Simple and exquisite 30W high-fidelity amplifier

28V output circuit composed of MAX4373 current amplifier The MAX4373 is a high-side current-sense amplifier with a comparator and reference. The latching output of the comparator (COUT1) allows the device to be used as a circuit breaker (see Figure 2 in the device data sheet). However, the circuit shown in the data

How to design a USB-powered 433.92MHz RF power amplifier to prevent overheating The International Telecommunication Union (ITU) has allocated the 433.92MHz Industrial, Scientific and Medical (ISM) band for use in Region 1, which geographically consists of Europe, Africa, Russia, Mongolia and the Arabian P

This paper discusses some weak signal amplification problems by combining the specific circuit introduction of SGI high-sensitivity two-line oscilloscope shaft power microvolt DC amplifier , in order to solve the problems of high gain, high common mode rejection ratio, high input impedance, low drift,

The tube amplifier has attracted many audiophiles with its sweet and soft sound quality. The tube amplifier introduced in this article is a single-ended Class A dual-channel model, which is very suitable for beginners to imitate. Circuit principle: Component select

Designers should be especially careful when using PWM amplifiers in noise-sensitive applications. Noise-sensitive applications include those using high-resolution encoders, ultrasonic transducers, or other low-level, medium-frequency signal generators. Grounding, shielding, and other circuit design techniques can allev

Audio power amplifiers are everywhere. Wherever there is music, there are audio amplifiers. Generations of electronic engineers have worked hard and spread their wisdom in this field. Audio amplifiers are to reproduce sound signals realistically and efficiently on speakers or headphones at a certain volume and power
