STEVAL-CCA001V1
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.
