THS4531A: Current consumption

Thank you for response. 

The Power-Down pin needs to pulled directly on VDD? Can I add a series resistor to limit the current consumption on this pin?

Regards,

Leonardo

Hello Leonardo,

    You can add a series resistor at the power-down pin, but the voltage at the pin needs to be above 2.1V to enable the amplifier. I am not too sure if current consumption from this pin is modeled here. Let me check with my team on this question, and come back to you by early next week.

Thank you,

In any case the PD pin current is inconsequential to the Icc of the FDA

Hello Sima,

Thank you, I'm waiting it. 

Is true.

In datasheet the bias current of this pin is 50-500nA. But in simulation it consumes ~19mA.
