Functional operability under any of these conditions is not necessarily implied. Exposure to absolute maximum rating conditions for extended periods of time may affect device reliability. 2+V REF ≥ –V REF under all circumstances. 3Maximum junction temperature (t J max) should not exceed +175 °C for ceramic packages, and +150 °C for plastic packages: tJ = PD ( θ JA) + tA PD ( θ JC) + t C where PD = power dissipation θ JA = thermal impedance from junction to ambient ( °C/W) θ JC = thermal impedance from junction to case ( °C/W) tA = ambient temperature ( °C) tC = case temperature ( °C) Typical thermal impedances are: Ceramic DIP θ JA = 56 °C/W; θ JC = 20 °C/W Ceramic LCC θ JA = 69 °C/W; θ JC = 23 °C/W PLCC θ JA = 60 °C/W; θ JC = 19 °C/W.

Test Level II – 100% production tested at +25 °C, and sample tested at specified temperatures. Test Level III – Sample tested only. Test Level IV – Parameter is guaranteed by design and characterization testing. Test Level V – Parameter is a typical value only. Test Level VI – All devices are 100% production tested at +25 °C. 100% production tested at tempera- ture extremes for extended temperature devices; sample tested at temperature ex- tremes for commercial/industrial devices.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD9002 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. WARNING! ESD SENSITIVE DEVICE |
