LINEAR INTEGRATED CIRCUIT
4 X 41W QUAD BRIDGE CAR
RADIO AMPLIFIER
DESCRIPTION
The UTC TDA7388 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 UTC TDA7388 is suitable for high end car radio
applications.
