Note 1: Limit input current to under 100 µA 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 0.01 ppm/°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.
