Product specification

TDA8576T

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.

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.
