DESCRIPTION
The MAS8444a comprises eight digital to analog converters (DACs) each controlled by a two-wire I2C bus. The DACs are individually programmed using an 6-bit word to select an output from one of 64 voltage steps. The maximum output voltage of all DACs is set by Vmax. At power-on all outputs are set to their lowest value. The I2C-bus slave receiver has 3 programmable address pins (2 in the SO16 package).
