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:
4. All voltages are with respect to GND.
5. _JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
6. For _JC, the “case temp” location is taken at the package top center.
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to Figure 1 on page 5, Figure 2 on page 6
and Figure 3 on page 7. 9V < VDD < 16V, RTD = 10.0kΩ, CT = 470pF, T_A = -40°C to +105°C, Typical values are at T_A = +25°C. Boldface limits apply across
the operating temperature range, -40°C to +105°C
