80 / 97 page  Table 9-1. Recommended External Components (continued) COMPONENT DESCRIPTION SPECIFICATION MIN TYP MAX UNIT C4 PVDD Decoupling Capacitor Type X7R Capacitance, 20% Tolerance 100 nF Rated Voltage 30 V C5 AVDD Decoupling Capacitor Type X7R Capacitance, 20% Tolerance 4.7 µF Rated Voltage 6 V C6 DREG Decoupling Capacitor Type X7R Capacitance, 20% Tolerance 1 µF Rated Voltage 6 V C7 IOVDD Decoupling Capacitor Type X7R Capacitance, 20% Tolerance 1 µF Rated Voltage 6 V C8, C9 Bootstrap Capacitors Type X7R Capacitance, 20% Tolerance 100 nF Rated Voltage 6 V Lf1, Lf2 (optional) Optional EMI filter inductors. These are not recommended as it degrades THD+N performance. The TAS2780 device is a filter-less Class-D and does not require these bead inductors. Impedance at 100MHz 120 Ω DC Resistance 0.095 Ω DC Current 7 A Cf1, Cf2 (optional) Optional EMI filter capacitors (must use Lf2, Lf3 if Cf1, Cf2 used) Capacitance 1 nF RF Filter resistor for noise reduction Resistor, 20% Tolerance 1 kΩ CF Filter capacitor for noise reduction Capacitance, 20% Tolerance 10/RF(kΩ) nF Rated Voltage 30 V 9.3 Design Requirements For this design example, use the parameters shown in Section 9.2. Table 9-2. Design Parameters DESIGN PARAMETER EXAMPLE VALUE Audio Input Digital Audio, I2S Current and Voltage Data Stream Digital Audio, I2S Mono or Stereo Configuration Mono Max Output Power at 1% THD+N, RL = 4 Ω 25 W 9.4 Detailed Design Procedure 9.4.1 Mono/Stereo Configuration In applications the device is assumed to be operating in mono mode. See Section 8.3.1 for information on changing the I2C address of the TAS2780 to support stereo operation. Mono or stereo configuration does not impact the device performance. 9.4.2 EMI Passive Devices The TAS2780 supports spread spectrum to minimize EMI. It is allowed to include passive devices on the Class-D outputs. The passive devices Lf1, Lf2, Cf1 and Cf2 from Figure 9-1 have recommended specifications provided in Table 9-1. The passive devices of the output filter have to be properly selected to maintain the stability of the amplifier. See Section 8.4.5 for details. 9.5 Application Curves At TA = 25 0C, fSPK_AMP = 384 kHz, input signal fIN = 1kHz - Sine, Load = 4Ω + 15μH, unless otherwise noted.
