• REF193: Output oscillation

    I am using the REF193 as a voltage supply of 3V/10mA, with an external 1uF and
    three 100 nf ceramic bypass capcitors. I am measuring some instabilty in
    frequency harmonics of 7Hz. What may be the reason.

     

    The REF193 should not can any…
  • 关于REF193基准电压带载能力的提问

    我按照REF19系列的规格书上搭建出了基本的电压基准电路,所用芯片为REF193芯片,空载时,Vout正常输出3V;但是当接入100R的负载时,输出电压降到了300多mV;接入470R电阻时,输出电压也只有1.4V左右,带负载能力很差,远没有3V输出电压,请问下这是正常现象吗?

  • Comment on REF193_REF193ES模型

    Ref193没有E级产品。我们仅提供REF193GS。该产品可能已经停产,我已抄送给Kim并请他确认。

  • REF193_REF193ES模型

    非常荣幸能与您联系。有一位客户想知道是否存在器件REF193ES及其数据手册。我在网站上找不到。请帮帮我。

  • RE: AD7091R-4 offset

    Hi Karen,

    Thank you for your reply.

    Our customer will use ADR5045 (5V) as reference in his application.

    As the result of his test on his preproduction board, offset error is about 5~6LSB.

    Datasheet says that offset errpr is +-1.5mV using internal…

  • AD8227 as tenso AC bridge amplifier - overshoot problem

    Dear Analog Devices,

    I have a question about AD8227 as amplifier used in AC-excited tenso bridge. I'm using AC square wave excited full bridge. Exciting signal comes from 3V switching by analog switch (signal is bipolar). Signal which control switching…
