Details are subject to change without notice. 1/10 TDA7381 DESCRIPTION (continued) Thanks to the fully complementary PNP/NPN output configuration the TDA7381 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets. AB...
