High Performance Class-D Speaker Amplifier Series

7W+7W Class-D

Speaker Amplifier for Analog Input

BD5427MUV

No.09075EAT07

●Overview

BD5427MUV is a 7W + 7W 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 80% (7W + 7W 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 14W. 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 80% (7W + 7W output with 8Ω load), which is the highest grade in the industry and low heat-generation.

2) Driving a lowest rating load of 6Ω is allowed.

3) Pop noise upon turning power on/off and power interruption has been reduced.

4) High-quality audio muting is implemented by soft-switching technology.

5) 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.

6) A master/slave function allowing synchronization of multiple devices reduces beat noises.

7) Adjustment of internal PWM sampling clock frequencies (250kHz to 400kHz) allows easy protective measures against

unwanted radio emission to AM radio band.

8) A compact back-surface heat radiation type power package is employed.
