The MAX517/MAX518/MAX519 are 8-bit voltage outputdigital-to-analog converters (DACs) with a simple 2-wireserial interface that allows communication betweenmultiple devices. They operate from a single 5V supplyand their internal precision buffers allow the DAC outputsto swing rail-to-rail.The MAX517 is a single DAC and the MAX518/MAX519are dual DACs. The MAX518 uses the supply voltageas the reference for both DACs. The MAX517 has a referenceinput for its single DAC and each of theMAX519’s two DACs has its own reference input.The MAX517/MAX518/MAX519 feature a serial interfaceand internal software protocol, allowing communicationat data rates up to 400kbps. The interface, combinedwith the double-buffered input configuration, allows theDAC registers of the dual devices to be updated individuallyor simultaneously. In addition, the devices canbe put into a low-power shutdown mode that reducessupply current to 4μA. Power-on reset ensures the DACoutputs are at 0V when power is initially applied.The MAX517/MAX518 are available in space-saving 8-pin DIP and SO packages. The MAX519 comes in 16-pin DIP and SO packages.
