uitable for Walkman power connection, or for the transformation of low-powered computer speakers. TDA1521A using nine-pin single in-line plastic package, with output power, two-channel gain difference is small, the speaker no switch machine impact sound and reliable thermal overload and short circuit protection features. TDA1521A When both with positive and negative power supply can also be a single power supply, the circuit schematic are shown in Figure 1 (a), (b) dual power supply, eliminating the need for two audio output capacitance, high bass sound better. Single supply, power supply filter capacitor should be as close to the power terminal of the integrated circuit, the internal circuit to avoid self-excited. Must give manifold mounted on a heat sink to power test tone production, or easy to damage the manifold. Radiating plate can not be less than 200 100 2mm3.
