2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs MAX517/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. ♦
