NOTES
1
An external calibration trim can be used to zero the error @ +25°C.
2
Defined as the maximum deviation from a mathematically best fit line.
3
Parameter tested on all production units at +105°C only. C grade at –25°C also.
4
Maximum deviation between +25°C readings after a temperature cycle between –45°C and +125°C. Errors of this type are noncumulative.
5
Operation @ +125°C, error over time is noncumulative.
6
Although performance is not specified beyond the operating temperature range, temperature excursions within the package temperature range will not damage the device.
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.
