741 Operational Amplifier

From DT Online

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

  1. OFFSET NULL not normally used
  2. inverting input
  3. non inverting input
  4. 0V is connected to the zero supply
  5. OFFSET NULL not normally used
  6. OUTPUT
  7. positive (+ve) supply voltage (+3V to +18V)

OFFSET NULL is used to balance output in high gain applications.
