Type Description

AI Positive input for the voltage channel. VP is a differential input with VN. The

typical differential voltage is ±100mV peak.

AI Negative input for the voltage channel. VN is a differential input with VP.

AI Positive input for the first current channel. I1P is a differential input with I1N.

The input gain is programmable depending on the desired current sensor. The

typical differential voltage is ±150mV peak (Gain = 4).

AI Negative input for the first current channel. I1N is a differential input with I1P.

The input gain is programmable depending on the desired current sensor. The

typical differential voltage is ±150mV peak (Gain = 4).

AI Positive input for the second current channel. I2P is a differential input with

I2N. The input gain is programmable depending on the desired current sensor.

The typical differential voltage is ±150mV peak

(Gain = 4).

AI Negative input for the second current channel. I2N is a differential input with

I2P. The input gain is programmable depending on the desired current sensor.

The typical differential voltage is ±150mV peak

(Gain = 4).

S Positive supply voltage for the analog circuitry. The required supply voltage is

3.3V ±10%.

S Ground reference for the analog circuitry.

DIO Programmable multi-purpose input/output, with selectable pull-up or pull-down

resistors and selectable drive strength.
