NOTES
1VREF = 10.0 V, Conversion Rate = 100 kSPS unless otherwise noted. Values are post-calibration.
2Values shown apply to any temperature from TMIN to TMAX after calibration at that temperature at nominal supplies.
3Values shown are based upon calibration at +25°C with no additional calibration at temperature. Values shown are the typical variation from the value at +25 °C.
4See “APPLICATIONS” section for recommended voltage reference circuit, and Figure 11 for dynamic performance with other reference voltage values.
5See “APPLICATIONS” section for recommended input buffer circuit.
6Typical deviation of bipolar zero, –full scale or +full scale from min to max rating.
*For explanation of input characteristics, see “ANALOG INPUT” section.
Specifications subject to change without notice.
