TEST

Bridge Drive Current Mode Setting

High ESD and Scan Path Output Signal. May need a 0.1µF capacitor, in

noisy environments. OUT may be parallel connected to DIO.

Negative Supply Voltage

Bridge Negative Input. Can be swapped to INP by configuration register.

Bridge Drive

Bridge Positive Input. Can be swapped to INM by configuration register.

Positive Supply Voltage. Connect a 0.1µF capacitor from VDD to VSS.

No Connection. Not internally connected; leave unconnected (TQFN

package only).

Internally Connected. Connect to VSS.
