Specifications subject to change without notice.
Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min
and max specifications are guaranteed, although only those shown in boldface are tested on all production units.
Relative accuracy is defined as the deviation of the code transition points from the ideal transfer point on a straight line from the zero to the full scale of the device.
Full-scale calibration is guaranteed trimmable to zero with an external 50
Defined as the resolution for which no missing codes will occur.
Change from +25 C value from +25 C to T
The data output lines have active pull-ups to source 0.5 mA. The DATA READY line is open collector with a nominal 6 k
1 LSB, or 9.990 volts.
