Each half is electrically similar to uA741. The high common-mode input voltage range and the absence of latch-up make this amplifier ideal for voltage-follower applications. The device is short-circuit protected and the internal frequency compensation ensures stability without external components. A low-value potentiometer may be connected between the offset null inputs to null out the offset voltage as shown in Figure 2. The uA747C is characterized for operation from 0°C to 70°C; the uA747M is characterized for operation over the full military temperature range of −55°C to 125°C. uA747m . . .

All voltage values, unless otherwise noted, are with respect to the midpoint between VCC + and VCC −. 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.
