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.
