Giới thiệu Mạch giải mã AK4490EQ Chip EQ II2S DAC 32BIT 768K tại Lotte Market

Description:
AK4490 is AKB the fourth generation decoder chip, is the world's first to support 32BIT 768K decoder chip, technicallycomprehensive than AKM43XX series.
The chip is part of the left and right channels and analog reference voltage using an independent power supply, respectively, effectively reducing crosstalk.
Four kinds of digital filter mode AK4490 with adjustable, but also incorporates a newly developed analog circuits to achieve a rich bass sound field and the digital section with a separate 32-bit digital computing module provides a complete 32 bit processing.
AK4490 AKM useda newly developed switched-capacitor filter, greatly reducing the impact caused by noise shaping to achieve a very lowdistortion of music playback experience
Electrolytic capacitors adopt 4700UF 35V electrolytic
Full wave bridge rectifier circuit ensures strong support for a steady stream of power.
Resistance select ring copper foot metal resistance, the main circuit employs a precision ± 1% ring copper foot metal film resistors, it ensures the machine a good signal to noise ratio.
1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL ensures the good performance of the current.
AK4490EQ is the most high-end AKM decoder chip, support 32BIT 768K
