NOTES:
1. All voltages are referenced to ground.
2. Valid for design revisions D1 and above. The supply range for Rev. C2 and below is 4.5V < 5.5V.
3. Thermometer error reflects temperature accuracy as tested during calibration.
4. Logic 0 voltages are specified at a sink current of 4 mA
5. Logic 1 voltages are specified at a source current of 1 mA.
6. ISTBY, ICC specified with DQ, CLK/ CONV = VDD, and RST = GND.
7. Drift data is based on a 1000hr stress test at +125°C with VDD = 5.5V
8. Measured at VIH = 0.7 x VDD or VIL = 0.3 x VDD.
9. Measured at VOH = 2.4V or VOL = 0.4V.
10. Load capacitance = 50 pF.
11. tCWH must be 10 ms minimum following any write command that involves the E2 memory.
12. 250ns is the guaranteed minimum pulse width for a conversion to start; however, a smaller pulse
width may start a conversion.
Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product. No circuit patent licenses are implied.
Maxim reserves the right to change the circuitry and specifications without notice at any time. The parametric values (min and max limits) shown in the Electrical
Characteristics table are guaranteed. Other parametric values quoted in this data sheet are provided for guidance.
