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
0
°
C to 70
°
C; the uA747M is characterized for
operation over the full military temperature range
of – 55
°
C to 125
°
C.
