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-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 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 their advanced integrated features. With force-sense output, GPI based function trigger, PWM output, and NVM capabilities, smart DACs enable system performance and control without the use of software.
