Function : 4 x 41W, Quad Bridge Car Radio Amplifer
Pacakge : ZIP 25 Pin Type
Manufactures : Huajing Microelectronics
The device 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 CD7388CZ is suitable for high end car radio applications.
1. High Output Power@ VCC=14.4V, f=1kHz, RL=4 Ω: (1) 4 x 41W Max. (2) 4 x 25W @THD=10% (3) Rail to rail output voltage swing
Protections 1. Output short circuit to GND, to VS, across the load 2. Very inductive loads 3. Overrating chip temperature with soft thermal limiter 4. Load dump voltage 5. Fortuitous open GND 6. Output DC offset detector 7. Reversed battery 8. ESD
