Description

The STEVAL-CCA040V1 demonstration board is

designed using the STA540SAN dual/quad class

AB power amplifier assembled in a Clipwatt 15

package.

Thanks to the high flexibility offered by the

STA540SAN device, it is possible to configure the

board to realize a stereo dual bridge (BTL)

amplifier, a four channel single-ended (SE)

amplifier or a 2.1 channel amplifier composed of a

stereo BTL + mono BTL amplifier.
