DAC 4.1x OK??

所有AN 解碼都用18BIT 精片,會不會OUTDATED??

All AN DACs use AD1865: Complete Dual 18-Bit 16 3 FS Audio DAC



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 MOS linear elements and laser-trimmed thin-film resistor elements, all fabricated on Analog Devices' ABCMOS process.

The DACs on the AD1865 chip employ a partially segmented architecture. The first four MSBs of each DAC are segmented into 15 elements. The 14 LSBs are produced using standard R-2R techniques. Segment and R-2R resistors are laser trimmed to provide extremely low total harmonic distortion. This architecture minimizes errors at major code transitions resulting in low output glitch and eliminating the need for an external deglitcher. When used in the current output mode, the AD1865 provides two ±1 mA output signals.

Each channel is equipped with a high performance output amplifier. These amplifiers achieve fast settling and high slew rate, producing ±3 V signals at load currents up to 8 mA. Each output amplifier is short-circuit protected and can withstand indefinite short circuits to ground.

The AD1865 was designed to balance two sets of opposing requirements, channel separation and DAC matching. High channel 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.

A versatile digital interface allows the AD1865 to be directly connected to standard digital filter chips. This interface employs five signals: Data Left (DL), Data Right (DR), Latch Left (LL), Latch Right (LR) and Clock (CLK). DL and DR are the serial input pins for the left and right DAC input registers. Input data bits are clocked into the input register on the rising edge of CLK. A low-going latch edge updates the respective DAC output. For systems using only a single latch signal, LL and LR may be connected together. For systems using only one DATA signal, DR and DL may be connected together.

The AD1865 operates with ±5 V power supplies. The digital supply, VL, can be separated from the analog supplies, VS and -VS, for reduced digital feedthrough. Separate analog and digital ground pins are also provided. The AD1865 typically dissipates only 225 mW, with a maximum power dissipation of 260 mW.

The AD1865 is packaged in both a 24-pin plastic DIP and a 28-pin SOIC package. Operation is guaranteed over the temperature range of -25°C to +70°C and over the voltage supply range of ±4.75 V to ±5.25 V.

幾多bit同sample rate都無問題架~最緊要好聽~今日有d dac依然係行緊16bit 44.1k無升頻~但出黎效果係滿意收貨~
所以唔使介懷數字規格~你收貨就ok

最緊要係聽聲收貨喎… x N


我仲用緊16bit 44.1k無升頻,如果24/192一定好,咁步步高咪好堅????

CAS = 方便,唔一定等同 hi-refs, 所以一樣可以拿部16bit DAC 玩CAS。而且少人知係這樣重易玩得好聲。

AN 既 cd player 同dac !
去音響展聽過!
又聽過朋友既!
係有動態,有音色,有音樂感既牌子!
佢好聲係因為佢既火牛,電容,銀線!
唔係咩高科技數據!
一句講唒!
AN 識調教乜野叫做好聲!

曾經托過一台試,可以咁講,如聽CD秒殺巿面上90%啲新一代DAC. 無論音塲動態厚度音樂感都好正,聽啲垃圾CD都有美化作用,連聽Internet radio MP3 都幾好,唯一美中不足係速度慢咗少少,同埋真係太大舊唔夠靚仔!

Index.

其實,現在的訊息含量根本好低。比24bit根本冇24bit.只是tune下。尤其中,中高,令人覺得有線條。

足16bit都偷笑。
