Discrete OP1-BP – a truly transparent, discrete operational amplifier module.
A NEW I/V CONVERSION AND OUTPUT STAGE FOR WEISS FLAGSHIP MEDEA+ DIGITAL TO ANALOGUE CONVERTER
Superb noise performance:

• 1nV/√Hz voltage noise density (1kHz)
• 30nVpp voltage noise (0.1-10Hz)
• 0.7pA/√Hz current noise density (1kHz)
• 80pApp current noise (0.1-10Hz)
• no common-mode current noise from bias cancellation

Outstanding distortion specifications:

• THD+N -152dB (+20dBu, 1kHz, 22kHz BW, 600Ω)
• THD+N -148dB (+20dBu, 10kHz, 80kHz BW, 600Ω)
• distortion spectrum consists almost entirely of 2nd and 3rd harmonic
• no significant crossover distortion, even with 200Ω load
• no significant common mode distortion, even with very high source impedances

Impressive AC performance:

• 50V/µs slew rte, highly symmetrical
• 95MHz gain bandwidth product
• 700kHz power bandwidth (20Vpp into 600Ω)
• 300kHz power bandwidth (20Vpp into 200Ω)

Superior DC precision:

• offset 10µV
• input bias current +-60nA
• input offset current +-10nA

Excellent load driving capability:

• 27Vpp(+21.8dBu) in 200Ω (+-15V supply)
• 20Vpp(+19.2dBu) in 100Ω (+-15V supply)
• 10Vpp(+13.2dBu) in 50Ω (+-15V supply)
• adjustable class A output current, factory trimmed to 30mA
• very low output impedance
• extensive short-circuit protection

Salient insensitivity to power supply deficiencies:

• very high PSRR with little degradtion towards high frequencies
• individual RC decoupling of amplifier sub-circuits eliminates the interaction of the various amplifier stages and makes the amplifier insensitive to power supply inductance
• high performance on-board decoupling capacitors, 2.4µF total
• no need for additional external decoupling capacitors
• recommended power supply range from +-5V to +-18V

Carefully thermal design:

• excellent stability of any bias condition
• full thermal isolation of the sensitive input stage from the power output stage
• fast settling of bias conditions after start up

Dimensions:

• 42 x 28 x 17mm (1.65 x 1.1 x 0.67 inches)
• API2520 standard pinout[localimg=400,268]1[/localimg]

这个是啥？

lkpkp

MEDEA+的全新模拟输出部分，源于MAYA

t1174

是出產給上一代升級?

schpeltor

嗯，看到maya就知道是和自己无关的东西了……

rayman

看不懂，只对听感感兴趣

是全新一代MEDEA+的模拟输出
上一代MEDEA可以升级

这样的模块独立做一台前级，那也是10w+的级别了。

MEDEA+现在接受预定

wl336

数据真恐怖。。。

t1174

其實也是 op-amp, 不知可不可能當一般 op-amp 用?

dragon

MEDEA+的价位多少？现在竞争对手很多哦
