Unique gallstone hybrid amplifier

Class D audio amplifiers have many advantages over traditional Class A, Class B, or Class AB linear amplifiers. Linear amplifiers can have higher efficiency at very low signal levels, depending on how they are biased, but as the output signal level increases, this advantage disappears and Class D amplifiers perform

　　introduction 　　Accurate measurement of voltage requires minimizing the effects of the instrument wiring to the circuit being tested. Typical digital voltmeters (DVMs) use 10M resistor networks to keep loading effects to inconspicuous levels, even though this can cause significant errors, especially in higher voltage

Data from the World Health Organization (WHO) show that the number of deaths from traffic accidents is increasing every year worldwide, while the number of deaths from traffic accidents in Europe is decreasing. (1) Based on this information, the study found a causal relationship between the speed at which people rec

Compared with the previous structure, the installation area is reduced by about 46%! ROHM develops current detection amplifier IC "BD14210G-LA " with ±1% accuracy The input voltage range is -0.2V to +26V, which is very suitable for current detection in 12V and 24V power supply applications.

O Introduction 　　 The low noise amplifier (LNA) is an important component of the front end of the RF receiver. Its main function is to amplify the weak signal received, with a high enough gain to overcome the noise of subsequent stages (such as mixers) and to reduce the interference of additional noise as little as

Figure 3 is a dual-channel conversion amplifier with differential input. According to the feedback resistor value in the figure, a voltage gain of 2 can be obtained. An adjustable compensation capacitor is connected to pin 5, and the best bandwidth, settling time and passband gain flatness can be obtained by adjust

As the most common linear voltage regulator, 7805 is familiar to everyone. In addition to the LDO function, the 78 series chips can also be used for other circuit functions, such as simple constant current circuits, adjustable voltage regulator circuits, amplifier circuits, etc. I saw a circuit on th
