Part Number: LME49860

Hi Team,

I understand that LME49860 has the clamp diode for INPUT pin (2,3,5,6 pin).

Because, I refer to ABSOLUTE MAXIMUM RATINGS.

And, I guess that LME49860 doesn’t have the clamp diode for OUTPUT A/B (1 & 7pin).

Is my understanding correct?

Hi Kanemaru-san,

Based on this previous post about LME49860 output ESD, there are ESD diodes present at the outputs:

Other Parts Discussed in Thread: LME49860 Hi, Our customers pull up of the output terminal to the high voltage by using a resistor. This high voltage is higher

And also from the data sheet ESD susceptibility table, output pins are listed along with the supply pins:
