ELECTRICAL CHARACTERISTICS (continued)
(VCC = +12V, SEL1 = VCC, SEL2 = DGND, RRT = 124kΩ, NDRV1 = NDRV2 = open, TA = TJ = -40°C to +125°C, unless otherwise
noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: The MAX5077 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 MAX5077 oscillator frequency: fOSC = 1012 / (32 x RRT).
Note 3: The accuracy of the oscillator’s frequency is lower at frequencies greater than 1MHz.
