BD5424EFS Datasheet (Rohm) - Analog Input / BTL Output Class-D Speaker Amplifier

BD5424EFS, Analog Input / BTL Output Class-D Speaker Amplifier

BD5424EFS is a 20W + 20W stereo class-D power amplifier IC, developed for space-saving and low heat-generation applications such as low-profile TV sets.

The IC employs state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology that eliminates turn-on resistance in the output power stage and i

BD5424EFS Features

* 1) A high efficiency of 91% (10W + 10W output with 8Ω load), which is the highest grade in the industry and low heat-generation. 2) An output of 20W + 20W (17V, with 8Ω load) is allowed without an external heat radiator. 3) Driving a lowest rating load of 3.6Ω is allowed. 4) Pop noise upon turning p
