Description
The 741 Op-amp chip is designed to accept two inputs on pins 2 and 3. The difference between the inputs is amplified to give the output.
Features and Applications
If the voltage on pin 2 is greater than pin 3 the output is negative. If pin 3 is greater than pin 2 the output is positive.
The Op-amp gives a voltage gain as opposed to a transistor which gives a current gain.
Uses: Switching, amplifiers, oscillators and analogue computing.
Data:
Pin
- OFFSET NULL not normally used
- inverting input
- non inverting input
- 0V is connected to the zero supply
- OFFSET NULL not normally used
- OUTPUT
- positive (+ve) supply voltage (+3V to +18V)
OFFSET NULL is used to balance output in high gain applications.
