Product Summary
The TPA3100D2RGZR is a 20-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. The TPA3100D2RGZR can drive stereo speakers as low as 4 W. The high efficiency of the TPA3100D2RGZR, 92%, eliminates the need for an external heat sink when playing music. The gain of the amplifier is controlled by two gain Auto Recovery Feature select pins. The gain selections are 20, 26, 32, 36dB. The outputs are fully protected against shorts to GND, VCC, and output-to-output shorts with an auto Package recovery feature and monitor output. The applications of the TPA3100D2RGZR include Televisions.
