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.

ducThe best audio performance is obtained with the configuration where each speaker has its
roown DC blocking capacitor. If the application allows a little degradation of the spatial image it
Pis possible to connect a couple of speakers with only one low-value DC blocking capacitor.
