.ti. HLQFP TPA3106D1 SLOS516C - OCTOBER 2007 - REVISED AUGUST 2010 40-W MONO CLASS-D AUDIO POWER AMPLIFIER Check for Samples: TPA3106D1 Features 1 - 40-W Into an 8-Ω Load From a 25-V Supply - Operates From 10 V to 26 V - Efficient Class-D Operation Eliminates the Need for Heat Sinks - Four Selectable, Fixed Gain Settings - Differential Inputs - Thermal and Short-Circuit Protection With Auto Recovery Feature - Clock Output for Synchronization With Multiple Class-D Devices - Surface Mount 7×7, 32-pin HLQFP Package APPLICATIONS - Televisions - Powered Speakers DESCRIPTION The TPA3106D1 is a 40-W efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. The TPA3106D1 can drive stereo speakers as low as 4Ω. The high efficiency, ~92%, of the TPA3106D1 eliminates the need for an external heat sink when playing music. The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36 dB. The outputs are fully protected against shorts to GND, VCC, and output-to-output shorts with an auto recovery feature and monitor output. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet....
