description

The uA747 is a dual general-purpose operational

amplifier featuring offset-voltage null capability.

Each half is electrically similar to uA741.

The high common-mode input voltage range and

the absence of latch-up make this 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 uA747C is characterized for operation from
