INTEGRATED CIRCUITS DATA SHEET TDA8576T Class-H high-output voltage level line driver Product specification Supersedes data of 1997 Feb 26 File under Integrated Circuits, IC01 1998 Oct 16 Philips Semiconductors Product specification Class-H high-output voltage level line driver FEATURES Output voltage swing larger than supply voltage High supply voltage ripple rejection Low distortion Low noise ESD protected on all pins. 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.

TDA8576T 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...
