High Performance Class-D Speaker Amplifier Series 7W+7W Class-D Speaker Amplifier for Analog Input BD5427EFS ●Overview BD5427EFS 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 8 Ω load). 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 8 Ω load), which is the highest grade in the industry and low heat- generation. 2) Driving a lowest rating load of 6 Ω 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.
