Class-AB Speaker Amplifier Series

1.2 W

Monaural Speaker Amplifier for Automotive

BD783xxEFJ-M Series (Including products under development)

General Description

Key Specifications

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”.
