What Is the Operational Amplifier Applications Trainer Used For?
An operational amplifier amplifies DC as well as AC signals and can compute functions such as addition, subtraction, integration and differentiation, which is where the name comes from. This trainer takes students on to the circuits built around it: the op-amp as a function generator producing square and triangle waves, a half-wave precision rectifier, an active second-order high-pass filter, a voltage comparator and a zero crossing detector, a phase shift oscillator with its phase shift at every RC combination, and a Wien bridge oscillator with the gain factor it needs for a smooth sine wave.
What to Specify When Ordering
- Trainer — this applications trainer, or Experimentation of OP-AMP Characteristics for op-amp basics and characteristics.
- Quantity — the number of trainers.
- Single-circuit trainers — the oscillator and filter trainers below are separate items that can be added to the same enquiry.
Frequently Asked Questions
What does the Wien bridge oscillator experiment show?
The Wien bridge RC network passes one frequency with no phase shift but cuts its amplitude to a third, so the amplifier gain has to be close to 3 for the oscillation to keep going. With too little gain the oscillation dies away and with too much the sine wave clips, which is why the gain factor for a smooth sine wave is studied.
Why use a precision rectifier instead of a plain diode?
A plain diode does not conduct until the signal exceeds its forward voltage drop, so small signals are lost. Placing the diode inside the op-amp's feedback loop cancels that drop, so much smaller signals can be rectified.
What is a zero crossing detector?
It is a comparator whose reference is zero volts. Its output switches state every time the input passes through zero, so a sine wave in gives a square wave out, a building block of timing and frequency-measurement circuits.
How does the phase shift oscillator produce a sine wave?
An inverting op-amp shifts the signal by half a cycle, and the RC ladder adds further phase shift that brings the feedback back into step at one frequency. Measuring the shift at every RC combination shows how that frequency is set.
How does it differ from Experimentation of OP-AMP Characteristics?
Both have an on-board function generator giving sine, square and triangular waves and two variable DC supplies. This trainer covers op-amp applications such as oscillators, a precision rectifier, a high-pass filter and comparators, while Experimentation of OP-AMP Characteristics covers basic functions and characteristics such as summers, integrators, converters, CMRR and open-loop gain.
What should an export enquiry include?
Give the quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling instructions, and the tender reference if the order is for a tender.
Who manufactures this op-amp trainer?
Jain Laboratory Instruments Pvt Ltd (JLab) manufactures Operational Amplifier Applications in Ambala, Haryana, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer in India of analog and digital electronics trainers among other educational laboratory equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This trainer is built at JLab's own works rather than sourced from a trader, so colleges, schools, dealers and importers buy it factory-direct, each unit is visually inspected before dispatch, and repeat orders are dealt with by the manufacturer. JLab exports worldwide and can ship to buyers in every region, for example Bulgaria in Eastern Europe, the Dominican Republic in Central America and the Caribbean, Tonga in Oceania, Taiwan in East Asia and Sudan in North Africa. Tender buyers can refer to the JLab lab tenders page.
