Package ZIP 25 Pin Type
CD7388CZ overview
The CD7388CZ is a 4 x 41W, Quad Bridge Car Radio Amplifier made by Huajing Microelectronics, supplied in a ZIP 25 Pin Type package. The absolute maximum ratings table on this page lists the 6 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the CD7388CZ pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The UTC CD7388CZ 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 CD7388CZ is suitable for high end car radio applications.
