  Good morning.  I have a customer inquiring as to how low the freqeuncy of a signal can be to drive the analog inputs of the AD9214-105 and the AD6644-65.  He needs to be able to accommodate some signals that will be in the range from 50KHz - 100KHz.


  Can either or both of these parts handle a signal frequency this low if using the AD8138 in a DC coupled circuit?


  Also, what is the life expectancy of each of these parts?  In other words, does ADI have an expected PDN date for each of these parts?  Thank you.
