• RE: AD820 circuit

    Hi Adam,

    Thank you for sending this inquiry.

    R4 is the NTC resistor, which is essentially a thermistor with a negative coefficient, i.e. resistance decreases as temperature increases. When R4 is set to 50k (the maximum value of the NTC resistor), 2.5V…

  • OP184: Replacement with the AD820 and NULL Pin

    Is it possible to replace the op AD820  with the op OP184? What means the pin
    connection NULL?

     

    The OP184 and AD820 share a similar pin out but they vary significantly in
    their bandwidth, offset, and noise. I would not consider them to be drop…

  • RE: Can AD820 "NC" be grounded?

    Hi,

    The NC pin has no internal connection and you can connect it to ground.

    Thanks and regards!

  • RE: High Pass Filters for AD620 and AD820

    The following paper creates a high pass filter by putting a capacitor and resistor in the place of the gain resistor on a AD620.  EMG signals contain large offsets that must be filtered by a high pass filter.  I found no mention of using this technique…

  • AD820 Junction temperature

    Hello

    Could you  teach me about the junction temperature of AD820 because AD820 datasheet does not describe the junction ?

    I think that the junction temperature is 150 degree celcius  as other parts and is it correct ?

    Datasheet describes the internal…

  • AD820 spice model

    Hello

    I think that AD820 spice model does not include temperature charachtristcs.

    Is it correct ?

    Our customer  uses AD820 spice simulation (using LTspice)

     but the  current consumption in simulation result is 2ma@ 25 degree celcius and  ~9mA @ 85 degree…

  • AD620 and AD820, underwater 60Hz noise ("clicking" or clipping)

    I have two differential amplifier boards that each use AD620 and AD820 op amps.  I'm using the boards for electrophysiology recordings from lobsters.  The boards are in a waterproof case and attached to the lobster's back to allow the animal to move…
