... Philips Semiconductors 2 120 W class-D power amplifier 16 APPLICATION INFORMATION 16.1 BTL application When using the power amplifier in a mono BTL application (for more output power), the inputs of both channels must be connected in parallel; the phase of one of the inputs must be inverted; see Fig.5. In principle the loudspeaker can be connected between the outputs of the two single-ended demodulation filters ...

... Philips Semiconductors 2 120 W class-D power amplifier 16.5 Heatsink requirements Although the TDA8924 is a class-D amplifier a heatsink is required. Reason is that though efficiency is high, the output power is high as well, resulting in heating up of the device. The relation between temperatures, dissipation and thermal behaviour is given below. ...

... Notes 1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note ” (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the “ ...
