Short-Circuit Protection Offset-Voltage Null Capability Large Common-Mode and Differential Voltage Ranges No Frequency Compensation Required No Latch-Up Designed to Be Interchangeable With Fairchild µA741
The high common-mode input voltage range and the absence of latch-up make the amplifier ideal for voltage-follower applications. The device is shortcircuit 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 device is characterized for operation from 0°C to 70°C. The µA741M device (obsolete) is characterized for operation over the full military temperature range of –55°C to 125°C.
