General Description

BD5446EFV is a Class D Speaker Amplifier designed for Flat-panel TVs in particular for space-saving and low-power consumption, delivers an output power of 20W+20W.

This 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 can achieve high efficiency of 87% (10W+10W output with 8Ω load).

Key Features

  • ) BD5446EFV has two system of digital audio interface. 2 (I S/LJ format, SDATA: 16 / 20 / 24bit, LRCLK: 32kHz / 44.1kHz / 48kHz, BCLK: 64fs (fixed), SYS_CLK: 256fs (fixed)) 2) Within the wide range of the power supply voltage, it is possible to operate in a single power supply. (10~26V) 3) It contributes to miniaturizing, making to the thin type, and the power saving of the system by high efficiency and low heat. 4) S/N of the system can be optimized by adjusting the gain setting among 8 steps.
