Label: style blog HTTP color ar OS SP file on The boss gave two audios, and I felt that they were always there, both occupying the lab place and not making a sound. Lie there to make people feel pity. So I took the time to build a set of Power Amplifier boards to make them sound. Haha, after debugging, it was successful and the effect was good. TI's dedicated audio processing chip is used in the previous stage. For the audio processing capabilitie

Recently contacted the VTune amplifier to do performance optimization. For the average person, often do not want to read so many words to see those instructions. And most want to see is an example, I read the example of amplifier, finally did not find what I want. Very simply, what I want is the performance of the custom time. And after watching the example, I have the impression that from the beginning o

Let's look at the auxiliary theorem: Here, GM refers to the Cross-Guide between the output and the ground transient; rout indicates the output resistance when the input voltage is zero. This is the original statement in the book, but when calculating the formula, we found that the definitions of these two quantities are not completely complete. Is: First, GM is equivalent to cross-export. Remember that it is defined: That is to say, when calculating the equivalent cross-guide, we can intuitive

The first step: empty cans wash clean. Step two: Unplug the pull ring. Step three: Cut off the bottom of the pot along the red line in the picture, and cut it with scissors. Fourth step: Cut the top of the jar along the red line of the figure, don't cut it all off, leave the part of the white mark in the picture. The fifth step: on the opposite side of the white line from the bottom of the cut open cans, as shown in the red lines.

Parameter Interpretation and selection of common op ops, Parameters There are many parameters for Integrated Op-ops. The main parameters are DC and AC indicators, and all chips have limit parameters. This article takes NE5532 as an example to briefly explain each indicator. The following content is not only captured from the NE5532 Data Manual, but also from the network.Limit Parameter It is mainly used to determine the design of the power supply for the op amp (the number of V voltage and the m

Have you noticed the degree to which people are fascinated by mobile devices, especially smartphones? People are using smartphones to surf the Internet, check and write emails, play online games, or update social networks. All these activities, coupled with voice calls, consume battery energy, from power amplifiers (PA) to displays and kernel chipsets, which consume a lot of energy. In the end, the size of the lithium-ion battery can only be increased to ensure that the smartphone is not too hea

In electronic circuits, power supply, amplification, oscillation, and Modulation circuits are called Analog Electronic Circuits because they process and process continuously changing analog signals. 1. Feedback Feedback refers to sending output changes to the input end in some way as part of the input. If the return part and the original input part are subtracted, It is negative feedback. 2. Coupling An amplifier usually has several levels, and the as

blocking, only the front-amplifier with superior performance and low-noise Design circuit can be used to minimize the noise impact. The amplifier with superior performance is the key. The AD855X series is a low-noise, zero-drift, single-power amplifier manufactured by AD. Its superior performance makes it the first choice for many signal detection circuits. 1.

differential amplifier?An integrated, fully differential amplifier is very similar to a standard op amp on a frame.Figure 1 shows a simplified version of the integrated fully differential amplifier. Q1 and Q2 are input differential pairs. In a standard op amp, the output current is removed only from one side of the input differential pair, and the input current
