MTDA7385 

4CH. 4X25W Original ST IC Power Amplifier DIY KIT  

Assembled or KIT

Description (From ST Data Sheet)

The TDA7381 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed for high end car radio applications. 

Based on a fully complementary PNP/NPN configuration, the TDA7381 allows a rail to rail output voltage swing with no need of bootstrap capacitors. 

The extremely reduced boundary components count allows very compact sets. 

The on-board clipping detector simplifies gain compression operations. 

The fault diagnostics makes it possible to detect mistakes during car radio assembly and wiring in the car.
