reliability and result in failures not covered by warranty.
NOTES:
4.
JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. All voltages are with respect to GND.
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to “Functional Block Diagram” on page 3
and “typical application on Figure 2 on page 4 and Figure 3 on page 5. 9V < VDD < 20V, RTD = 10.0kΩ CT = 470pF, TA = -40°C to +105°C, Typical values
are at TA = +25°C.
