Applications and Experiments for the Operational Amplifier Trainer
Students wire op-amp circuits with 2 mm patch cords, feed them from the on-board supplies and function generator, and compare measured gain or waveforms with theory. The trainer suits linear IC and analog electronics practicals in B.Tech, diploma and B.Sc. electronics courses, and op-amp modules in ITI and vocational electronics training.
- Inverting, non-inverting, buffer and comparator circuits, with output waveforms displayed on an Oscilloscope.
- Adder, subtractor, integrator and differentiator experiments, checking DC levels on a Digital Multimeter.
- High-pass and low-pass filters, square-wave generators and logarithmic amplifiers.
- Voltage-controlled current source and current-controlled voltage source circuits.
Check IC orientation, supply polarity and connections before switching on, and never insert or remove ICs while power is applied.
Standard Scope of Supply
Each trainer is delivered with a set of 2 mm patch cords and a user manual. A digital multimeter and an oscilloscope are optional accessories rather than standard contents, and either can be added to the same quotation if your laboratory needs them for measurements.
Packing, MOQ and Lead Time
You can ask for a quotation for a single op-amp trainer or for one per bench in an analog electronics laboratory. Science Lab Supplies, a physics instruments supplier in India, sets out packing, delivery time and price for that quantity, and meters or other electronics trainers can be listed alongside.
Science Lab Supplies, which holds an Importer-Exporter Code, can ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Request a price on the contact page, collect apparatus in the enquiry cart, or read the lab tender page before a tender submission.
Frequently Asked Questions
Which op-amp IC does the trainer use?
It has two IC 741 operational amplifiers with every pin brought out to 2 mm banana sockets, plus 14-pin and 16-pin ZIF sockets for fitting other ICs during experiments.
What power supplies are built in?
The trainer provides IC-regulated fixed ±5 V and ±12 V DC at 250 mA and a variable 1.2–10 V DC supply at 250 mA, running from a 230 V AC, 50 Hz mains input.
Are a multimeter and oscilloscope included?
No. A digital multimeter and an oscilloscope are optional accessories, not part of the standard kit. Either can be quoted with the trainer if your laboratory does not already have one.
Is the trainer made by Science Lab Supplies?
Yes. As a science apparatus manufacturer in India, Science Lab Supplies builds the op-amp trainer in its Saha, Ambala factory, and laboratories and distributors receive quotations from the factory directly.
