Electrical Characteristics
V
Note 1: For operation in ambient temperatures above 25°C, the device must be derated based on a 150°C maximum junction temperature and a thermal resistance
of 101°C/W junction to ambient for LM2907-8 and LM2917-8, and 79°C/W junction to ambient for LM2907-14 and LM2917-14.
Note 2: Hysteresis is the sum +V
Note 3: V
the two factors that cause the tachometer gain constant to vary from 1.0.
Note 4: Be sure when choosing the time constant R1 × C1 that R1 is such that the maximum anticipated output voltage at pin 3 can be reached with I
maximum value for R1 is limited by the output resistance of pin 3 which is greater than 10 MΩ typically.
