1.
The maximum reference voltage accepted by the device depends from the supply voltage Vs (see Figure 7).
2.
To reduce the switching losses the base bias of the bridge's low side NPN transistor is proportional to the DAC output, then
the output current driving capability is also proportional to the DAC output voltage (see Figure 6 and Figure 8 for
DAC=100%, it is proportional for lower percentages).
