3 Description
The
10-bit
DAC53401
and
8-bit
DAC43401
(DACx3401) are a pin-compatible family of buffered
voltage-output digital-to-analog converters (DACs).
These devices consume very low power, and are
available in a tiny 8-pin WSON package. The feature
set combined with the tiny package and low power
make
the
DACx3401
an
excellent
choice
for
applications such as LED and general-purpose bias
point generation, power supply control, digitizers,
PWM signal generation, and medical alarm tone
generation.
These devices have nonvolatile memory (NVM), an
internal reference, and a PMBus-compatible I2C
interface. The DACx3401 operates with either an
internal reference or the power supply as a reference,
and provides full-scale output of 1.8 V to 5.5 V. The
devices communicate through the I2C interface.
These devices support I2C standard mode, fast
mode, and fast+ mode.
The DACx3401 are feature rich, and include PMBus
voltage
margin
commands,
user-programmable
power up to high impedance, standalone waveform
generator, medical alarm tone generator, dedicated
feedback pin, and more.
The DACx3401 operate within the temperature range
of –40°C to +125°C.
