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 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…
