For filtering lower-frequency noise signals, a 10 mF or greater capacitor (CS2) placed near the audio power amplifier would also help, but it is not required in most applications because of the high PSRR of this device. Typically, the smaller the capacitor's case size, the lower the inductance and the closer it can be placed to the TPA2011D1.
