• Amplifier similar to LTC6373

    I would ideally like to use the LTC6373 as the buffer amplifier to the ADAQ4003, but it is not available for at least 4 months.  Is there an amplifier that is similar? For reference, it needs to be very low noise, differential output, able to be supplied…

  • Dual LTC6373 (in series) driving AD4134 channel

    Hi experts,

    We are designing a data acquisition system with multiple wide-range analog inputs into several AD4134 ADCs (16 channels in all).

    We are considering the LTC6373 as front-end PGA and ADC driver but we need more than X16 gain as we need to cover…

  • LTC6373 slew rate and settling time information

    Dears,

          May I consult you experts about the slew rate and settling time other than Gain=16?

          In datasheet, we could only find the data specified at gain=16.

          How does it perform in other gains (eg. gain=0.25 and gain=0.5)?

          Would you mind provide…

  • RE: LTC6373 Output Amplifier Supply

    The LTC6373 is a fully differential output, which is why the two outputs will always be symmetrical around Vocm; therefore, it's not possible for one output to swing more than the other. 

    So if the more positive output goes into limitation because…

  • Stable gain with diferent frequency

    Dear all,
    I would like to use LTC6373 in our measurement system with frequency range from 10Hz to around 1MHz and I would like to ask three more komplex questions (at least for me to explain them).
    1: In datasheet is of LTC6373 stated that it is possible…

  • Considerations when designing a true bipolar fully differential output ADC Driver

     PDF

    This KWIK (Know-how With Integrated Knowledge) Circuit FAQ is a step-by-step guide that goes through the key considerations when designing a true bipolar fully differential output ADC Driver.

    The circuit highlighted in the note consists of a…
  • Some problems about instrumental amplifierLTC6373

    Hi, everyone:

    LTC6373 is a fullly differentially input and output instrumental amplifier. I want to use it to remove the common mode noise of the voltage supply. 

    For test, I give a sin wave voltage between Vin+ and Vin-(Vin- is connected to ground),…

  • RE: SNR of AD7768-1 with AD8250 at 48 kHz input frequency

    Wa$iM,

    thanks for indicating the LTC6373, a great device.
    But why didn't you add a gain of 0.2?
    This would allow using it directly with ADCs that have a 4.096V reference.

    Unfortunately, Precision Studio does not support SNR calculation for the LTC6373…

  • AD4007的ADC采集问题

    我用STM32H750驱动AD4007,其前端由LTC6373构成的全差分电路, 软件配置CPOL  =0,CPHA = 0,想读取AD4007的转换结果,但用逻辑分析仪采集数据,后面两个字节一直返回0x61,对此我很疑惑。    而如果通过0x14 写入寄存器0xF1,将会一直返回0X71。

  • RE: AD8422与数字电位器AD7376配合使用的输出信号失真

    我觉得你可以关注一下电位器电阻端的参数:

    以下是AD5293的参数,你可以看到端电容得大小,这个应该会影响你的带宽,同时还需要注意共模电流,这个共模电流可能会导致输出的失调误差。

    AD7376同样存在类似的问题

    所以,可能要慎重选择用数字电位器做可编程增益的仪表放大器的设计,尤其是考虑带宽的影响。

    我更建议选择ADA4254,ADA4255,LTC6373,ADA4558 这种内部做了可编程增益的仪表放大器,参数内部可控,这样会好很多。
