This TDA7384 35 watt car audio power amplifier circuit is designed using TDA7384 class AB Audio Power Amplifier packaged in a Flexiwatt 25 package, designed for high end car radio applications.
Load impedance needed for TDA7384 35 watt car audio power amplifier circuit is 4 ohms (maximum output power of 35W at 4 ohms load impedance is provided using a 13.7V power supply).
The TDA7384’s inputs are ground-compatible and can stand very high input signals (± 8Vpk) without any performances degradation.

The input capacitor is for the low frequency cut-off and the standard value for the input capacitors is 0.1uF ( the cut-off for this value is amount to 16Hz) .
Main features of this car radio amplifier ic are : low distortion , stand by and mute function , output short circuit protection, overrating chip temperature .

Maximum output power is around 35W at 4 ohms load impedance for Vs = 13.7V .
For Vs=13.2V the output power is 22 W with 10% THD and 17W with 0.8W THD on the same load impedance (4 ohms).
