UA741CN Datasheet – Single Operational Amplifier IC
General purpose operational amplifier
Package DIP 8 Pin
UA741CN overview
The UA741 is a high-performance monolithic operational amplifier constructed on a single silicon chip. It is intended for a wide range of analog applications. The high gain and wide range of operating voltages provide superior performances in integrators, summing amplifiers, and general feedback applications. The internal compensation network (6 dB/octave) ensures stability in closed-loop circuits.

Absolute Maximum Ratings
- Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
- Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating.
- Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins.
