V IN = 0V
30°C ≤ T A ≤ +70°C
External reference temperature coefficient less than 0.01 ppm/°C.
-2V ≤ V IN ≤ +2V. Error of reading from best fit straight line.
IV IN | = 1.9959
Specification related to clock frequency range over which the TC7135 correctly performs its various functions.
Increased errors result at higher operating frequencies.
