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.

µA741Y chip information  
This chip, when properly assembled, displays characteristics similar to the µA741C. Thermal compression or  
ultrasonic bonding may be used on the doped-aluminum bonding pads. Chips may be mounted with conductive  
epoxy or a gold-silicon preform.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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.

All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified. Full range for  
the µA741C is 0°C to 70°C, the µA741I is 40°C to 85°C, and the µA741M is 55°C to 125°C.  
NOTE 5: This typical value applies only at frequencies above a few hundred hertz because of the effects of drift and thermal feedback.
