Hello,

Someone can tell me if this AOP, TLV274 , has internal protection diodes on its inputs V+ and V- ?

Zodiac,

TLV274 has diode from each input and output pin to both power pins. V+ and V-

Hello ronald,

Thank you for your answer.
Can you tell me at which voltage they clamp?

Regards,

Voltage depends on current and temperature. I recommend that current says under +/-1mA. Keep in mind that all current to V+ diode and V- diode must be used by the system. In other words V+ diode current tries to power up V+ bus.

Room temperature curve; input current and input voltage. V+ = V- = 0V
