An audio mixer—commonly referred to as a mixing console or mixing board—is a critical component in professional audio signal processing. It facilitates the combining, routing, and adjustment of multiple audio inputs from sources such as microphones, instruments, and playback systems. Available in analog, digital, or hybrid formats, modern mixers offer precise control over parameters like gain, equalization, panning, and effects routing, ensuring optimal tonal balance and clarity across all … [Read more...]

DC-DC switching regulators are used to change the voltage efficiently from one DC to another. So, high-efficiency DC to DC regulators come in three basic topologies step-up or boost, step-down or buck & step-up/step-down or buck/boost. The boost converter is utilized to generate a higher DC output voltage, the buck converter is used to produce a low DC output voltage & finally, the buck or boost converter is utilized to produce an output voltage greater than, less than, or equivalent to … [Read more...]

Generally, pressure, humidity, and ambient temperature must be detected frequently within embedded products. So if there is any sensor that has these three sensors, it will be very convenient. So BME280 IC from Bosch's fulfills all these requirements. This is a combined pressure, temperature, and digital humidity sensor, located within a remarkably small metal-lid LGA box. So its compact size & low power utilization provide a benefit over other types of battery-powered gadgets like GPS … [Read more...]

A current sensor is a significant component within various electronic and electrical systems which helps to ensure that devices and equipment operate efficiently and safely. So this current sensor measures the sum of electric current supplied throughout a conductor and generates a signal that is proportional to that current. Here, the output signal can be an analog voltage, digital output, or current. Thus, the generated signal can be used to show the measured current within an ammeter (or) … [Read more...]

PWM controller ICs are simple and fixed-frequency control chips that can control nearly any power topology, like boost, flyback, push-pull, buck, forward, etc. Thus, the PWM controller ICs also incorporate a complete set of protections for improved robustness and consistency, even in an extensive temperature range for outdoor applications. Thus the result will be a reduction in the number of outside components, reducing converter cost and size. This article explores its TL494 IC design like pin … [Read more...]

Monolithic three-terminal linear voltage regulators appeared nearly two decades ago, which are simple to use & not expensive. So these regulators quickly eclipsed discrete and previous monolithic building blocks to dominate the market. LT1070 IC is a high power switching regulator manufactured previously by Linear Technology but acquired by Analog Devices Inc. While designing any circuit with this IC, some important things need to be considered like layout, power supply decoupling, … [Read more...]
