STEVAL-CCA044V1, DEMO BOARD, CLASS-D AUDIO AMPLIFIER
Demonstration board is designed for the TDA7498E high power 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 a heatsink. Jumpers on the board allow the configuration of the amplifier in order to verify all the features as single-ended or differential input, fixed gain settings. Microswitches are also provided to enable the standby and mute functions.
