General Description

Features

^z8V to 25.5V Input Supply Range

The RT9108Nis a 15W per channel, high efficiency Class

Dstereo audio amplifier for driving Bridge Tied Load (BTL)

speakers. The RT9108N 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 two gain select pins.

The outputs are fully protected against shorts to GND,

PV_CC, and output to output with an auto recovery feature

and monitored output.
