Operational
Amplifiers (Op Amps)
Operational amplifiers are fundamental electrical elements that are often
used in instrumentation and control. And, by the way, they are usually
called "op-amps",
-
Why learn about op-amps?
-
They are widely used in
instrumentation and control.
-
They can be used to build
filters to filter noise out of signals.
-
They can be used to manipulate
signals, like adding two signals together (like from a microphone and a
guitar mike) or to integrate and differentiate signals, or to "isolate"
signals from sources that degrade when loads are attached.
-
What background should
you have to study op-amps?
-
What do you need to know
about operational amplifiers?
-
You need to know how to
power them with power supplies.
-
You need to know how to
build basic operational amplifier circuits like fixed-gain amplifiers,
summers, integrators and isolation amplifiers.
-
You need to know about
limitations of operational amplifiers.
-
What do you need to get
out of this unit?
-
When you are finished
with this unit you should be able to do the following.
-
Connect operational amplifiers
to power supplies in a circuit.
-
Be able to specify component
values and use operational amplifiers for inversion (change sign), summation,
and isolation.
-
What are you going to
learn about?
-
What if you need more
information?
-
Check these manufacturer's
specification sheets.
