TAS5706A Class D Amplifier was itself the signal processor. From this parts depend all the other elements. Has an impact on the type of power supply, the control method of the type converter. That is why he was first selected DSP processor. There are more firms that produce the processed signal processors whose internal connection…
The power output stage in class D amplifier is implemented using two integrated circuits from the company Texas Instruments – TPA3118D2 for the right and left channel and the TPA3116D2 for the channel of the subwoofer. Stereo channels delivering maximum power output 2×30W into loads of 8 Ω and a subwoofer 100W to a load…
TDA9859 The main part of the preamplifier is an integrated circuit TDA9859, this integrated circuit is controlled via the I2C microprocessor Atmega128. Individual settings of the preamplifier through the keyboard are displayed on the graphical LCD display. Integrated circuit TDA9859 The preamp allows you to adjust the volume level, bass, treble, and balance in a…
Class D Amplifier TDA8927J This integrated circuit includes a terminal switching transistors type DMOS (Double-Diffused MOS), circuits for controlling the transistors and circuits for communication with the control circuit. It is also equipped with a control circuit for detecting the maximum output current and temperature sensor. Further, this circuit is characterized by high efficiency, a…
The block diagram of the integrated circuit TAS5611A As mentioned above, the circuit contains 4 identical channels. The input signal is fed to pin INPUT_X. Signal continues into the feedback filter ANALOG LOOP FILTER and further to the input multiplexer the ANALOG INPUT MUX. In the block ANALOG COMPARATOR MUX occurs to compare the input…
The output stage of the TDA7490 amplifier in class D The core of the end stage class d circuit is TDA7490 from the company STMicroelectronics. The way in which this amplifier works, was discussed above. Here will be dismantled just a function nejdůleţitějších components. On pin 8 generates a modulation signal, or it is possible…
TDA8920 Class-D circuit is to use two circuits TDA8920 in bridge mode connection (BTL). Circuit TDA8920 works with the internal oscillator, whose frequency can be set using the the external elements. The manufacturer recommends that, in the application of multiple circuits in a single device to use for synchronization of circuits external oscillator. Circuit TDA8920…
The design and construction of combos for electric guitar. Work discusses how theories of construction and design blocks combos, so its structure and measuring its parameters and parameters of individual blocks. Bachelor thesis has the aim to get acquainted with the problems of the design of individual parts of the combos, which are the preamp…
The choice of the hi-end-amplifier TDA7293 Power amplifier TDA7293 from the company ST Microelectronics are the most widespread power amplifiers available in our market. Even if his own conception is integrated, contains a number of protections, which greatly contribute to extending the life of the entire amplifier. The main reason for the choice of TDA7293…
The involvement of the preamplifier This is a long-established involvement with tubes type ecc83. This involvement is used by legendary guitar amps Marshall JCM 800 After studying the issue, I decided for the implementation of digital audio amplifier using the circuit TPA3106 D1 of the firm Texas Instruments. The picture sleeve is located on the…
