• Alternatives to AD8244

    I'm looking for a unity-gain, low-power op-amp to replace an AD8244 as a voltage follower.  I only need one amplifier circuit (not the four that the AD8244 has) and care about low cost, low current draw, ability to run on a single-ended 3.3 V supply…

  • Is AD8244 What I want

    I am doing some active filtering and I am looking for what will work best for my application.  I had someone recommend the AD8244.  When I go to the filter wizard it doesn't even give the option for the AD8244.  

    The project is I have to put a high pass…

  • AD8244 Oscillating with buffered High Pass RC Filter

    Hey, I am having trouble with using the AD8244 for buffering a RC high pass filter. As I saw the datasheet describes creating a sallen-keys filter I figured this chip would be a great option - particularly as I need to do this for 32 channels, the reduced…

  • Is it possible to bypass AD8244 input capacitance (4pF is rather high)

    I plan to use AD8244 as a input in an EEG amplifier. Using AD8244 I can achieve extremally high DC-impedance (resistance), but the capacity is still 4pF. 4pF paralelly with 10TOhm for 10Hz (alpha band in EEG) degrades DC-impedance a lot.

    Is it any possibility…

  • RE: Hello! Is it possible to use the buffer AD8244 as a RLD?

    Yes, RLD = Right Leg Driver.

    I want to use AD8244 as input buffer and Low-Pass Filter for EEG device. But I'm not sure, can I use AD8244 as RLD?

  • Amplifiers for EEG measurement

    Hello,

    I'm trying to find solution for EEG measurement (1-channel). 

    According to EEG application note, below components are recommended. 

     - AD8220(AMP), AD8244(Buffer), AD8422(AMP), AD7768-1(ADC).

    1. Can I use AD8244 without AD8220 to connect electrode…
