Using REF200 as 100uA precision reference

Kerry D. Wong has posted an article:  Using REF200 as 100uA precision reference The simplest way to use REF200 is to utilize either of its two independent current sources. In this case we obtain a 100 µA reference current. Because REF200 has a built-in current mirror, you can obtain currents of 50µA, 100µA, 200µA, 300µA […]
