Hello everybody,
I would want to know the LM3409's differential amplifier input CSN & CSP impedance. Unless I'm mistaken, it isn't mentionned in the datasheet.
Indeed, I would want to mesure the current flowing thought Rsns of a LM3409 by using an external current sense amplifier, and I'm afraid that the final impedance impedance (LM3409 + other amplifier) will be too low for such a low voltage accross Rsns.
Thanks a lot in advance,
Pascal
