Notes:
2. In both Triangular and Hershey-kiss profiles, modulation rate is
employed with a frequency of ~31.25 kHz. In random profile,
modulation rate is ~ 8.6 kHz.
3. The random profile supports up to ±1.030% center spread or -
2.10% down spread (ordering codes A through H).

mode, a pull-up resistor of 10 kΩ or less is recommended if pin 1 is not externally driven. If pin 1 needs to be left floating, use the NC option.
5. A capacitor of value 0.1 µF or higher between Vdd and GND is required.
Table 5. Absolute Maximum Limits
Attempted operation outside the absolute maximum ratings may cause permanent damage to the part. Actual performance of
the IC is only guaranteed within the operational specifications, not at absolute maximum ratings.
