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.
