NXP Semiconductors TDA8574
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. With a supply voltage of 9 V the output voltage swing over the load will be 14 V (peak-to-peak).| Part No. | TDA8574 |

● ESD protected on all pins.
GENERAL DESCRIPTION
Due to the class-H voltage lifting principle the voltage swing over the load is more than the supply voltage.

TDA8574 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.
