STMicroelectronics Class-D Audio Amplifier Demonstration Boards

STMicroelectronics Class-D Audio Amplifier Demonstration Boards

STMicroelectronics Class-D Audio Amplifier Demonstration Boards are designed for the evaluation of class-D audio amplifiers (TDA7491HV, TDA7491LP, TDA7491MV, TDA7491P, TDA7492, and TDA7498E) from STMicroelectronics. Each demonstration board is designed for a specific device and has it's own features and benefits. Due to the high efficiency of these devices, each is able to dissipate the generated heat during use with a reasonably small heat sink or in some cases, no heat sink at all.

STMicroelectronics STEVAL-CCA042V1 Class-D Audio Amplifier Demonstration Board is designed for the TDA7491HV high-power dual BTL class-D audio amplifier. Thanks 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 configuration of the amplifier 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.
