Description
The 10-bit DAC53701 and 8-bit DAC43701 (DACx3701) 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 an excellent choice for applications such as appliance door fade-in fade-out, processorless LED dimming with PWM input, general-purpose bias point generation, voltage margining and scaling, PWM signal generation, and medical alarm tone generation.
These devices have nonvolatile memory (NVM), an internal reference, a PMBus-compatible I2C interface, and a general-purpose input. The DACx3701 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 are smart DAC devices because of their advanced integrated features. With force-sense output, GPI based function trigger, medical alarm, PWM output, and NVM capabilities, smart DACs enable system performance and control without the use of software.
