Study of Operational Amplifier as Sine to Square Wave Converter Manufacturer,Supplier and Exporter in India
Product Code : EL-COA-1141
Jlab Export is a leading Study of Operational Amplifier as Sine to Square Wave Converter Manufacturer,and suppliers in India
Study of Operational Amplifier as Sine to Square Wave Converter (code EL-COA-1141) is an electronics trainer that turns a sine wave into a square wave with a zero-crossing detector, using a comparator on a single supply. A voltage divider biases the reference input, and a sine input with peaks of −5 V and +5 V is first shifted to a 0 V to 5 V sinusoid before it reaches the comparator. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Sine to Square Wave Converter Used For?
It is used in B.Sc. electronics, engineering, polytechnic and ITI/TVET labs. A zero-crossing detector compares the input with a reference: each time the sine wave crosses that level the output switches state, so the output is a square wave at the same frequency as the input.
The single-supply arrangement is the instructive part. A comparator powered from one supply cannot handle an input that swings below ground, so the −5 V to +5 V sine is shifted up to sit between 0 V and 5 V, and the voltage divider sets the reference at the middle of that range — the point that corresponds to the original zero crossing. Students view input and output on an oscilloscope and compare the timing of each edge with the crossings. Noise near the crossing can cause extra transitions; adding hysteresis, as in a Schmitt trigger, removes them.
What to Specify When Ordering
- Quantity — the minimum order is 10 trainers.
- Panel details — state any supply, op amp or component values you require, plus a function generator or oscilloscope if needed.
Frequently Asked Questions
How does the trainer convert a sine wave into a square wave?
With a zero-crossing detector: the comparator output changes state every time the sine wave crosses the reference level, producing a square wave of the same frequency.
Why is the input shifted to 0 V to 5 V?
Because the circuit uses a single-supply comparator, which cannot accept negative inputs; the shift keeps the whole signal within the supply.
How is it different from the Schmitt trigger trainer?
This trainer uses a single reference level. The Schmitt trigger adds positive feedback for two thresholds, which makes switching immune to small amounts of noise.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its Ambala works in Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of electronics trainers and lab instruments in India, incorporated in 2017 and working from Hargolal Road, Ambala, Haryana. The sine to square wave converter is built at JLab’s own works rather than sourced from a trader, so colleges, dealers and importers buy direct from the maker and every unit is inspected before dispatch. JLab exports worldwide and ships to buyers in every region — for example Tajikistan in Central Asia, Mozambique in East Africa, Thailand in Southeast Asia, Honduras in Central America and the Caribbean and Germany in Western Europe.
