19-0393; Rev 1; 9/02 2-Wire Serial 8-Bit DACs withRail-to-Rail OutputsMAX517/MAX518/MAX519_______________General Description____________________________Features The MAX517/MAX518/MAX519 are 8-bit voltage output ♦ Single +5V Supply digital-to-analog converters (DACs) with a simple 2-wire ♦ Simple 2-Wire Serial Interface serial interface that allows communication between ♦ I2C Compatible multiple devices. They operate from a single 5V supply ♦ Output Buffer Amplifiers Swing Rail-to-Rail and their internal precision buffers allow the DAC out- puts to swing rail-to-rail. ♦ Space-Saving 8-pin DIP/SO Packages(MAX517/MAX518) The MAX517 is a single DAC and the MAX518/MAX519 ♦ Reference Input Range Includes Both Supply Rails are dual DACs. The MAX518 uses the supply voltage (MAX517/MAX519) as the reference for both DACs. The MAX517 has a ref- erence input for its single DAC and each of the ♦ Power-On Reset Clears All Latches MAX519’s two DACs has its own reference input. ♦ 4µA Power-Down Mode The MAX517/MAX518/MAX519 feature a serial interface ______________Ordering Information and internal software protocol, allowing communication at data rates up to 400kbps.
