Datasheet Class-AB Speaker Amplifier Series 1.2 W Monaural Speaker Amplifier for Automotive BD783xxEFJ-M Series (Including products under development) General Description BD783xxEFJ-M Series are Class-AB monaural speaker amplifiers designed for automotive. Class-AB amplifiers have no requirements for care about EMI noise. Adopting power package HTSOP-J8 achieves high output power. Low quiescent current can reduce battery consumption. Shutdown current is also very low (0.1 µA Typ) and pop noise level when switching to shutdown is very small, so this device is suitable for applications in which the mode often changes between “shutdown state” and “active state”.
