Other Parts Discussed in Thread: VFC320

Hi, I'm interested to purchase this product but I have the following questions about it.


1)What's the input range of current and can it be as low as 1 nA?

2)Can we set a threshold voltage so after that it fires the pulse?

3)Can we set leakage current for this product?

4) Can we use this product as Integrating and Fire?

    Hi Macan,


    1)What's the input range of current and can it be as low as 1 nA? No, the VFC320 minimum input current is specified as 250 nA, and it is optimized for 250 uA input current.

    2)Can we set a threshold voltage so after that it fires the pulse? I do not know of any way to do that with the VFC320.

    3)Can we set leakage current for this product? I assume this is in reference to the open-collector output leakage current? The leakage current cannot be set, but it is specified for a 1 uA maximum at TA of 25 C.

    4) Can we use this product as Integrating and Fire? The VFC320 is intended for either V/F, or F/V operation. The integrator appears that it could be used stand alone, but the rest of the circuitry is designed specifically for the intended functions.
