(MAX517/MAX518)  
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 out-  
puts 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 ref-  
e re nc e inp ut for its s ing le DAC a nd e a c h of the  
MAX519s two DACs has its own reference input.  
Reference Input Range Includes Both Supply Rails  
(MAX517/MAX519)  
Power-On Reset Clears All Latches  
4µA Power-Down Mode  
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 indi-  
vidually 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.
