USING LOW-ESR CAPACITORS
PRINTED-CIRCUIT BOARD (PCB) LAYOUT
Related Documentation
SLOS418D – SEPTEMBER 2003 – REVISED MARCH 2008
Ideally, the device should be held in shutdown when the system powers up and brought out of shutdown once
any digital circuitry has settled. However, if SHUTDOWN is to be left unused, the terminal may be connected
directly to VCC.
Low-ESR capacitors are recommended throughout this application section. A real (as opposed to ideal) capacitor
can be modeled simply as a resistor in series with an ideal capacitor. The voltage drop across this resistor
minimizes the beneficial effects of the capacitor in the circuit. The lower the equivalent value of this resistance
the more the real capacitor behaves like an ideal capacitor.
Because the TPA3007D1 is a class-D amplifier that switches at a high frequency, the layout of the printed-circuit
board (PCB) should be optimized according to the following guidelines for the best possible performance.
Decoupling capacitors—As described in the Power Supply Decoupling section, the high-frequency 0.1-F
decoupling capacitors should be placed as close to the PVCC (pin 9 and pin 16) and VCC (pin 24) terminals
as possible. The BYPASS (pin 22) capacitor, VREF (pin 23) capacitor, and VCLAMP (pin 7) capacitor should
also be placed as close to the device as possible. The large (10
F or greater) bulk power supply decoupling
capacitor should be placed near the TPA3007D1.
Grounding—The VCC (pin 24) decoupling capacitor, VREF (pin 23) capacitor, BYPASS (pin 22) capacitor,
COSC (pin 21) capacitor, and ROSC (pin 20) resistor should each be grounded to analog ground (AGND,
pin 18 and pin 19). The PVCC (pin 9 and pin 16) decoupling capacitors should each be grounded to power
ground (PGND, pin 12 and pin 13). Analog ground and power ground should be connected as a central
ground connection or star ground for the TPA3007D1.
Output filter—The ferrite filter (Figure 16) should be placed as close to the output terminals (pins 10, 11, 14,
and 15) as possible for the best EMI performance. The LC filter (Figure 17) should be placed close to the
ferrite filter. The capacitors used in both the ferrite and LC filters should be grounded to power ground.
For an example layout, refer to the TPA3007D1 Evaluation Module (TPA3007D1EVM) 6.5W Mono Class-D
Audio Power Amplifier User's Guide, TI literature number SLOU164, available on the TI Internet site www.ti.com.
For further layout information, refer to Layout Guidelines for TPA300x Series Parts Application Report, TI
literature number SLOA103, also available on the TI Internet site.
