However, you’d need to be careful about the gate capacitance causing stability problems.

I can sort of understand why TI wouldn’t bother updating an old app note, but I find it strange that LT wouldn’t update one of its “solutions” on its website.

Home Questions Tags Users Unanswered. Null 4, 10 22 Both of datassheet example circuits are old; the 2N transistor is a metal-case unit no longer easily available. Sign up using Email and Password.

If the opamp is powered so that its output can swing to 12 V or so, then just a single modern MOSFET would suffice, even for very large currents. Note that the LM is very old. Whit3rd 4, 10 That’s what makes it a “precision” current source.

The point of the FET and NPN transistors is to provide current gain so that the output current can be a lot more than the opamp output can provide. The old solutions still work!

I understand that the 2N JFET is there to remove the beta error caused by connecting the BJT base directly to the op amp output as in this circuit. Dwtasheet as a guest Name.

The important point here is that all the current goes thru R1. Email Required, but never shown.
