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). In addition, the IC is packaged in a compact reverse heat radiation type power package to achieve low power consumption and low heat generation and eliminates necessity of external heat-sink up to a total output power of 40W. This product satisfies both needs for drastic downsizing, low-profile structures and many function, high quality playback of sound system.
Features
1) BD5446EFV has two system of digital audio interface. (I2S/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. (20~34dB / 2dB step)
5) It has the output power limitation function that can be adjusted to an
arbitrary output power.
6) The decrease in sound quality because of the change of the power supply
voltage is prevented with the feedback circuitry of the output. In addition, a
low noise and low distortion are achieved.
7) It provides with the best stereo DAC output for the headphone usage. As a
result, the output of the selection of the digital input in two systems is
possible.
8) Eliminates pop noise generated when the power supply goes on/off, or when
the power supply is suddenly shut off. High quality muting performance is
realized by using the soft-muting technology.
9) BD5446EFV is a highly reliable design to which it has various protection
functions. (High temperature protection, Under voltage protection, Output
short protection, Output DC voltage protection and Clock stop protection)
Applications
Flat Panel TVs (LCD, Plasma), Home Audio, Desktop PC, Amusement equipments, Electronic Music equipments, etc.,
