3 Description
The automotive-grade 10-bit DAC53701-Q1 and 8-bit
DAC43701-Q1 (DACx3701-Q1) are a pin-compatible
family of buffered voltage-output smart digital-toanalog
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 DACx3701-
Q1 an excellent choice for applications such as
automotive tail plus brake light, license plate light
fade-in fade-out, and PWM expansion for interior light.
These devices have nonvolatile memory (NVM), an
internal reference, a PMBus-compatible I2C interface,
and a general-purpose input. The DACx3701-Q1
operates with either an internal reference or with the
power supply as a reference, and provides a full-scale
output of 1.8 V to 5.5 V.
The DACx3701-Q1 are smart DAC devices because
of the advanced integrated features. With a forcesense
output, GPI based function trigger, PWM
output, and NVM capabilities, smart DACs enable
system performance and control without the use of
software.
