Notes:
2) For operating athigh 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 theground 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.
