Note 1: Limit input current to under 100µA if input voltages exceed supply voltage.
2: Full scale voltage = 2V.
3: VIN = 0V.
4: 30°C ≤ TA ≤ +70°C
5: .External reference temperature coefficient less than 0.01ppm/°C.
6: -2V ≤ VIN ≤ +2V. Error of reading from best fit straight line.
7: IVIN| = 1.9959.
8: Specification related to clock frequency range over which the TC7135 correctly performs its various functions. Increased
errors result at higher operating frequencies.
