2 / 29 page TS4984 Typical Application 2/29 1 Typical Application Figure 1 shows a schematic view of a typical audio amplification application using the TS4984. Table 1 describes the components used in this typical application. Figure 1: Typical application schematic Table 1: External component descriptions Components Functional Description RIN L,R Inverting input resistors which sets the closed loop gain in conjunction with Rfeed. These resistors also form a high pass filter with CIN (fc = 1 / (2 x Pi x RIN x CIN)). CIN L,R Input coupling capacitors which blocks the DC voltage at the amplifier input terminal. RFEED L,R Feedback resistors which sets the closed loop gain in conjunction with RIN. CS Supply Bypass capacitor which provides power supply filtering. CB Bypass pin capacitor which provides half supply filtering. AV L, R Closed loop gain in BTL configuration = 2 x (RFEED / RIN) on each channel. 1 2 12 16 15 Bias 3 AV = -1 Bypass L Standby + - + - AV = -1 + - + - 10 9 8 7 11 Bypass R VO-L VO+L VO-R VO+R IN-L IN+L IN+R IN-R U1 TS4984 VCC Cs 1u 1 2 3 VCC Rin-L Cin-L Input L GND Rin-R Cin-R Input R GND Cfeed-L Rfeed-L Cfeed-R Rfeed-R Cb 1u Neg.
