    Hi all,

    I am working on a conductivity cell with K=5. I want a current pulse generator circuit for exciting the cell and i need current <=1mA. Also it should be possible to control these pulses using a micro controller's io pin. Can any one help me to design such a circuit?

    Many thanks

    What sort of pulse do you require? What rise time / fall time, repetition rate and width?
