RT9116
10W Stereo Class-D Speaker Driver Amplifier
General Description
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.
