STMicroelectronics TDA7391PD
The TDA7391PD is a bridge class AB audio power amplifier specially intended for car radio high power applications. The high power capability together with the possibility to operate either in differential input mode or single ended input mode makes it suitable for boosters and high end car radio equipment. The exclusive fully complementary output stage and the internal fixed gain configuration drop the external component count.| Part No. | TDA7391PD |
