Middle Power Class-D Speaker Amplifier series
20W+20W
Full Digital Speaker Amplifier
with built-in DSP
BM5480MUV
PERFECT PURE
Bass+
●General Description
BM5480MUV is a Full Digital Speaker Amplifier with
built-in DSP (Digital Sound Processor) designed for
Flat-panel TVs in particular for space-saving and
low-power consumption, delivers an output power of
20W+20W. This IC employs 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. 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.
●Key Specifications

●Package
VQFN48V7070P
W(Typ.) x D(Typ.) x H(Max.)
7.00mm x 7.00mm x 1.00mm
●Features
■ This IC includes the DSP (digital sound processor)
for Audio signal processing for Flat TVs.
P2Bass+( pseudo bass), 16 Band P-EQ,
Level DRC, 2 Band DRC, Surround, etc.
■ This IC has one input systems of digital audio
interface. (No needs of Master Clock)
- I2S / LJ / RJ format
- LRCLK: 32k/44.1k/48KHz
- BCLK: 32fs / 48fs / 64fs
- SDATA: 16 / 20 / 24bit
■ With wide range of power supply voltage.
■ The monaural output that can reduce the number of
external parts can be used.
■ With high efficiency and low heat dissipation
contributing to miniaturization, slim design, and also
power saving of the system.
■ Eliminates pop-noise generated during the power
supply on/off. High quality muting performance is
realized by using the soft-muting technology.
■ This IC is built-in with various protection functions
for highly reliability design.
- High temperature protection
- Over voltage protection, Under voltage protection
- Output short protection
- DC voltage protection
- Clock stop protection
■ Small package
