Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS

Note 1: The MAX5075 is 100% tested at TA = TJ = +125°C. All limits over temperature are guaranteed by design.
Note 2: Use the following formula to calculate the MAX5075 oscillator frequency: fOSC = 1012/(32 x RRT).
Note 3: The accuracy of the oscillator’s frequency is lower at frequencies greater than 1MHz.
