• RE: Is there an Op Amp that can clamp the output at  5V (unipolar operation)?

    Hi Ted,

     

    According to one of our colleagues, AD8036 and AD8037 are the only clamping amplifiers that Analog Devices have.

    AD8036 operates at +1 gain while AD8037 operates at +2 gain.

    AD8036 is guaranteed to operate on maximum of +/-6V of supply voltage…

  • RE: Looking for OPA with voltage limiting function

    I also have to consider the OPA698.

    Regarding the AD8036, I started playing with the Spice model (using LTSpice) and I am a bit surprised.

    I simulated a non-inverting amplifier with a gain of 1, just like circuit TPC 4 of the datasheet, with +Vs=5V…

  • RE: ADC drive amplifier with over voltage limit/clamp feature

    Hi Joe,

    I have confirmed that my customer is designing the circuit by using AD8036 which you recommended.

    Thank you very much for your valuable recommendation.

    Best Regards,

    Ricky

  • RE: Limiting Amplifier - Voltage Clamp

    Thank you Emman for your answer. I have ordered a couple of AD8036 for testing purpose.

  • RE: clipping (limiter) circuit for ADC frontend

    Hi Julian,

    ADI offers clamp amps that could suit your needs like AD8036/AD8037low distortion voltage feedback clamp amplifier. I'm not sure what exactly is your operating BW but this clamp amps has small signal BW of 270 MHz. Here are some good stuff…

  • ADA4528 for thermocouple amplification

    Hello,

    in the Application Note AN-1114, I saw an instrumentation amplifier built with ADA4528. I'm very interested about this circuit (especially about the auto-zero capability). My problem is that it can output a negative voltage, and I don't want…

  • [ADI微博问答精选]多级放大的放大器该如何选择

    ADI微博网友@小究同学: 选前置放大器的时候,看到有一部分放大器是ADA打头的,似乎都比较新一点,是不是这样子的呢@ADI亚德诺半导体

     

    ADI专家回答:大致来讲是这样的。如果要用到ADI 的运放芯片,请与我们联系,帮您推荐合适型号。

     

    ADI微博网友@小究同学:目前的要求是这样,当作超声波探头的前置放大器使用,输入信号为微伏级、双极性信号,单端输入,希望放大器的输入阻抗要大,带宽大于20MHz,计划采用多级放大至1Vp-p左右,经过滤波后,通过AD8036输出箝位,再通过AD8138
