Product specification
Class-H high-output voltage level line
driver
TDA8574
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 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.
