NOTES:

7. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization

and are not production tested.

8. Limits established by characterization and are not production tested.

Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to the Block Diagram on page 4 and

Typical Application schematics starting on page 5. VDD = 17V, RRAMP = 54k, CRAMP = 470pF, TA = -40°C to +125°C, Typical values are at TA = +25°C.

Boldface limits apply over the operating temperature range, -40°C to +125°C. (Continued)
