Applications and Experiments for the Operational Amplifier Trainer
Students follow the printed diagram, connect the front-panel resistors and capacitors to set up each configuration, select a supply and read the result on the moving-coil meters. Measured gains and outputs are then compared with calculated values, making the trainer a core item of analog electronics practicals.
- B.Sc. electronics and physics: inverting, non-inverting and unity-gain (buffer) amplifiers.
- Summing and difference amplifiers for op-amp mathematical operations.
- Diploma and B.Tech analog electronics: integrator and differentiator circuits.
- Sine-to-square and square-to-triangular waveform conversion, viewed on an Oscilloscope.
- Cross-checking voltages with a Digital Multimeter in ITI and vocational electronics training.
Check polarity before switching on, change connections only with the trainer off, and protect the moving-coil meters from knocks.
Standard Scope of Supply
One trainer main unit is supplied with its three built-in regulated DC supplies, two dual-range moving-coil meters and the front-panel resistors and capacitors. Patch cords, a manual and external instruments are not listed as standard and can be added to the quotation if required.
Packing, MOQ and Lead Time
Whether you need a single trainer or one for each bench of an analog electronics lab, ask for a quotation for that number. It confirms the packing, delivery time and price for the quantity, and oscilloscopes, multimeters or other trainers can appear on the same sheet.
Backed by its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Write in through the contact page, place items in the enquiry cart, or check the lab tender page for tender-based purchases.
Frequently Asked Questions
Which op-amp experiments can be done?
Ten applications are documented: inverting, non-inverting, summing, difference, integrator, differentiator, buffer, unity-gain amplifier, sine-to-square converter and square-to-triangular converter, all built from the front-panel components.
What supplies does the trainer provide?
It has three regulated DC supplies: two variable 0–1.5 V DC outputs rated at 150 mA, used as signal or input voltages, and one ±15 V DC dual supply for powering the op-amp circuits.
Are meters built in?
Yes. Two dual-range moving-coil meters are fitted, so input and output readings can be taken on the trainer itself. An oscilloscope is still useful for the waveform-conversion experiments and can be quoted separately.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer and assembles this trainer in its own Ambala factory at Saha, India. Quotations are prepared by the factory, so there is no trading margin or middleman between you and the maker.
