How can I implement an RFI input filter and an DC return path together for the AD8221? The IA is used to amplify an very small signal (tens of uV) provided from a electromagnetic flowmeter. This voltage is generated from the ions in the liquid.Thanks
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.
R6+R3 (or R4+R5) form a potential divider on the…
It looks like the voltage you want at the output is not in the AD8221's output voltage range. The AD8221's specified output swing is -Vs +1.1V to +Vs-1.2V when operating at voltage spans of 10V or less. When the AD8221 is run from…
Thank you for considering Analog Devices for your circuit needs. For your question whether the AD8221 can directly drive the AD7693, the answer is yes. But you need to configure the two devices properly in order for the output of the AD8221…
Hi everyone, I'm choosing a low noise in-amp for an EEG project. I've found that AD8221 has the best noise characteristics for my set up.
Unfortunately it requires at least +-2.3V, I am running at 3.3V.
I've tested an AD620 which is very similar…
