What is a rail to rail amplifier?

Analog Devices High Speed ​​Optics (> 50 MHz) Analog Devices Rail-to-rail assemblies allow you to work with lower supply voltages, approach the tracks and provide a wider dynamic range. Equipped…

What is the voltage follower?

A voltage follower (also called unit gain amplifier, buffer amplifier and isolation amplifier) ​​is an op-amp circuit that has a voltage gain of 1. This means that the operational amplifier…

What is the lm386?

If you build a microcontroller sound sensor, you can install it on an LM386 based amplifier. It’s cheap, easily available and does not require too many external parts. A nice…

What is the function of lm339?

A dedicated voltage comparator will generally be faster than an operational amplifier for general use put into operation as a comparator. A dedicated voltage comparator can also contain additional functions…

What is an op amp and how does it work?

Well, the idea is to insert two electrical signals into the inputs, so the output changes accordingly. This takes the difference between the inputs and amplifications, then the operational amplifier…

What is a refractive index detector?

The refractive index (RI) is the only universal detector in HPLC. The detection principle involves measuring the variation of the refractive index of the effluent from the column passing through…

What is the function of laser diode?

A laser diode (LD), an injection laser diode (ILD) or a laser diode is a semiconductor device similar to a light emitting diode which is created at the junction of…

What is an IR photodiode?

An IR sensor is basically a device composed of a pair of IR LEDs and a photodiode collectively called optocouplers or optocouplers. The IR LED emits IR radiation, the reception…

What is the role of a LED in a circuit?

In electronics, an LED circuit or an LED driver is an electrical circuit used to power a light emitting diode (LED). The circuit must supply enough current to illuminate the…

What is the difference between SUHD and 4k?

UHD (and SUHD) ultra-high-definition TV – known as UHD, UltraHD, UHDTV and Super Hi-Vision – is really another term for 4K in most cases. SUHD is the Samsung brand of…

What is the difference between HD and 4k?

The difference between Ultra HD and 4K. From a technical point of view, “Ultra High Definition” is actually a derivative of the 4K digital cinema standard. However, while your local…

What is the work of a diode?

A vacuum tube diode has two electrodes, a plate (anode) and a heated cathode. The most common function of a diode is to allow an electric current to pass in…

What is a diode and what is it used for?

The diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators and oscillators. The fundamental property of a diode is its tendency to…
