- Figure 1. Weirdly, the "CATHODE" serves as the sense pin for active current source regulation
- Figure 2. The booster transistor Q1 can handle current beyond 4041 max IS and dissipation limits
- Figure 3. Schematic showing the DAC control of IS. IS = D amps, where D = PWM duty factor. The asterisked resistors should be 1% or better
- Figure 4. Additional zero and span pots to implement a single-pass calibration for best accuracy
