Description :

25W four-channel (BTL) audio amplifier circuit. The YD-7388 is a class AB Audio Power Amplifier. It
allows a rail to rail output voltage swing with no need of bootstrap capacitors for the fully complementary PNP/NPN output configuration. The YD7388 is suitable for high end car radio applications.

The circuit characteristics are as follows:
Output power: Po = 25W × 4 (Vcc = 14.4V, BTL, RL = 4Ω, THD = 10%);

Features
