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.
