NOTES:
1) All voltages are referenced to ground.
2) See Figure 2 for TYPICAL OPERATING CURVES.
3) I
4) Drift data is based on a 1000hr stress test at +125°C with V
5) See Timing Diagrams in Figure 3. All timing is referenced to 0.7 x V
6) Load capacitance = 50pF.
7) t
8) 250ns is the guaranteed minimum pulse width for a conversion to start, however, a smaller pulse
