• RE: ADA4805-1输出电压

    3.3V的电源可以正常输出 3.0V的基准电压源, ADA4805-1采用的是什么电源,如果也是3.3V电源,那么其输入共模电压将只能达到2.3V,无法接受3V输入电压

  • RE: AD7980基准电压使用OPA170作为电压缓冲器ADC数据不成线性

    1. 用示波器看看OPA170输出是不是震荡了 ?

    2. 推荐用ADI验证过的ADA4805, AD8031等做参考源驱动。

  • ADA4805 output voltage swing

    I am testing  current capability of op-amps by evaluating voltage swing to rails with simulation in PSpice.

    I do it by sweeping through a current source at the output (at 75°). For negative rail (and currents) the V2 is set to 0V.

    However ,ADA4805 shows…

  • RE: ADA4805-1能否满足,在电压电压为0~3V下,将200kHz的正弦波转换为方波

    ADA4805-1 的带宽范围为105MHz, 也可以满足双极性要求

  • RE: Op-amp as integrator

    Hello Jino

    Thank you for the recommendation. The ADA4805 seems to work in the application where we convert a CMOS 3.3V signal to a signal that swings between 0 and -6V with a rise and fall time between 1 and 2 microseconds. If the ADA4805 output has…

  • RE: ADC AD7176-2 driver IC use?

    Hi Sapana,

    Yes, I believe that the ADA4805 ICs are used as high resolution, high precision analog-to-digital converter (ADC) drivers.



  • RE: Alternatives to AD8244

    Hi Jake,

    Thank you for using ADI parts. As for your queries:

    1. Replacement for AD8244 - you can use ADA4805-1 (0.2 µV/°C Offset Drift, 105 MHz Low Power,Low Noise, Rail-to-Rail Amplifier).

  • RE: EVAL-AD7982SDZ : sampling rate and updating the display data

    Hell Karen,

    Thnak you for your support.

    > How important is it for you too use start streaming?

    Now I building demonstration environment of ADA4805-1 and precision ADC for our customer.

    So I need to run ADC continuously.

    If I can not run AD7982…

  • RE: AD7663


    In a fully differential ADC driver. the VOCM pin should be connected to your Vref/2. Please see attached example schematic using the ADA4940-1 a newer part which I also recommend  that can drive the AD7663. and then you can also use two single ended A…

  • RE: ADA4817 oscillation problem



      I don't like to use the word "never", but I'm tempted to say you will never get your circuit working.

    If you have nanohenries of inductance in your supply leads and 2-5pF of stray capacitance everywhere,

    and 1k-10k resistors…
