MAX518ACSA+

General Description
The MAX517/MAX518/MAX519 are 8-bit voltage output digital-to-analog converters (DACs) with a simple 2-wire serial interface that allows communication between multiple devices.
They operate from a single 5V supply and their internal precision buffers allow the DAC outputs to swing rail-to-rail.
The MAX517 is a single DAC and the MAX518/MAX519 are dual DACs.
The MAX518 uses the supply voltage as the reference for both DACs.
The MAX517 has a reference input for its single DAC and each of the MAX519’s two DACs has its own reference input.
The MAX517/MAX518/MAX519 feature a serial interface and internal software protocol, allowing communication at data rates up to 400kbps.
The interface, combined with the double-buffered input configuration, allows the DAC registers of the dual devices to be updated individually or simultaneously. In addition, the devices can be put into a low-power shutdown mode that reduces supply current to 4µA. Power-on reset ensures the DAC outputs are at 0V when power is initially applied.
