High Efficiency 35W x 4CH Amplifier IC
The TDA7454 is a BCD technology QUAD BRIDGE type of car radio amplifier IC in the Flexiwatt 25 package specially intended for car radio applications. Among the features, its superior efficiency performance coming from the internal exclusive structure, makes it the most suitable device to simplify the thermal management in high power sets. The dissipated output power under average listening condition is reduced up to 50% when compared to the level provided by conventional class AB devices.
