High Performance Class-D Speaker Amplifier Series  
20W+20W Class-D  
Speaker Amplifier for Analog Input  
BD5424EFS  
No.09075EAT04  
●Overview  
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 internal loss due to line resistances up to an  
ultimate level. With this technology, the IC has achieved high efficiency of 91% (10W + 10W output with 8Ω load), which is  
the top class in the industry. The IC, in addition, employs a compact back-surface heat radiation type power package to  
achieve low power consumption and low heat generation and eliminates necessity of installing an external radiator, up to a  
total output of 40W. This product satisfies both needs for drastic downsizing, low-profile structures and powerful, high-quality  
playback of the sound system.  
●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 power on/off and power interruption has been reduced.  
5) High-quality audio muting is implemented by soft-switching technology.  
6) An output power limiter function limits excessive output to speakers.  
7) High-reliability design provided with built-in protection circuits against high temperatures, against VCC shorting and  
GND shorting, against reduced-voltage, and against applying DC voltage to speaker.  
8) A master/slave function allowing synchronization of multiple devices reduces beat noises.  
9) Adjustment of internal PWM sampling clock frequencies (350kHz to 500kHz) allows easy protective measures against  
unwanted radio emission to AM radio band.  
10) A compact back-surface heat radiation type power package is employed.
