ESD protected on all pins.
GENERAL DESCRIPTION
The TDA8574(T) is a two channel class-H high-output
voltage line driver for use in car audio applications.
The line driver behaves as a non-inverting amplifier with a
gain of 8 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
14 V (peak-to-peak).
The TDA8574 is available in a DIP16 package and the
TDA8574T 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 TDA8574(T) class-H high-output
level line driver. The high-output level of TDA8574(T)
enables a reduction of the gain of the power amplifier
resulting in an improvement of the power amplifier
performance.
