Component Location
Place all the external components very close to the TPA2010D1. The input resistors need to be very close to
the TPA2010D1 input pins so noise does not couple on the high impedance nodes between the input resistors
and the input amplifier of the TPA2010D1. Placing the decoupling capacitor, C
S
, close to the TPA2010D1 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.
Trace Width
Recommended trace width at the solder balls is 75
μ
m to 100
μ
m to prevent solder wicking onto wider PCB
traces. Figure 34 shows the layout of the TPA2010D1 evaluation module (EVM).
For high current pins (V
DD
, GND V
O+
, and V
O
) of the TPA2010D1, use 100-
μ
m trace widths at the solder balls
and at least 500-
μ
m PCB traces to ensure proper performance and output power for the device.
For input pins (IN, IN+, and SHUTDOWN) of the TPA2010D1, use 75-
μ
m to 100-
μ
m trace widths at the solder
balls. IN and IN+ pins need to run side-by-side to maximize common-mode noise cancellation. Placing input
resistors, R
IN
, as close to the TPA2010D1 as possible is recommended.
