Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the

Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect

device reliability.

1. The input common mode voltage or input signal voltage should not be allowed to go negative by more than 0.3 V.

2. The compliance voltage must not exceed the range of − 0.3 to Vref.

3. NCV33035: Tlow = −40°C, Thigh = 125°C. Guaranteed by design. NCV prefix is for automotive and other applications requiring site and change

control.

4. MC33035: TA = −40°C to +85°C; NCV33035: TA = −40°C to +125°C.

5. Maximum package power dissipation limits must be observed.
