General Description: The TDA8576T is a two channel class-H high-output  voltage line driver for use in car audio applications.  The line driver operates as a non-inverting amplifier with a  gain of 6 dB and a single-ended output. Due to the class-H  voltage lifting principle the voltage swing over the load is  more than the supply voltage.  With a supply voltage of 9 V the output voltage swing over  the load will be more than 14 V (peak-to-peak).  The TDA8576T is available in a SO16 package.  Line drivers are necessary in car audio systems in which  the power amplifiers are driven by long cables.  The signal-to-noise ratio of these car audio systems is  improved by using the TDA8576T class-H high-output  level line driver. The high-output level of TDA8576T  enables a reduction of the gain of the power amplifier  resulting in an improvement of the power amplifier  performance. Circuit Diagram: Class-...
