AK4495SEQ Dual Chip Decoder Board (Finished)
Product Description:
This product is all genuine original parts, plain, pure quality; the use of high quality original parts, not only the safety and quality to be protected, long life, more important is to make the actual performance to achieve a strong guarantee of design goals. The pursuit of first-class quality is our consistent purpose.
product details:
AK4495S is AKM fourth generation decoder chip, is also the world&39;s first support 32BIT 768K decoder chip, technically beyond the AKM43XX series. The chip simulates part of the left and right channels and the reference voltage is used independently of power supply, effectively reducing the crosstalk. The AK4495S has four digital filter modes that are also integrated with a newly developed analog circuitry to achieve a rich sound field and bass, and the digital part provides a complete 32 bit processing with a separate 32-bit digital arithmetic module. AK4495S AKM company developed the latest switching capacitor filter, greatly reducing the impact of noise shaping, to achieve a very low distortion of the music player experience. At the same time Audio 4 Pro (TM) series of chips with excellent sound performance, this is our important reason to choose this chip
using the original AK4495SEQ (2) NE5532
electrolytic capacitor signal main circuit using Philips, ELNA, Panasonic, and other brand name, the main filter capacitor using NOVER audio dedicated capacitance 4 4700UF, full-wave bridge rectifier circuit to ensure a strong stream of continuous power support.
resistance selection of five-ring metal resistance, the main circuit with 1% accuracy of the five-ring metal film resistors to ensure a good signal to noise ratio.
PCB with 1.6mm thick double-sided plate, 2.0 oz thick copper, tin spray the whole process to ensure the size of the current through the performance of good. First-class PCB quality.
power supply part of the current use of the most stable heat regulator chip LT1963EQ-3.3
PCM format up to 384K, support DSD64 and 128.
shipped to send NE5532 2, only when the test, the customer can choose a more high-end op amp
Supports analog balanced output
Power supply parameters:
1. Two groups of AC 9V (more than 10W per group)
2.1 group AC double 12V or double 15V (15W or more)
The above power supply needs to be connected at the same time
Motherboard size: 161 * 115MM
There are two situations when this product is used:
1. Empty/connected high: PCM mode.
2. Connect low: DSD mode.
