Description
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.
