Note 1:
The TC670 will operate properly over the entire power supply range of 3.0V to 5.5V. As VDD varies from 3.0V, accuracy will degrade
based on the percentage of VDD as shown in Section 3.0.
Electrical Characteristics: Unless otherwise specified, all limits are specified for -40°C to +85°C and VDD =3.0V to5.5V
