Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 5. θJA 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 θJC, the “case temp” location is the center of the exposed metal pad on the package underside. 7. For θJC, the “case temp” location is taken at the package top center. 8. All voltages are with respect to GND. Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to “Functional Block Diagram” and “Typical Application” schematic on pages 3 and 4. VDD = 15V (Note 12), Rt = 10kΩ, Ct = 3.3nF, TA = -40°C to +105°C (Industrial) or TA = 0°C to +70°C (Commercial), Typical values are at TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +105°C or 0°C to +70°C .
