The TDA7391LVPDTR is a bridge class AB audio power amplifier designed for car radio applications, capable of delivering a maximum output power of 40 W at 4 Oc and 45 W at 3.2 Oc. It operates effectively with a supply voltage as low as 6 V, making it suitable for 'start-stop' and 'e-call' functionalities. The amplifier accepts both single-ended and differential input signals, which enhances its versatility in high-end audio systems. This device features a minimal external component requirement due to its fully complementary output stage and internal fixed gain configuration. It includes a standby function that is CMOS compatible and incorporates several protection mechanisms, including short circuit protection, thermal shutdown, and load dump protection. The TDA7391LVPDTR is packaged in a PowerSO-20 format with tape and reel packing, facilitating automated assembly processes.
