NOTES
1
Refers to the delay between receipt of a conversion command via the serial interface, and the actual start of the signal integration period.
2
In the intended modes of operation, as described in this data sheet and accompanying applications literature, these errors and drifts are reduced to negligible levels via
firmware techniques.
Specifications subject to change without notice.
