Relative Accuracy:
The DAC8311 (14-bit) and DAC8411 (16-bit) are
low-power,
digital-to-analog converters (DAC). They provide
excellent linearity and minimize undesired
code-to-code transient voltages while offering an
easy upgrade path within a pin-compatible family. All
devices use a versatile, 3-wire serial interface that
operates at clock rates of up to 50MHz and is
single-channel,

interfaces.
Low Power Serial Interface with
Schmitt-Triggered Inputs: Up to 50MHz
All devices use an external power supply as a
reference voltage to set the output range. The
devices incorporate a power-on reset (POR) circuit
that ensures the DAC output powers up at 0V and
remains there until a valid write to the device occurs.
The DAC8311 and DAC8411 contain a power-down
feature, accessed over the serial interface, that
reduces current consumption of the device to 0.1µA
at 1.8V in power down mode. The low power
consumption of this part in normal operation makes it
