SLOS498B September 2006 – September 2015 TPA2006D1
PRODUCTION DATA.
Place all the external components close to the TPA2006D1 device. The input resistors need to be close to the TPA2006D1 device input pins so noise does not couple on the high impedance nodes between the input resistors and the input amplifier of the TPA2006D1 device. Placing the decoupling capacitor, CS, close to the TPA2006D1 device is important for the efficiency of the class-D amplifier. Any resistance or inductance in the trace between the device and the capacitor can cause a loss in efficiency.
