300W_Hi-Fi Amplifier Production

This article introduces a hybrid amplifier with great value. This machine meets the principle of "simple first" for "players" to build a machine, and is very suitable for the trial of "welders" of beginner audiophiles. Circuit principle: This machine is composed of a tube pre-stage SRPP (single-ended parallel push

When DTS software is launched in large quantities in the new wave of home theater, YAMAHA has launched a top-level AV amplifier with DTS/AC-3 (decoding) function, DSP-A1. The appearance design still inherits the style of YAMAHA's top models in the past. The huge body, iron-gray heavy metal panel, and noble wood guards

An audio amplifier is an electronic amplifier used to amplify a weak audio signal from an input such as a microphone into a high amplitude signal that is reproduced through a loudspeaker. This is a very simple hobby project suitable for beginners. This homemade mini amplifier circuit is suitable for honin

        introduction 　　In many bioelectric signal testing processes, it is necessary to amplify the output signal of the sensor with a bandwidth of tens of Hz, high internal resistance, and weak signal from the DC component to the bandwidth of tens of Hz. The reference design an amplification circuit for this sign

0 Introduction In the multimedia era, traditional Class A, Class B, and Class AB linear analog audio amplifiers can no longer meet the new development trends of green energy saving, high efficiency, and small size of electronic audio-visual LCD/PDP/OLED/LCOS/PDA due to their low efficiency and high energy c

Abstract: Using a preamp to increase the output magnitude of a J-type thermocoupler. The simple circuit provides compensation over temperature as well as calibration capability. The MAX430 is operated at a gain of 191 to convert the 52µV/°C output of the type J thermocouple to a 10mV/°C signal. The -2.2mV/°C tempco

If some basic layout guidelines are not followed, PCB design can limit the performance or reduce the reliability of a Class D amplifier. Some good PC board layout practices for Class D amplifiers are described below. The STA517B (175 watts per channel) digital power amplifier with two BTL outputs is used as an example,

This paper introduces a high-precision current/voltage conversion amplifier for electron beam exposure machine beam spot and beam current measurement. According to the specific situation that the beam current is extremely weak, in order to obtain the high-precision performance index requirements of ultra-low drift, ul
