    How to calculate maximum usable value for pull-up resistor on op-amp (or in-amp) input?

    How can I calculate the maximum value an input pull-up (or pull-down) resistor can be, to detect a lead-off condition for ECG? A pull-up resistor is used to pull the input high if the electrode becomes disconnected from the patient. 10MOhms is often used...

    RE: Op amp with low peak-to-peak noise over 0.05-150Hz (searching for)

    Thanks for your suggestions. I will probably give OPA4316 a go, and the other two are good to know about; the shutdown feature of OPA4322S could come in useful. However, unfortunately none of them is as good as TLC2774 noise-wise (1.4uVpp + ~1.6Vpp for...
