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.
