Application circuit of TDA1524

TDAls24 and LM1036 belong to the same type of product. They only differ in some parameters. The maximum
output voltage of TDA1524 is as high as 3V and the input voltage is 2.5V, which is higher than that of LM1036. However, the noise of TDA1524 is higher,
and it can reach 310∥.
    TDA1524 is a dual in-line 18-pin package, and its application circuit is shown in Figure 4-29. When
    TD A15 24 is used, when the load capacitance exceeds
    - 20pF, the output must be connected in series with a 200n resistor;
to increase the bass boost, you can connect pins 5(14) and 6(13) The capacitor is changed to a double-pole low-pass filter,
as shown in Figure 4-29 (b); if you want to reduce the amount of bass improvement, you can connect a resistor and
capacitor , the function of the capacitor is to disconnect the DC path. The smaller the resistance value, the lower the boost amount, as shown in Figure (c);
if you want to reduce the treble boost amount, you can connect a resistor in series with C9 (ClO), such as As shown in Figure (d), the larger the resistance value,
the lower the amount of improvement.
    In order to increase the signal processing capabilities. A DC negative feedback network can be added, as shown in Figure 4-29 (e).
