The AD1865 is a complete, dual 18-bit DAC offering excellent THD+N and SNR while requiring no external components. Two complete signal channels are included. This results in cophased voltage or current output signals and eliminates the need for output demultiplexing circuitry. The monolithic AD1865 chip includes CMOS logic elements, bipolar and ...

quirements, channel separation and DAC matching. High chan-nel separation is the result of careful layout. At the same time, both channels of the AD1865 have been designed to ensure matched gain and linearity as well as tracking over time and temperature. This assures optimum performance when used in stereo and multi-DAC per channel applications.

ad1865是一款完整的双通道18位dac，具有出色的总谐波失真加噪声(thd+n)和信噪比(snr)性能，且无需外部元件。它包括2个完整的信号通道，能够产生同相电压或电流输出信号，且无需输出解复用电路。单芯片内置cmos逻辑单元、双极性和mos线性单元以及经过激光调整的薄膜电阻单元，所有单元均采用adi ...

After some test with No oversampling DAC chip I think that the AD1865 is the best. If compared to the new technology DAC chips like AD1955 and CS4397 since to be more natural. The old TDA have a too close sound and with these some particulars are lost. The preview of my article is …

2014年11月26日 · DAC-END 24 (AD1865 NOS DAC ) AD1865 is a dac chips with natural sound and inspiring. ago, Andrea and I had success with DAC-end, now I have upgraded dac-end 16-bit, 24-bit up-end DAC. it receives the input frequency of 192 KhZ- 24bit and special use Amanero to use USB audio source from your computer. invited to view some links:

DAC End 2 by Andrea Ciuffoli - starting in the 2010 INTRODUCTION. After the good result obtain with the DAC End I have design with Nguyen Quang Hao a set of boards to create a cheaper project with a sonic performances very near. The No Oversampling DAC give a more natural sound but if you ear the TDA1541 and TDA1543 seem to lose details.

For supplying I used for low-noise voltage regulators. Two LP2992-5V for feeding of analog and digital part of DAC, one LT1964-5V for negative analog supply of DAC and one LP2992-3V3 for supplying of input module. AD1865 works with 5V TTL logic but it also accept LVTTL same like 74HCT164 that circuit works with 3.3V logic on the I2S input.

The No Oversampling DAC give a more natural sound but if you ear the TDA1541 and TDA1543 seem to lose details. The AD1865N-K with passive I/V give a perfect combination, natural sound and all the details. So this project is the end of my DAC projects also if someone speak very well about the AD1862. The AD1865N-K give the better performances ...
