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. θ 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. For θ JC , t he “case temp” location is taken at the package top center.
6. 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” schematics on page 4 and 5. V DD = 15V (Note 10), R t = 10k ? , C t = 3.3nF, T A = -40 to +105°C, Typical values are at T A = +25°C.
Boldface limits apply over the operating temperature range, -40°C to +105°C.
