TDA8574
Datasheet
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.
Features
- Output voltage swing larger than supply voltage
- High supply voltage ripple rejection
- Low distortion
- Low noise
- ESD protected on all pins.
