• AD8420: When there going to be LT Spice model?, I need it for CMR assessment.

    It has AD8420.cir but not sure how to install this into LTSpice.

    When you going to release LTSpice version of AD8420.

    Thanks.

  • What evaluation board could be used for AD8420?

    I'm looking for a medical EMG sensor application and found that AD8420 would suite.

    What evaluation board could be used for AD8420?

    What could be alternatives?

    I need to meet low power, low noise, nano Amp Bias, high CMRR, gain > 1000 requirements…

  • RE: AD8420 ECG application

    5. Because of the way this circuit is set up, the gain is within the servo loop, which changes the cutoff frequency. Normally you would expect 1/(2*pi*R*C) to be the cutoff frequency, but in the circuit shown, the cutoff is 101/(2*pi*R*C), which is…

  • Help needed with AD8420 design

    Hello everyone, I have a problem with the AD8420 in-amp in a new electromagnetic flow meter design. Please refer to the attached image of a section of the circuit diagram.

    The AD8420 is powered from a 3 V supply with the REF pin connected to mid-rail…

  • RE: High Voltage Input Instrumentation Amplier

    Hi Terry,

    In response to your inquiry about the AD8420, it has not released yet, but if your design schedule allows it I believe it would also be a very good choice for your design. It has high input-protection, allows for single-supply operation, and…

  • RE: Whats the best Inamp for high speed current sensing?

    Hello Ian,

    Yes, I agree that your choice would be sufficient enough in your application. But you may also want to consider AD8420 or AD8421. AD8420 is a wide supply range, micropower, rail to rail inAmp but the bandwidth is a little lower. AD8420's CMRR…

  • RE: AD8237 Spice Model doesn't work with OrCAD

    Hi,

    For the meantime, you could try using AD8420 which is almost similar to AD8237. Both are micropower instrumentation amplifiers used for ECG applications.

  • RE: AD8421使用疑问

    你的供电是12V,推荐AD8420。如果是5V供电的话,推荐AD8237.

  • RE: 单电源3.3V供电 仪器仪表参考端处理

    您好。请您参考AD8420和AD8237是否满足您的设计要求。

  • Problem with the ad8420 configured as a transmitter to get 4-20mA at its output

    Hi. I have a problem with a design that I made with the AD8420. I proceed to place the schematic diagram to explain more clearly my problem.

    Design a transmitter that receives a voltage of 0 to 10V at its input. The output must obtain a current in the…
