Simple and Low Cost IC Tester for Analog and Digital Labs
Abstract
Integrated Circuits (ICs) are the important component of each and every electronic circuit and can be used for wide variety of purposes. Sometime due to faulty ICs the circuit doesn’t work. It takes lot of efforts to troubleshoot the circuit and confirm whether the circuit is creating problem or the IC is faulty. So the proposed project is designed to confirm whether the IC under consideration is properly working or not. Unlike the IC testers available in the market today which are usually expensive, this IC tester is affordable and user-friendly. This Digital and Analog IC tester is constructed using microcontroller along with a keyboard and a display unit. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This IC tester can be used to test a wide variety of ICs which includes simple logic gates and also sequential and combinational ICs like flip-flops, counters, shift registers etc. This tester able to identify which particular logic gate is faulty in that ICs. This tester can also test frequently required analog ICs in Laboratories like Operational amplifiers, Timers etc.
