UA741 通用运算放大器

The uA741 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 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 uA741C is characterized for operation from 0°C to 70°C. The uA741I is characterized for operation from -40°C to 85°C.The uA741M is characterized for operation over the full military temperature range of -55°C to 125°C
