Notes:
2)
For operating at high temperature, the TDE1798 must be derated based on a 150
°
C maximum junction temperature and the junction-ambient
thermal resistance.
3)
The offset voltage given is the maximum value of input differential voltage required to drive the output voltage within 2V of the ground or the
supply voltage;
4)
Input voltage range is independent of the supply voltage;
5)
The reference input can be the inverting or the non-inverting one.
