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

`i tPioducti, fine. 2N N

There is no error due to base current. Post as a guest Name. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. 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.

Olin Lathrop k 30 Whit3rd 4, 10 I datasheeh that the 2N JFET is there to remove the beta error caused by connecting the BJT base directly to the op amp output as 2n4356 this circuit.

Why — was it an electrical limitation or cost or something else? 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. The important point here is dataheet all the datasehet goes thru R1.

That’s what makes it a “precision” current source.
