2N3456 – N-CHANNEL SILICON JUNCTION FIELD-EFFECT

Sign up using Facebook. 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 that all the current goes thru R1. 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.

In fact, in this case datashete opamp output current is ideally 0. Probably updating solutions is not a business priority.

The point of the FET and NPN transistors is to provide 2n34556 gain so that the output current can be a lot more than the opamp output can catasheet. There is no error due to base current. The size of the silicon slab used was very limited.
