(TOP VIEW)
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
connectedbetweentheoffsetnullinputstonullout

2. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
4. The output may be shorted to ground or either power supply. For the uA747M only, the unlimited duration of the short circuit applies

All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified.
Full range for uA747C is 0°C to 70°C and for uA747M is –55°C to 125°C.
*On products compliant to MIL-STD-883, Class B, this parameter is not production tested.
NOTE 5: This typical value applies only at frequencies above a few hundred hertz because of the effects of drift and thermal feedback.
