I'm interested in building an adjustable electronic load as per Figure 6 of the apps note here: http://cds.linear.com/docs/en/application-note/an104f.pdf
Which ADI amplifiers would be the best match to replace the LT1210 and LT1006?
I build this active load :-)
The LT1006 kan be replaced whit any good precision opamp like the ADA4638-1.
Do NOT try to replace the LT1210!
You can have al look @ this website: http://www.circuitsonline.net/forum/view/105032/1/active+load
Klik on the links, and you wil see pictures i made of building this active load.
It needs verry short wiring!
Also the connection to your powersupply needs to be verry short if you do dynamic testing
of your powersupply.
I used a LM10 as a reference generator with a 10 turn pot and a dial to set the current level.
This active load is a beauty for testing powersupply's with fast signals.
Yust order some sampels for the LT1210 @ www.lineair.com
