TDA7491LP评估套件评价tda7491lp双BTL D类音频功率放大器,并且它的效率高在没有任何散热片条件下也具有散热功能。The STEVAL-CCA029V1 demonstration board is designed for the evaluation of the TDA7491LP dual BTL class-D audio amplifier.Due to its high efficiency, the device, assembled in the PSSO36 (slug-down) package, is capable of dissipating heat without any heatsink. Jumpers on the board allow the configuration of the amplifier in order to verify all the features as single-ended or differential inputs, fixed gain settings. Microswitches are also provided to enable the standby and mute functions.Key Features
