DAC43401DSGRQ1

The 10-bit DAC53401-Q1 and 8-bit DAC43401-Q1 (DACx3401-Q1) are automotive-class buffered voltage-output smart digital-to-analog converters (DACs) with pin compatibility. These devices feature extremely low power consumption and are available in a tiny 8-pin WSON package. With these features, along with the small package and low power consumption, the DACx3401-Q1 is well-suited for applications such as LED and general-purpose bias point generation, power supply control, and PWM signal generation. These devices are equipped with non-volatile memory (NVM), an internal reference, and a PMBus-compatible I2C interface. The DACx3401-Q1 operates with either an internal reference or a supply reference, providing a full-scale output of 1.8V to 5.5V. The device communicates via the I2C interface. These devices support the I2C Standard Mode, Fast Mode, and Fast + Mode. The DACx3401-Q1 are smart DAC devices due to their advanced integration features. These smart DACs have forced detection outputs, PWM outputs, and NVM capabilities, enabling system performance and control functions without the need for software.
