BD5426EFS - Class-D Speaker Amplifier

General 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.

Key Features

  • ) 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) Hi.

Middle Power Class-D Speaker Amplifiers Analog Input / BTL Output Class-D Speaker Amplifier BD5426EFS No.10075EBT05 ●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).
