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.

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.
