    The TDAA provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates a short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A conventional thermal shut-down system is also included. Commonly, these loudspeaker systems divide the audio spectrum into two or three bands. To maintain a flat frequency response over the Hi-Fi audio range the bands covered by each loudspeaker must overlap slightly. Imbalance between the loudspeakers produces unacceptable results therefore it is important to ensure that each unit generates the correct amount of acoustic energy for its segmento of the audio spectrum. In this respect it is also important to know the energy distribution of the music spectrum to determine the cutoff frequencies of the crossover filters see Figure As an example a W three-way system with crossover frequencies of Hz and 3kHz would require 50W for the woofer, 35W for the midrange unit and 15W for the tweeter. Figure 19 : Active Power Filter Both active and passive filters can be used for crossovers but today active filters cost significantly less than a good passive filter using air cored inductors and non-electrolytic capacitors. In addition, active filters do not suffer from the typical defects of passive filters: - power less - increased impedance seen by the loudspeaker lower damping - difficulty of precise design due to variable loudspeaker impedance. Obviously, active crossovers can only be used if a power amplifier is provided for each drive unit. This makes it particularly interesting and economically sound to use monolithic power amplifiers.

    Even if with a regulated supply higher output power can be obtained VS is constant in all working conditions , the additional cost and power dissipation do not usually justify its use.

    Using non-regulated supplies, there are fewer designe restriction. In fact, when signal peaks are present, the capacitor filter acts as a flywheel supplying the required energy.

    In average conditions, the continuous power supplied is lower. Different values can be used. The Table 2 can help the designer. This function can be considered as being peak power limiting rather than simple current limiting.

    It reduces the possibility that the device gets damaged during an accidental short circuit from AC output to ground. An overload on the output even if it is permanent , or an above limit ambient temperature can be easily supported since the Tj cannot be higher than o C.

    The heatsink can have a smaller factor of safety compared with that of a conventional circuit.

    There is no possibility of device damage due to high junction temperature. If for any reason, the junction temperature increases up to o C, the thermal shut-down simply reduces the power dissipation and the current consumption. Table 2 Comp. V5 90 typ.

    The circuit is most useful with high resolution displays that have OSD, and its function are available for each channel, including OSD blanking, wide-band amplification, contrast control.

    This IC can apply the broad application because of low noise and distortion. Low noise and low distortion.

    PCM :. Stereo Audio Codec.

    Otherwise your IC will be burned out. So be carefull about this. It gives about 10watt RMS as the output power which is quite satisfying for a low budget mini audio amplifier. And the input voltage level is around 8vv.

    Iused 12v-3A here. And the most important thing is it requires the input voltage biasing. And a ground pin also. But if you modify the circuit diagram for single power source then it'll be okay for you.

    Then you can go wih the single power supply. I hope I gave you some important tips about making TDA amps.
