open-in-new Find other Precision DACs (<=10MSPS)

Description

The 10-bit DAC53401-Q1 and 8-bit DAC43401-Q1 (DACx3401-Q1) are a pin-compatible family of automotive, 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 DACx3401-Q1 an excellent choice for applications such as LED and general-purpose bias point generation, power supply control, and PWM signal generation.

These devices have nonvolatile memory (NVM), an internal reference, and a PMBus-compatible I2C interface. The DACx3401-Q1 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 plus.

The DACx3401-Q1 are smart DAC devices because of their advanced integrated features. The force-sense output, PWM output, and NVM capabilities of these smart DACs enable system performance and control without the use of software.
