__TOC__


=====Description=====

The [http://en.wikipedia.org/wiki/Operational_amplifier '''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.
