• AD587 output capacitance

    Is there a maximum output capacitance to ground that can be used with the AD587?  Is there any information as to how the output capacitance affects the output noise of the device?

    Hi Ben,

    6656 can take -55 to 125degC operating Temperature. So it might be that's what you see.

    We have AD587, LT1031 and LTZ1000.

    AD587 and LT1031 is comparable with LT6654 in terms of Specifications.

    LTZ1000 is better in terms of long term drift…

  • RE: Noise reduction for negative reference

    Thanks, Harry,

    I will take the BD680 for a start.

    For the AD587, does there exist a plot of noise voltage density vs frequency, including the flicker region?

    Especially the corner frequency would be very interesting.

    On the net I found an article…

  • Noise problem with a REF01 with booster transistor

    Hello all,

    I have a noise problem at an oscillator starting at abt 100 kHz up to abt 1 MHz offset from the carrier (see picture).

    I measured the spectrum of the power supply - and there is a remarkable noise increase around 500 kHz +/-.Problem located…

  • 4-20mA电流源

    ADI专家好!

        有一个项目的需求是:

        1. 产生4-20mA的电流源,精度0.1mA;

        2. 板卡只有15V电源输入和电流输出两个端口;

        3. 板卡的电源由远端的设备15V电源提供,板卡的电流输出在远端设备里通过一个小电阻接到15V电源对应的GND上,也就是说板卡这里没有地;

        我之前打算用AD586电压基准源和精密可调电阻实现,但发现电流最大只能到10mA,而且由于芯片本身的Ibias导致电流有一些偏差,AD587的Ibias好像更大,请问ADI公司的产品有没有可以实现类似功能的芯片或方案…
