Description
Product Description
AKM's AK4490 is a new generation of premium 32-bit digital-to-analog converters (DACs). It integrates the newly developed switched capacitor filter "OSR Doubler". There are five types of 32-bit digital filters; it can receive PCM data up to 768kHz and 11.2MHz DSD data, very suitable for high-resolution audio source players, widely used in network audio, USB DAC and car audio systems.
Feature
1, using original AK4490EQ, operational amplifier AD827 2, electrolytic capacitors use 2200UF capacitors, other capacitors use imported Philips Siemens or Taiwan famous brand, using full-wave bridge rectifier circuit to ensure a strong continuous power support. 3. The resistor is a five-ring copper-foot metal resistor. The main circuit uses a five-ring copper-foot metal film resistor with an accuracy of ± 1% to ensure a good signal-to-noise ratio. 4.The PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. Best-in-class PCB quality. 5, AK4490EQ is AKM's next-generation Premium 32-bit DAC, supporting 32BIT 768K
