The RT9116 is a 10W per channel, high efficiency Class D 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.

The RT9116 is available in the WQFN-28L 4x5 package.
