Temperature Range (T_A)
-40°C to +85°C
CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
1. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379.
2. All voltages are relative to GND, unless otherwise specified.
3. 1V (min) on the BIAS pin required for FLT to be valid.
4. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside..
Electrical Specifications
V_DD = 2.5V to +3.3V, V_S = 1V,T_A = T_J = -40°C to +85°C, Unless Otherwise Specified. Parameters with MIN
and/or MAX limits are 100% tested at +25°C, unless otherwise specified.
Temperature limits established by characterization and are not production tested.
