A voice modulator is an integrated circuit that changes the tone and pitch of a voice. An example of a voice modulator IC is HT8950 IC which can make seven steps down or up on the 8 Hz frequency of input voice. Thus, the modulator circuit using this IC uses different components, so it picks the input voice by using a microphone and pushbutton switch to step up the frequency, and the IC amplifies the output. Thus, this IC can be used in electronic systems like speech processors, telephones, toys, … [Read more...]

A boost converter is a DC-to-DC switching converter IC that efficiently increases the input voltage to a high output voltage. This voltage conversion is possible by storing energy in an inductor in the switch-on phase and releases to the load in the switch-off phase. So these are different kinds of DC-to-DC converters linear, switch mode, boost, buck, transformer-based buck-boost, and isolated. Power electronics applications need high output voltage as compared to the input source especially … [Read more...]

A voltage regulator that converts an input voltage to a regulated or a lower voltage by using a switching element is known as a high-frequency step-down switching regulator. So this voltage regulator can change the voltage from a power source to the voltage necessary by other systems within an electronic device. These regulators are more efficient than linear regulators in decreasing high input voltage to a lower or regulated voltage. A high switching frequency reduces the size of the components … [Read more...]

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 cha … [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...]
