CH0- and CH0+ are the fully differential analog voltage
input channels for the current measurement, containing
a PGA for small-signal input, such as shunt current
sensing. The linear and specified region of this channel
is dependant on the PGA gain. This corresponds to a
maximum differential voltage of ±470 mV/G and maximum
absolute voltage, with respect to AGND, of ±1V.
Up to ±6V can be applied to these pins without the risk
of permanent damage
