- OUT: Solder pad
- Load with 10nF cap (CM07FD103JO3) to ground
- Drags out tail-end of pulse
- Testing done with 1[MOhm] load of scope to COMP Port
- 1N5624 [Digikey] in parallel with resistor to minimize negative voltage seen relative to COMP Port
- Note: Offset COMP +1VDC to have the diode clamp around 0V, but if COMP Port is ground, will clamp adequately to protect ASIC load
- Load with 10nF cap (CM07FD103JO3) to ground
Operation
Expand title Info... If J2 = +10VDC (effects Tp1 & OUT) ← what scales output

Q1
[V] U1.7 TP1 OUT* Note(s) 0 ON -15 ~0 -5 ← Using fast turn on time to generate pulse +3.3 OFF +15 -90 +85 ← _TRIGGER: Normally in this state (otherwise won't work) *assumes load resistance to be negligible as it is a cap divider
