May you please provide any data of AD8541/AD8542/AD8544's voltage noise in low frequency? I mean 0.1-10 Hz uV p-p.
I want to use it for EEG/ECG amplifier: exactly AD8542 - one op-amp for getting reference voltage (Vmid)- for a voltage follower in resistor divider and second op-amp for Driven Right Leg circuit where I need good stability (high phase margin, unity stability, no phase reversal).
In datasheet there is only the information that this op-amp is proper for medical equipment, but no information about the LF noise...
So information about 0.1-10 Hz voltage noise is not available for AD8541?
If AD8541 is not good for RLD, which op-amp (cheap, low power, 3.3V) is proper for RLD?
I was thinking about AD8539, but AD8607 also looks good. I will take this op-amp for RLD circuit.
Thank you Harry!
