperature range 0 to 70 –55 to 125 °C
Storage temperature range –65 to 150 –65 to 150 °C
Case temperature for 60 seconds FK package 260 °C
Lead temperature 1,6 mm (1/16 inch) from case for 60 seconds J or W package 300 °C
Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds D or N package 260 °C
NOTES: 1. All voltage values, unless otherwise noted, are with respect to the midpoint between V
CC +
and V
CC –
.
2. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
4. The output may be shorted to ground or either power supply. For the uA747M only, the unlimited duration of the short circuit applies
at (or below) 125°C case temperature or 75°C free-air temperature.
