Middle Power Class-D Speaker Amplifier series
15W+15W
Class D Speaker Amplifier for Digital Input
BD5452AMUV
●General Description
BD5452AMUV 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
15W+15W. This IC employs state-of-the-art Bipolar,
CMOS, and DMOS (BCD) process technology. With this
technology, the IC can achieve high efficiency. 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 30W. This product satisfies both needs for drastic
downsizing, low-profile structures and many function,
high quality playback of sound system.
●Features
This IC has one system of digital audio interface.(I2S
format, SDATA: 16 / 20 / 24bit, LRCLK: 32kHz /
44.1kHz / 48kHz, BCLK: 64fs(fixed), MCLK: 256fs /
512fs)
Low supply current at RESET mode.
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.
Eliminate large electrolytic-capacitors for high
performance of Power Supply Rejection.
Power Limit Function. (at RL =8Ω, 10W /5W /OFF)
Available for Monaural mode.
Within the wide range of the power supply voltage, it
is possible to operate in a single power supply. (10 to
18V)
It contributes to miniaturizing, making to the thin type,
and the power saving of the system by high efficiency
and low heat.
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.
This IC 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, (MCLK, BCLK, LRCLK)
Small package (VQFN032V5050 package)
contributes to reduction of PCB area.
