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, the “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 = 10kΩ, 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.
