How Does It Compare with Other JLab Op Amp Trainers?
| Trainer | Circuits listed | Power supplies listed | Other listed details |
|---|---|---|---|
| This trainer (EL-COA-1135) | Unity-gain buffer, non-inverting, inverting, summing and difference amplifier | Three DC regulated: 0 to ±15 V and 0 to 6 V | — |
| Operational Amplifier as Inverting and Non Inverting Amplifier | Inverting and non-inverting amplifier | ±15 V DC; 500 mA | Resistances connected externally; printed circuit diagram |
| Operational Amplifier Trainer | Inverting, non-inverting, summing and difference amplifier | 0–5 V DC variable (two), +12 V DC fixed | Circuit printed on an aluminium front panel; power cord, patch cords and instruction manual |

This is the only trainer in the group whose listing includes the unity-gain buffer stage alongside the summing and difference amplifiers. Pick the two-circuit model when only the inverting and non-inverting experiments are on the syllabus, and the breadboard kit when students should assemble each circuit themselves.
What Is the Study of Operational Amplifier Trainer Used For?
It covers the introductory op amp applications taught in undergraduate electronics and physics practicals, polytechnic diploma labs and ITI/TVET electronics courses. The unity-gain buffer (voltage follower) feeds the output straight back to the inverting input, so the output follows the input with a gain of one while the very high input impedance stops the circuit loading the source. The inverting and non-inverting amplifiers show how the feedback and input resistors set the gain. The summing amplifier is an inverting amplifier with several input resistors, and its output is the negative of the weighted sum of the inputs. The difference amplifier amplifies only the difference between two inputs, so a voltage common to both is rejected when the resistor ratios match.
In a typical session students set DC input voltages, measure the output with a multimeter, and check each result against the expected gain or sum. Keep inputs small enough that the output stays below the supply limits, and switch off before rewiring a circuit.
What to Specify When Ordering
- Quantity — the minimum order is 10 trainers; plan one per student group for a full practical class.
- Measuring instruments — no meter is named in this listing, so add a digital multimeter to the enquiry if your lab needs one.
- Panel and accessories — ask for details of the panel layout, connecting leads and manual if your tender specifies them.
Frequently Asked Questions
Which op amp circuits can be studied on this trainer?
Five: the unity-gain buffer stage, non-inverting amplifier, inverting amplifier, summing amplifier and difference amplifier. Together they cover the basic linear applications in most first op amp practicals.
What power supplies are built in?
Three DC regulated power supplies, listed as 0 to ±15 V and 0 to 6 V. The listing does not break down which output each range belongs to, so ask JLab for the full supply details if your specification needs them.
Is a meter included?
No meter is named in this listing. A digital multimeter can be quoted as a separate item on the same enquiry.
How is it different from the Operational Amplifier Trainer?
Both cover inverting, non-inverting, summing and difference amplifiers. This model also lists the unity-gain buffer and three regulated supplies including 0 to ±15 V, while the Operational Amplifier Trainer lists two variable 0–5 V supplies, a fixed +12 V supply and patch cords with a manual.
What is the minimum order and dispatch time?
The minimum order is 10 units, each sold individually. Dispatch is usually within 7–10 working days, after a visual check of every trainer; export transit depends on destination and freight mode.
What details does an export quotation need?
Quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, packing or labelling requirements and any tender reference.
Who makes the Study of Operational Amplifier trainer?
JLab (Jain Laboratory Instruments Pvt Ltd) manufactures it in Ambala, Haryana, India, and quotes as the maker.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of electronics and physics laboratory trainers, incorporated in 2017 with its works on Hargolal Road, Ambala, Haryana. The trainer is built in-house rather than bought from a trading house, so universities, colleges, dealers and importers order factory-direct, each unit gets a visual inspection before packing, and follow-up orders come back to the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Gabon in Central Africa, Norway in Northern Europe, Qatar in the Middle East, Algeria in North Africa and Turkmenistan in Central Asia. Tender buyers can find details on the lab tenders page.
