2-Wire Serial 8-Bit DACs with
Rail-to-Rail Outputs
_______________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 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-
erence input for its single DAC and each of the
MAX519鈥檚 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 indi-
vidually or simultaneously. In addition, the devices can
be put into a low-power shutdown mode that reduces
supply current to 4碌A(chǔ). Power-on reset ensures the DAC
outputs 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.
