• ADA4805-1输出电压

    我用ADA4805-1作为ADR4530的跟随器,供为单3.3V,但是两块电路板一块的输出是2.8V,一块是3.2V,非常奇怪。我将其供电引脚跳线到3.6V供电后正常使用,请问这是什么原因呢?(输出负载已经断开,所有电压的测量工具都是安捷伦34465A)

  • ADA4805-1 Internal capacitance component

    Hi,

    I would like to use ADA4805-1.

    So, I have a question. Please help me.

    Question:

    I am considering ADA4805-1.

    The application is motor current detection.
    I use it as an I-V amplifier to detect the voltage difference from the sense resistor…

  • 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

    我们的工作电压0~3V,能否推荐几款低功耗(电流小于0.4mA),采用双电压供电方式,低失真,低噪声的电压比较器,能将200kHz的正弦波转换为方波?

    查阅相关资料,可以确定需要将ADA4805-1的供电电压提高至5V

  • ADA4805-2ACPZ-R7 to drive differential ADC

    Hi Friends,
    I'm designing an ADC for my input signal +/-4VPP.
    But the amplifier ADA4805-2ACPZ-R7 is a single-ended opamp.

    How to drive a fully differential ADC from a single-ended bipolar signal.

    Also, can I use +2.5V as a reference voltage for a +/…

  • ADA4805 output impedance

    Hello, 

    From the datasheet, how can I get ADA4805 output impedance @100kHz ? 

    Thank you for your help on this. 

    Best regards, 

    Benoît, 

  • ADA4805 Follower with Floating Input

    If I connect the ADA4805 as a unity gain follower and leave the (+) input floating, where will the output go?  I'm using a +/-3V split supply.  I assume it will saturate at one of the power rails.  Can you tell me which one?

  • 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…

  • [hurry]LTC6811-1 & LTC6811-1's VREG is not work.

    Hi.

    (Please refer to the circuit diagram)

    BMS was configured using LTC6811-1. 20cells were connected using two ICs.(LTC6811-1 & LTC6811-1)

    When the BMS board is power-on, no SPI-data communication.

    I checked, the resistance level was low like a short…
