PRODUCTION DATA.
NOTE
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
These typical connection diagrams highlight the required external components and system level connections for proper operation of the device in several popular use cases. Each of these configurations can be realized using the evaluation modules (EVMs) for the device. These flexible modules allow full evaluation of the device in the most common modes of operation. Any design variation can be supported by TI through schematic and layout reviews. Visit the E2E Forum at www.e2e.ti.com for design assistance and join the audio amplifier discussion forum for additional information.
See Figure 16 for application schematic. In this application, differential PWM inputs are used with AD modulation from the PWM modulator (TAS5558). AD modulation scheme is defined as PWM(+) as opposite polarity from PWM(–).
Table 5 lists the design parameters of Figure 16.
PARAMETER | VALUE |
---|---|
Digital regulator supply | 12 V |
Full-bridge power supply | 12 V to 38 V |
PWM modulator | TAS5558 |
Output filters | Inductor-capacitor lowpass filter |
Speaker | 2.5 Ω minimum |
Using Figure 16 as a guide, integrate the hardware into the system schematic.
Following the recommended component placement, schematic layout and routing given in Layout Example, integrate the device and its supporting components into the system PCB file.
See Figure 19 for application schematic. In this application, four single-ended PWM inputs are used with AD modulation from the PWM modulator such as the TAS5558. AD modulation scheme is defined as PWM(+) is opposite polarity from PWM(–). The single-ended (SE) output configuration is often used to drive four independent channels in one TAS5622A device.
