Forum Post: LMP91000 WE pin current sense

Dear Domenico,

What's the importance regarding whether current is entering or leaving WE pin of LMP91000 respecto to the Internal Zero ?

My registers are:

Vdd=5V

Vref=2.5V

Bias: 8% VREF

Bias Sign: positive

RTIA = 350Kom

Internal Zero = 20% VREF

For this configuration what is the current range LMP91000 can measure ?

Thank you.

Best regards,

Alejandro
