The high common-mode input voltage range and the absence of latch-up make the 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 µA741C is characterized for operation from 0°C to 70°C. The µA741I is characterized for operation from – 40°C to 85°C.The µA741M is characterized for operation over the full military temperature range of – 55°C to 125°C. µA741M . . .

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC – . 2. Differential voltages are at IN+ with respect to IN –. 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 µA741M only, the unlimited duration of the short circuit applies at (or below) 125°C case temperature or 75°C free-air temperature.
