Preamp circuit is TDA1524 from the company Philips. His involvement This circuit can with a minimum of external components to change the volume, balance, treble and bass. Its advantage is that all settings adjustment is performed by changing the voltage on the corresponding pins of the circuit and that for both channels at the same…
TOP261 switch mode power supply smps circuit previous post TDA8920 Class-D Amplifier Circuit power supply The smps power supply of the amplifier, as is indicated must have a few output voltages. This source must be powerful enough to be able to cover the power demands of the terminal degree. The source can be realized as…
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…
MAX5406 The proposed preamplifier is imposing several requirements. The preamp must allow volume control and balance (distribution of volume between channels), then it must allow the correction of the frequency characteristics. These requirements are satisfied by a number of integrated circuits intended for realization of the lna. These circuits, in all cases using to control…
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…
Amlifier Circuit STK428-610 This component is the core of the entire device, therefore, on the choice of the appropriate solution placed particularly great emphasis. In the first project of this work have already been given individual of the working class, which are the switch amplifiers characterized. Between the circuits of SANYO, I chose STK428-610, which…
Digital Preamp Circuit PT2317B. According to the project assignment has to be an amplifier equipped with offsets to low and high tones, and according to the application requirement, it shall be possible to adjust the volume ratio between the left and right channels, thus setting the balance. An essential part is also a volume setting.…
Especially high value capacitors used for power supply, soft start circuit in SMPS circuits 220v line that is used in this circuit one 220V, we also like a lot of trafos is designed to operate directly having a simple structure by regulating. smps high power SMPS PCB design printed circuit board was kept as small…
