7 / 9 page Component Recommended value Purpose Larger than recommended value Smaller than recommended value C1 2.2 µF Input DC decoupling Noise at switch-on, switch-off C2 470 µF Ripple rejection. Degradation of SVR. C3 0.1 µF Supply by passing. Danger of oscillation. C4 1000 µF Output coupling. Higher low frequency cutoff. C5 0.1 µF Frequency stability. Danger of oscillation at high frequencies with inductive loads. R1 (Gv -1) • R2 Setting of gain. (*) Increase of drain current. R2 2.2 Ω Setting of gain and SVR. Degradation of SVR. R3 1 Ω Frequency stability. Danger of oscillation at high frequencies with inductive loads. PRACTICAL CONSIDERATIONS Printed circuit board The layout shown in Fig. 2 is recommended. If different layouts are used, the ground points of input 1 and input 2 must be well decoupled from the ground of the output through which a rather high current flows. Assembly suggestion No electrical insulation is needed between the package and the heat-sink. Pin length should be as short as possible. The soldering temperature must not exceed 260 °C for 12 seconds. Application suggestions The recommended component values are those shown in the application circuits of Fig. 1. Different values can be used. The following table is intended to aid the car-radio designer. (*) The closed loop gain must be higher than 26dB. 7/9 TDA2008 |
