Other Parts Discussed in Thread: TL431LI, LM334
I work on a current sensitive circuit and I'd like use the current limiting feature of REF6250. It's stated as +/- 3mA. On page 22 of D/S, two equations given without any units:
Isc=80e-9*Rss+3e-3 - eqn 4
IL=23.75e-9*Rss+0.15e-3 - eqn 8
I understand IL is the recommended current the device will operate safely, and Isc is the current level the device will "hard-limit" the output to. I presume the hard limit can't be changed.
Will you please clarify the units in the equations? The aim is to operate the device at 2mA. What it the correct value of Rss?
I intend to use this REF as the current source of an NPN, not as an ADC reference.
