4 / 13 page APPLICATIONS SUGGESTIONS (See Test and Application Circuit) The recommended values of the external components are those shown on the application circuit. Differ- ent values can be used; the following table can help the designer. Comp. Value Purpose Larger Than Smaller Than R1 22K Ω (*) Input Impedance Increase of Input Impedance Decrease of Input Impedance R2 560 Ω Closed Loop Gain set to 32dB (**) Decrease of Gain Increase of Gain R3 22K Ω (*) Increase of Gain Decrease of Gain R4 22K Ω (*) Input Impedance @ Mute R5 22K Ω Stand-by Time Constant R6 4.7 Ω Frequency Stability Danger of oscillations Danger of oscillations C1 1 µF Input DC Decoupling Higher Low-frequency cut-off C2 10 µF Feedback DC Decoupling Higher Low-frequency cut-off C3 10 µF Stand-by Time Constant C4 0.100 µF Frequency Stability Danger of Oscillations C5, C6 1000 µF Supply Voltage Bypass (*) R1 = R3 = R4 for POP optimization (**) Closed Loop Gain has to be ≥ 30dB Figure 1: Output Power vs. Supply Voltage Figure 2: Distortion vs. Output Power TYPICAL CHARACTERISTICS TDA2052 4/13 |
