Product Introduction:
AK4490 is a new generation Premium 32 bit digital analog converter (DAC), a newly developed integrated
switched capacitor filter "OSR Doubler", there are five types of 32-bit digital filter; can receive up
to 768kHz PCM data and 11.2MHz DSD data, ideal for high-resolution audio sources player, widely used in
the network audio, USB DAC and car audio systems.
Product Details:
All components of this product are original authentic, pure unpretentious, quality; the use of high-
quality original parts, not only quality and safety are guaranteed, long service life, more
importantly, that the actual performance can meet the design goal of a strong guarantee.
1.Using original AK4490EQ, op amp AD827, LT1963-3.3 2.Imported electrolytic capacitor 4700UF / 35V electrolytic NOVER brand, other capacitive imported from
Siemens or Philips Taiwan brand names, the use of full-wave bridge rectifier, ensure strong support for
a steady stream of power. 3.Resistance selection Rings feet of copper metal resistance, the main circuit employs a precision of
± 1% copper foot metal film resistors rings, ensure the machine a good signal to noise ratio. 4.using 1.6mm thick sheet double-sided PCB, 2.0 oz copper thickness, HASL whole process to ensure that
the size of the current through the good performance. PCB-class quality.
5.AK4490EQ is a new generation Premium 32 bits DAC, support 32BIT 768K
Package included: 1x Assembled AK4490EQ II2S DAC board support 32BIT 768K decoder
