Board and Components layout of the Circuit of Fig.1 (1 : 1 scale). 4/7 TDA2007A APPLICATION SUGGESTION The recommended values of the components are those shown on application circuit of fig.1. Different values can be used ; the following table can help the designer. Component R1, R3 R2 and R4 R5 and R6 Recommended value 1.3K 18 1 Purpose Close Loop Gain Setting (*) Frequency stability Larger Than Increase of Gain Decrease of Gain Danger of Oscillation at High Frequency with Inductive Load High Turn-on Pop Higher Low Frequency Cutoff. Increase of Noise Degradation of SVR Smaller Than Decrease of Gain Increase of gain C1 and C2 2.2µF Input DC Decoupling High Turn-on Delay C3 22µF Ripple Rejection Better SVR Increase of the Switch-on Time C6 and C7 C8 and C9 220µF 0.1µF Feedback Input DC Decoupling Frequency Stability Danger of Oscillation (*) The closed loop gain must be higher than 26 dB.
