MicroCC microamp-range constant current source

Thursday, March 29th, 2012

MicroCC is a constant current source, but focused on the low current microamp range. It uses the Touchstone Semiconductor TSM6025 voltage reference, a drop in replacement for the MAX3025 with better than 15PPM stability. The TSM6025 used both as the reference voltage and regulator for a TS1001 op-amp (previously covered here) powered by a...
