NOTES:

1) All voltages are referenced to ground.

2) See Figure 2 for TYPICAL OPERATING CURVES.

3) I_STBY, I_DDspecified with DQ, CLK/CNV = V_DDand RST = GND.

4) Drift data is based on a 1000hr stress test at +125°C with V_DD= 5.5V.

5) See Timing Diagrams in Figure 3. All timing is referenced to 0.7 x V_DDand 0.3 x V_DD.

6) Load capacitance = 50pF.

7) t_RImust be 10ms minimum following any write command that involves the E²memory.

8) 250ns is the guaranteed minimum pulse width for a conversion to start, however, a smaller pulse

width may start a conversion.
