10W Stereo Class-D Speaker Driver Amplifier

General Description

Features

^8V to 17V Input Supply Range

The RT9116 is a 10W per channel, high efficiency ClassD

stereo audio amplifier for driving bridge tied load (BTL)

speakers. The RT9116 can drive stereo speakers with load

as low as 4Ω. Its high efficiency eliminates the need for

an extra heat sink when playing music. The gain of the

amplifier can be controlled by gain select pins. The outputs

are fully protected against shorts to GND, PVCC, and

output to output with an auto recovery feature and monitored

output.
