description
The µA741 is a general-purpose operational amplifier featuring offset-voltage null capability. 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 internalfrequency 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.
