ALC5640-VB
Datasheet
1. General Description
The ALC5640 is a high performance, low power, dual I2S interface audio CODEC. Dual I2S interface can
connect to different devices and let the ALC5640 to be an Audio Hub. Each device can pass through the
Audio Hub and then perform as input or output application. Asynchronous Sample Rate Converter
(ASRC) provides independent and asynchronous connections to different processors, such as an
application processor, baseband processor or wireless transceiver(BT).
Stereo Class-D speaker amplifiers provide 1.5W per channel into or 2.5W per channel into 4Ω with a
5V supply, with excellent PSRR and low EMI. A mono differential earpiece amplifier is also provided,
providing output from any DAC or Analog-in.
The ALC5640 features an ultra low power cap-free headphone amplifier. It consumes only less than
5mW power during playback, providing mobile system longer battery life under headphone listening
mode.
The integrated DRC(Dynamic Range Controller) and 7-band parametric Equalizer provide further digital
sound processing capability of audio playback paths. The DRC in ALC5640 continuously monitors the
DAC output level. When the power level is low, it increases the input signal gain to make it sound louder.
At the same time, if a peaking signal is detected, it autonomously reduces the applied gain to avoid hard
clipping. It ensures the maximum/consistent signal amplitude without producing audio clipping and
speaker damage. The 7-band parametric Equalizer contains 7 independent filters with programmable gain,
center frequency and bandwidth to tailor the frequency characteristics of embedded speaker system
according to user preferences.
For microphone recording, the DRC in ALC5640 can be used as AGC(Auto Gain Controller) to maintain
a constant recording volume. Besides, a dynamic wind reduction filter is built in on recording path. The
filter can detect the level of wind noise and on/off dynamically to keep the recording quality.
SounzRealTM digital sound effect technology is configurable to provide better listening experience.
OminiSound EXPTM expands the sound field of embedded stereo speaker. BassBack EXPTM and TruBass
EXPTM bring LFE(low frequency effect) to listeners without subwoofer needed. OmniHeadphone EXPTM
provides broader sound field when wearing headphone. TruTreble EXPTM adds processed harmonic tones
at high frequency, bringing more melody and details for music listening.
ALC5640 only requires two voltage supplies and consume ultra low power, making it ideal for mobile
devices.
