Description
This board is a general-purpose developmant platform for all applications based on the TS4962M mono class D audio amplifier. The TS4962M is a monolithic fully-differential input/ output class D power amplifier. It also includes a common-mode feedback loop that controls the output bias value to average it at VCC/2 for any DC common mode input voltage. This allows the device to always have a maximum output voltage swing, and consequently maximizes the output power. Moreover, as the load is connected differentially compared to a single-ended topology, the output is four times higher for the same power supply voltage.
