NOTES:
1) All voltages are referenced to ground.
2) See Figure 2 for TYPICAL OPERATING CURVES.
3) ISTBY, IDD specified with DQ, CLK/CNV = VDD and RST = GND.
4) Drift data is based on a 1000hr stress test at +125°C with VDD = 5.5V.
5) See Timing Diagrams in Figure 3. All timing is referenced to 0.7 x VDD and 0.3 x VDD.
6) Load capacitance = 50pF.
7) tRI must be 10ms minimum following any write command that involves the E
2 memory.
8) 250ns is the guaranteed minimum pulse width for a conversion to start, however, a smaller pulse
width may start a conversion.
