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. I
7. Drift data is based on a 1000hr stress test at +125°C with V
8. Measured at V
9. Measured at V
10. Load capacitance = 50 pF.
11. t
12. 250ns is the guaranteed minimum pulse width for a conversion to start; however, a smaller pulse
width may start a conversion.
