LTC6268 input bias current vs. Temperature

Hi,

The graph provided for LTC6268 input bias current vs. temperature does not allow me to see values at temperatures below 50C. Is there a table I can get with the values shown in this graph? I need low bias current, but only up to 45 or 50C and the scale of the provided graph is inappropriate to discern values at these temperatures.

Thank you for your help,

Mike Henderson

    Hi Mike,

    The graph of input bias current vs temperature you're referring to is a Typical plot and not a guarantee. A safe bet would be to count on about 100fA of input bias current for temperature < 50 deg. C typically. Any more granularity beyond that would be hard to come by because the only guarantee is that over the entire temperature range, the input bias current would be less than 900fA (-40C to 85C) for the "I" version.
