These devices consume very low power, and are available in a tiny 8-pin WSON package. The feature set bined with the tiny package and low power make the DACx3401 an excellent choice for applications such as LED and general-purpose bias point generation, power supply control, digitizers, PWM signal generation, and medical alarm tone generation. These devices have nonvolatile memory (NVM), an internal reference, and a PMBus-patible I2C interface. The DACx3401 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 municate through the I2C interface. These devices support I2C standard mode, fast mode, and fast+ mode. The DACx3401 are feature rich, and include PMBus voltage margin mands, user-programmable power up to high impedance, standalone waveform generator, medical alarm tone generator, dedicated feedback pin, and more. The DACx3401 operate within the temperature range of - 40°C to +125°C. Device Information(1) PART...
