OPA2330: Current value that the protection diode

Shotaro Sakai

Part Number: OPA2330

Hello team,

Can you give me the information of the current value that the protection diode can tolerate if we have?

Best regards,

Shotaro

    Hi Shotaro,

    the current is automatically limited by the fact that the input voltages are not allowed to exceed the maximum supply voltage, which means 0V for the one input and 7V for the other, in the worst case. Then, the current is limited to 7V / 20k = 350µA. More current isn't possible and isn't allowed.

    By the way, a zero-drift OPAmp can only work properly when the feedback loop is closed and both input voltages assume the same potential. Forcing a differential voltage between the inputs of a zero-drift OPAmp can result in a very weird behaviour.

    Adding to Kai comments, the absolute maximum rated dc input current in most of our IC's is limited to +/-10mA - see below.
