FAQ

How does the power-down pin function?

The PD pin reduces quiescent current when inactive. The amplifier enables when the voltage exceeds VS minus 1.25 V and powers down when the voltage is lower than 2.5 V from the positive supply.

What is the input common-mode voltage range?

The input common-mode voltage range extends from 0.2 V below the negative supply rail to 1 V below the positive supply rail.
