●Description
BD5426EFS is a 10W + 10W 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 87% (9W + 9W output with 8Ω 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 20W. 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 87% (9W + 9W output with 8Ω load), which is the highest grade in the industry and low heat-generation. 2) An output of 10W + 10W (13V, with 8Ω load) is allowed without an external heat radiator. 3) Driving a lowest rating load of 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 provid...
