EVM Operation
0000h corresponding to a -5 V output and FFFFh corresponding to a 5 V
output when BTC/USB = 0. If BTC/USB = 1, 8000h corresponds to -5 V output
and 7FFFh corresponds to 5 V output. Bipolar zero is given by the code 0000h
applied to the DAC.

Similarly, adjusting the V

voltage to any desired value less than 5 V
produces a voltage output range of ±V
