THE BREAD BOARD
The bread board consists of two terminal strips and two bus strips (often broken in the
centre). Each bus strip has two rows of contacts. Each of the two rows of contacts are a node.
That is, each contact along a row on a bus strip is connected together (inside the bread board).
Bus strips are used primarily for power supply connections, but are also used for any node
requiring a large number of connections. Each terminal strip has 60 rows and 5 columns of
contacts on each side of the centre gap. Each row of 5 contacts is a node. You will build your
circuits on the terminal strips by inserting the leads of circuit components into the contact
receptacles and making connections.
Incorrect connection of power to the ICs could result in them exploding or becoming
very hot with the possible serious injury occurring to the people working on the experiment!
Ensure that the power supply polarity and all components and connections are correct before
switching on power.

FUNCTIONING, PARAMETERS AND SPECIFICATIONS OF IC’S
IC 741 :
General Description:
The IC 741 is a high performance monolithic operational amplifier constructed using
the planer epitaxial process. High common mode voltage range and absence of latch-up
tendencies make the IC 741 ideal for use as voltage follower. The high gain and wide range
of operating voltage provide superior performance in integrator, summing amplifier and
general feed back applications.
