STEVAL-CCA040V1: 10W x4 @ 4Ω, 8 ~ 22V in, ClassAB

Summary

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.

These amplifiers are used for high-quality sound applications. Each amplifier has integrated short-circuit and thermal protection and diagnostic functions. Two amplifiers can be paired up for applications requiring high power output.
