4 / 12 page –4– AD9022 REV. B EXPLANATION OF TEST LEVELS Test Level I – 100% production tested. II – 100% production tested at +25 °C, and sample tested at specified temperatures. AC testing done on sample basis. III – Sample tested only. IV – Parameter is guaranteed by design and characterization testing. V – Parameter is a typical value only. VI – All devices are 100% production tested at +25 °C. 100% production tested at temperature extremes for extended temperature devices; guaranteed by design and character- ization testing for industrial devices.
