    Theory of Operation Introduction The VMIVME-4116 Digital-to-Analog Converter (DAC) Board performs digital-to- analog conversion on 16-bit positive true offset binary or two’s complement coded words, with an analog output range of -10 to +10 V. This provides for a resolution of 305 µV for each digital input of 1 LSB change.
