• RFI FILTER AD8221 Y AMPLIFICATION STAGE ... TO THERMOCOUPLE

    Dear Community

    I plan use the ad8221 for amplify the signal of thermocouple to 0 - 5V. 0 - 50ºc (considering the addition of the cold joint (+ 25ºC)

    It is divided into two stages, the first stage is ad8221arm Gain = 100, and the second stage…

  • AD8221, Vin+=Vss Input

    Hi,

    I'm planning to use the AD8221 to measure current on the low-side of an AC Load. Before the current is measured, however, I plan to apply a 2.5V DC signal to the Neutral lead of the load to determine Neutral->Ground Isolation. When this occurs…

  • AD8221 Rg Parasitics Cause Oscillation

    Hello,

    I have 2 AD8221 layouts, one which works well, and one identical schematic, different layout which has oscillations on the output.

    I have probed the inputs and they look good. If I remove my two resistors and open switches between RG terminals…

  • AD8221 gain of <1

    I am evaluating a circuit that uses an AD8221. The circuit is from a product I have bought recently and I am trying to establish what it does so I can develop using an alternative approach.

    Circuit below:

    R6+R3 (or R4+R5) form a potential divider on the…
