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 analog supply. VDDA provides the positive supply voltage for

the analog circuitry. The required supply voltage is 3.3V ±10%.

S Negative analog supply. VSSA is the ground reference for the analog

circuitry.

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

pull-down resistors and selectable drive strength.
