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?
Does anyone know if there is any Evaluation Board that has AD8541 + AD1972 on board?
In operation, the input voltage does not exceed the supply voltage. But I want to protect the sensors interface circuit from malfunction.

There is nothing "wrong" with the AD8541 family. We split op amps into a precision group,
(less than 1 mV Vos, and less than 50 MHz) and a high speed group. (greater than 50 MHz).
The AD8541 family has some historical reasons why…
AD8541 is stable with supplies between 3V and 5V. Just take note that the Avo is not scaled up to the rails because there is always a headroom from the supplies of at least 500mV.
Hope this helps. Happy New Year!
AAnand928 said:My understanding was input offset voltage was too low like 0.1mV
Where did you get this value from? In datasheet of AD8541/8542/8544 says that offset voltage equal 1mV typically
