The MAS9181 comprises eight digital to analog
converters (DACs) each controlled by a two-wire I2C
bus. The DACs are individually programmed using an 8-
bit word to select an output from one of 256 voltage
iCPEEisteps. The maximum output voltage of all DACs is set
by Vmax and the resolution is Vmax/256. At power-on all
outputs are set to their lowest value. The I2C-bus slave
receiver has 3 programmable address pins (2 for
MAS9181 CS).
