STMicroelectronics TDA7391LV 35W Bridge Car Radio Amplifier Datasheet
The TDA7391LV is a bridge class AB audio power amplifier specifically intended for car radio high power applications. It features a high power capability of up to 40W into a 4Ω load and supports low voltage operation down to 6V, making it suitable for 'start-stop' battery profiles. The device includes a fully complementary output stage with an internal fixed gain of 30dB, eliminating the need for external bootstrap capacitors or boucherot cells.
