製品概要
概要
The STA540SAN contains four single-ended, class-AB audio amplifiers assembled in a Clipwatt15 package.
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.
