See Figure 4 for power dissipation at other conditions. 6Measured as the ratio of the change in offset voltage for 5% change in +V D. Specifications subject to change without notice. AD9049 REV. A –3– EXPLANATION OF TEST LEVELS Test Level I – 100% Production Tested. IV – Parameter is guaranteed by design and characteriza- tion testing. V – Parameter is a typical value only.
