Analog Electronics deals with electronic systems that has a continuous variable signal. In this section we will discuss about various analog electronic projects that can be used to design your own amplifiers, oscillators, filters, analog converters, waveform generators and other analog circuits as required by your application.
TSV792 from STMicroelectronics is a high bandwidth (50MHz) low offset (200µV) rail-to-rail 5V Op amp that enables accurate amplification of high-frequency signals in various industrial and smart home systems. This new device offers a fast slew rate of 30V/µs and is suitable to be used in photodiode-signal conditioning in battery-powered smoke detectors.

DIY Music players are fun to build, and we previously built a few music players using Arduino and a dedicated MP3 module. Now we are using the ESP32 speaker output to build an interesting audio player, in which you can add sound effects by just connecting an extra speaker to the ESP32. Here we will use LM386 and a speaker with ESP32 to play music files. The audio…
In this article, we are building an AC Fan Regulator Circuit, which is able to control the speed of the fan by restricting the flow of current to the fan. The term AC Ceiling Fan Regulator is a mouthful, hence we will simply call it a fan regulator from now on. A fan regulator circuit is a crucial component that is used to increase or decrease the speed of an AC Fan/motor…
An Analog to Digital Converter (ADC) is a type of device that helps process real-world analog signals for digital systems. To understand real-world data like temperature, humidity, pressure, and position, we need transducers that convert these measurements into electrical signals. Since the majority of devices we use at the moment are digital, this conversion becomes…
Home automation systems are increasingly gaining popularity day by day, and nowadays it's become easy to turn on & off certain appliances by using some simple control mechanism like a relay or a switch, we have previously built many Arduino based Home Automation Projects using relays. But there are many home appliances that require control of this AC power rather than…
Designers requiring longer uptime for industrial automation applications can accelerate troubleshooting and communicate across larger networks with the MAX33012E controller area network (CAN) bus transceiver and the MAX33072E RS-485 half-duplex transceiver from Maxim Integrated Products. These devices are designed to increase industrial system uptime for factory-floor…
Saelig Company, Inc. has introduced the Euroquartz EQXO-75UIE, an Extended Industrial Temperature ruggedized high-reliability SMD clock oscillators, that provides reliable operation with excellent frequency stability for an operating temperature range of -40° to +105°C. All the EQXO-75UIE crystals are pre-aged with an aging specification of ±1ppm maximum for the first…
ROHM has introduced the BD77501G, a high-speed ground sense CMOS op-amp designed especially for industrial and consumer equipment that require high speed sensing such as anomaly detection systems used in measurement and control equipment along with sensors that work with very small signals. The EMARMOUR series of op-amps and comparators have been developed to provide…
A potentiometer is a mechanical device using which one can set the resistance according to the desired value, thus changing the current passing through it. There exist many applications for a potentiometer, but mostly, a potentiometer is used as a volume controller for audio amplifiers. The digital volume control circuit is an electronic circuit that accurately adjusts…
The pH scale is used to measure the acidity and basicity of a liquid. It can have readings ranging from 0-14, where 0 shows the most acidic liquid and 14 shows the most basic liquid. 7 pH is for neutral substances that are neither acidic nor basic. Now, pH plays a very important role in our lives, and it is used in various applications. For example, it can be used in a…
Sometimes, we might need an AC bulb flasher circuit that can blink a series of bulbs in a particular time interval for decorative purposes. By controlling the flashing time interval and sequence, we can make a series of bulbs look beautiful for outdoor decoration in Cafeteria, Restaurants, etc. or even used it for heavy Christmas light decoration, so here I have shared a…
An op-amp plays a very crucial role when it comes to designing circuits with analogue components. But while implementing such op-amp based circuits, there are situations where one or more op-amps are left unused, this causes undesirable behaviour in one or all of those unused op-amps thus impacting total system performance.
To avoid this type of…
