... TDA8574 DIP16 plastic dual in-line package; 16 leads (300 mil) 1998 Oct 16 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 ...
