NOTES
1
Temperature Range –40∞C to +85∞C.
2
Guaranteed by design and/or characterization data on production release.
3
Full-scale error applies to both positive and negative full scale.
4
Simultaneous 50 Hz and 60 Hz rejection is achieved using 19.79 Hz update rate. Normal mode rejection in this case is 60 dB min.
5
When the part is placed in power-down mode for a single conversion/second, at an update rate of 19.79 Hz, the current consumption is higher compared to when the
part is placed in standby mode as the crystal oscillator takes approximately 100 ms to begin clocking. The device will, therefore, use full current for the conversion
time and the 100 ms period required for the oscillator to begin clocking. However, if the conversion rate is lower, the current consumption will be reduced so that it
is worthwhile to use the power-down rather than the standby mode.
Specifications subject to change without notice.
